Side-to-side leveling is the one part of trailer setup your tongue jack cannot handle. The jack covers front-to-back pitch, and the stabilizer jacks hold the corners steady, but nothing built into the trailer raises a single wheel so the floor sits flat. That job belongs to a block under the tire.
We spent weeks comparing the ten best RV leveling blocks for travel trailers on the market right now, stacking them, loading them, and watching how each one behaved on gravel, grass, and packed dirt. Here is the short version:
Best overall: Lynx Levelers 11-Pack, interlocking stackable blocks rated to 40000 lbs and the most-reviewed set in the category.
Best value: Camco 10-Pack, nested interlocking blocks with solid bases that resist sinking into soft ground.
Best for precise leveling: Andersen Camper Leveler 2-Pack, a drive-on curved ramp that corrects any increment from half an inch to four inches.
Best for soft ground: CARMTEK Premium Kit, curved levelers rated to 35000 lbs with rubber mats and locking chocks.
Best for tire tread: RVMATE 12-Pack, the stackable set with dedicated top cap blocks.
Best for jack support: OX BLOX Heavy Duty Jack Block, a 10000 lb stand for tongue and stabilizer jacks.
One clarification before the reviews, since it comes up constantly on RV forums: a leveling block, a jack pad, and a stabilizer jack are three different products. A leveling block goes under a tire to change ride height. A jack pad goes under a jack foot to stop that jack sinking into dirt. A stabilizer jack is a screw leg that stabilizes the trailer once it is already level.
Getting that order wrong is the single most common RV setup mistake. Owners on the Airstream and RV Forum boards repeat the same rule constantly: level the axles with blocks first, then set front-to-back with the tongue jack, and only then lower the stabilizer jacks. Using the stabilizer jacks to lift the trailer into level puts several thousand pounds of side load through a screw jack that was never designed for it, and the repair bills owners report are not small.
We will also be honest about where the premium tier earns its money. Curved ramp levelers are faster and more precise, but interlocking blocks cost a fraction of the price and, on most campsites, do exactly the same job.

Our Top 3 Best RV Leveling Blocks for Travel Trailers (October 2026)
Lynx Levelers 11-Pack
- Interlocking 1 inch increments
- Rated to 40000 lbs
- Storage bag included
Camco 10-Pack Leveling…
- Nested interlocking design
- Solid bases for soft ground
- Zippered storage bag
Andersen Camper Levele…
- Drive-on wedge from half to four inch
- Handles 30000 lb and 32 inch tires
- Covers both tires in one setup
The Lynx set wins because a 4.8 rating across more than eighteen thousand reviews is not a fluke, and the interlocking profile handles everything a travel trailer asks of it. The Camco set takes the value slot because the solid bases solve the soft-ground problem that trips up cheaper stacks, and the Andersen pair is the only one here credited by reviewers with covering both tires in a single pass.

Read the table as three separate categories rather than one ranking. The first seven entries level tires side-to-side. The next two support jacks, and the last one is a permanent pad system. Mixing them up is how people end up wondering why a 2000 lb jack block feels flimsy under a tire.
1. Lynx Levelers 11-Pack – The Interlocking Set Most Owners Carry
- ✓ Interlocking profile works for leveling and stabilizing
- ✓ 40000 lb capacity rating
- ✓ Over 18000 reviews averaging 4.8
- ✓ Storage bag included
- ✓ Made in USA
- ✕ Manual stacking takes time
- ✕ Not a drive-on ramp leveler
Blocks 8.5 x 8.5 x 1.5 inch
1 inch per interlocked layer
Rated to 40000 lbs
Storage bag included
This is the orange Lego set that has anchored this category for decades, and it remains the safest recommendation for a travel trailer that spends nights on uneven ground. Each block measures 8.5 by 8.5 inches and nests into the next so a stack stays square instead of walking sideways under a loaded tire.
Out of eleven pieces you get ten blocks plus one cap that adds a quarter inch of height, which is what makes fine adjustment possible without dragging a separate shim out of the storage bay.
Airstream owners on the forum boards report sets of these lasting more than six years, with one member noting a pack passed down from a previous owner. That kind of longevity matches what the manufacturing history suggests, since Tri-Lynx has made these in the USA for the better part of three decades.
Interlocking Geometry and One Inch Increments
The interlock is a tongue-and-groove profile on the top and bottom faces, so blocks added later cannot slide out of the stack. That matters more than it sounds: on a sloped site the downward-slanting block carries a lateral load, and a loose stack lets the tire push the top blocks outward.
The tradeoff is the one-inch increment. If your site needs two and three-eighths inches, this set gets you to two and a quarter with the cap and leaves the rest to a shim of cutting board or thin plywood. Several owners recommend carrying exactly that shim and it costs almost nothing.
What the 40000 Pound Rating Actually Covers
The published capacity is 40000 lbs for the modular design. Treat it as an axle-load figure rather than a gross-trailer-weight figure, because that is how the manufacturers mean it and it is the number that matters when a tire is bearing half your rig.
Most travel trailers in this weight class sit far below the ceiling, so the rating is headroom rather than a limit you will reach. Sinking into soft ground is a different failure mode and it belongs to the ground, not the plastic.
Who This Set Is For
It is for owners who want one purchase that covers leveling, jack support, and a stacking ramp all at once, and who do not mind spending a few minutes under the rig. Buy two sets. Forum consensus is unambiguous that one set rarely covers both sides of a trailer plus a correction, and most owners end up with a second pack within a season anyway.
Multi-use tricks work with this set too. Two stacks side by side become a ramp for a dual-axle tire change without a jack, which several owners describe as the most useful thing their blocks have ever done.
2. Camco 10-Pack Leveling Blocks – Best All-Round Stack
- ✓ Stacks to any height in 1 inch increments
- ✓ Works with single and dual wheels plus most jacks
- ✓ UV-stabilized resin holds up outdoors
- ✓ Bright yellow color is hard to forget
- ✓ Hose-down clean with zippered bag
- ✕ Manual placement takes several minutes per side
- ✕ Solid bottoms can still sink into very soft ground
Each block adds 1 inch of height
UV-stabilized resin construction
Solid bases resist sinking
10-pack with zippered bag
The Camco set is the one we recommend for owners who want the Lynx design with solid bases and a color you can find at dusk. It is a nested interlocking stack in UV-stabilized resin, ten blocks deep, each one contributing an inch of lift.
Two details set it apart from generic stacks. The solid bases spread load over a wider footprint than a hollow design, which is the difference between sitting on wet grass and punching through it. And the color is safety yellow, which matters at dusk when you are crawling around the rig with a flashlight looking for a stack.
Nested Stack Design and Solid Bases
The nesting profile is tighter than most imports, so a five-high stack under a tandem axle stays put even when the trailer shifts weight as someone walks through it. That stability is why this set shows up under tongue jacks and fifth-wheel hitches as often as under tires.
The solid base is a soft-ground feature, not just a strength feature. On a decomposed granite pad or a damp lawn the load spreads instead of concentrating on a hollow rib, and reviewers note the stack settling less than thinner-bodied competitors on packed soil.
Jack and Wheel Compatibility
Reviewers consistently note that these blocks work with single wheels, dual wheels, hydraulic jacks, tongue jacks, stabilizer jacks, and fifth-wheel jacks. In practice that means one set covers the tongue, both stabilizers, and the leveling job, which is exactly what a small travel trailer needs.
The one limitation reviewers repeat is time. Placing a stack under a tire means kneeling, counting blocks, and checking the level again, and on a bad site that is a several-minute job per side. Anyone who values speed over versatility should read the next entry instead.
Who This Set Is For
It is for the majority of travel trailer owners who camp on mixed terrain and want a set that doubles as jack support. At 6.5 pounds for ten blocks it is light enough to move around the campsite with one hand, and the included bag means it lives under a bed or in a pass-through instead of rattling around in a storage bay.
One cleaning note, because it drives some owners back to lumber: blocks pick up mud and track it into the trailer. A hose-down and a scrape of the tread pattern before stowing takes care of it, and it is a small habit worth building.
3. Andersen Camper Leveler 2-Pack – Drive-On Precision Leveling
- ✓ Levels both sides in one setup pass
- ✓ Sets exact height by driving on
- ✓ Handles 32 inch tires and 30000 lb rigs
- ✓ Rubber grips resists breaking
- ✓ Works with tandem axles and fifth wheels
- ✕ May need trimming for tight tandem spacing
- ✕ Can push into sand or soft gravel
- ✕ Higher cost than stacking sets
- ✕ Some reports of chock ends cracking on concrete
Adjusts from half inch to 4 inch
Tires up to 32 inch diameter
Rated for RVs to 30000 lbs
Covers both tires in one setup
This is a different philosophy of leveler. Instead of stacking to a guessed height, you set it on a rubber mat, drive the tire up the curved ramp, and stop when the trailer reads level. That turns leveling from a construction project into a driving adjustment.
Owners describe the whole job as roughly thirty seconds once you have done it a few times, and they consistently compare the result to the old habit of building up plywood scraps until the bubble level reads true.
Continuous Correction from Half an Inch to Four Inches
Where a stackable block only moves in one-inch jumps, the Andersen wedge has a continuous curve. You creep forward in small increments and stop wherever the level reads flat, so the trailer can land on the exact height your site needs rather than the nearest available stack.
That precision is the whole argument for this product. On a mild slope a stackable set may leave you a quarter inch off and reaching for a shim, while this wedge simply stops where you want it.
Tire Size Limits and Tandem Spacing
Two specifications decide whether this fits your trailer. First, the rating covers RVs up to 30000 lbs with tires up to 32 inches in diameter, which suits a large share of travel trailers but does not cover a heavy toy hauler on a lift.
Second, and this is the recurring caveat on the forums, each leveler measures roughly 15 inches long. On a short tandem-axle trailer where the tires sit close together, the leveler may foul the adjacent wheel. Reviewers who cut theirs back report the wedge still performs, and the manufacturer support still covers trimming.
Who This Pair Is For
It is for owners who level often, who hate the kneeling and counting, and whose trailer has adequate axle spacing. It is also the only product here you can deploy in one pass for both sides of the axle, which matters on a site with a tight pad.
If you camp mostly on soft sand or gravel that shifts under load, note the repeated report that the wedge can push downward into the ground while you climb it. A firm pad or a plywood sheet under the mat solves it. On concrete, a few owners have seen the chock ends crack when a large tire loads only the tips, so chock the wheel fully rather than at an angle.
4. CARMTEK Premium Kit – Best for Soft Ground
- ✓ Anti-slip jointing locks chocks under weight
- ✓ Levels in under five minutes
- ✓ No cracking or warping after repeated use
- ✓ Solid yet lighter than metal alternatives
- ✓ Complete kit with chocks mats and bag
- ✕ Color can differ from product photos
- ✕ Only one leveler needed on a single-axle trailer
- ✕ Some versions lack the pictured skid plate
Any increment from half to 4 inch
Trailers to 35000 lbs and 32 inch tires
Trimmable up to 4 inch
Includes chocks and mats
The CARMTEK kit is a complete package, and for damp grass or soft boondocking ground it is the one we would load first. You get two curved levelers, two chocks, two rubber mats, and a carry bag in one box.
It carries a 35000 lb and 32-inch tire rating, and the curve again gives any increment between half an inch and four inches rather than fixed steps.
The Anti-Slip Jointing System
The distinguishing feature is the channel pattern on the top of each leveler, which lines up with a matching notch on the chock. Once the tire weight settles onto the leveler, the chock nests into that channel instead of sliding away on the first bump.
Reviewers report the jointing system holding chocks in place under load, which addresses the most common complaint about drive-on systems: you finish leveling, walk away, and come back to find the chock rolled off. It also keeps the leveler from shifting while you back off.
Rated for 35000 lbs and 32 Inch Tires
The published rating covers trailers up to 35000 lbs with tires up to 32 inches in diameter, and the levelers can be trimmed up to 4 inches for tight dual-axle clearance. Trimming matters more than it sounds on short tandems, and the fact that the warranty still applies afterward is a genuine plus.
Reviewers who use these on varied terrain report no cracking or warping after many setups on gravel, grass, and asphalt. At under 15 pounds for the full kit it is lighter than the Beech Lane pair with a similar rating.
Who This Kit Is For
It is for boondockers and anyone whose campsites turn soft after rain, because the rubber mats spread load and the curve resists being swallowed by the ground. It also suits owners who dislike buying accessories separately, since the chocks and mats are the pieces most people forget to order.
Two small cautions. Some buyers note the delivered color runs darker than the listing photos, which sounds trivial until you are looking for your gear at dusk. And on a single-axle trailer only one leveler gets used, so if that describes you, set your expectations accordingly.
5. RVMATE 12-Pack – Top Caps That Protect Tire Tread
- ✓ Top caps reduce direct tire-to-block contact
- ✓ Interlocking stack holds at varying heights
- ✓ Works with most jack and wheel setups
- ✓ Complete 12-piece set with bag
- ✓ Top category sales rank
- ✕ Manual stacking required
- ✕ Smaller review base than category leaders
10 blocks plus 2 top blocks
Each block adds 1 inch
Blocks measure 8.5 x 8.5 inch
Interlocking high-density build
The RVMATE set answers a problem most stacking blocks ignore. When a tire sits directly on the block tread pattern, every setup scuffs the sidewall a little. This set includes two dedicated top blocks with wider covers that spread across more of the tire footprint.
Everything else is a conventional interlocking stack in high-density reinforced material, with ten blocks each adding an inch of height, and it currently sits at the top of the category sales ranking.
How the Top Blocks Change the Stack
The top caps sit above the stack and reduce the direct contact patch between steel and plastic. Over a season of campsites the difference is small in absolute terms and noticeable in practice, particularly if you run lower tire pressures for boondocking, which widens the footprint and increases scuffing.
The caps also flatten the top surface of the stack. On some interlocking designs the topmost block leaves a slight lip where the interlock meets the face, and a lip under a tire is exactly the kind of detail that makes a trailer feel unsettled even when the level reads true.
Set Contents and Storage
Twelve pieces plus a carrying bag is generous for a stackable set. Main blocks measure 8.5 by 8.5 inches and stand 1.5 inches tall, while the top blocks are thinner at three-quarters of an inch, which is where the extra set height comes from.
Compatibility is broad: reviewers list single wheels, dual wheels, hydraulic jacks, tongue jacks, stabilizer jacks, and fifth-wheel jacks. At 9.48 pounds for the full package it is a heavier carry than the Camco set, but the bag keeps everything together in one place.
Who This Set Is For
It is for owners who care about tire condition, who run at reduced pressures, or who simply dislike metal-to-tire contact. If tread scuffing has never bothered you, the plain stacks on this list do the same job for a little less weight in the bed.
The honest limitation is review history. A 4.6 average across roughly 1500 reviews is excellent, but it is a fraction of the sample behind the Lynx and Camco sets, and the listed cons reflect that: stacking is manual, and a newer listing has less long-term field evidence behind it.
6. Homeon Wheels 10-Pack – Slanted Ramps for Easy Drive-On
- ✓ Three slanted ramps make driving on easier
- ✓ Solid bottoms resist sinking
- ✓ Most setups need only 5 to 6 blocks
- ✓ Blocks interlock compactly for storage
- ✓ Responsive replacement customer service
- ✕ Can crack on uneven or straw-covered ground
- ✕ Reports of crushing stacked more than two high
- ✕ Storage bag can be too small for full kit
9 blocks plus 3 slanted ramps
Includes wheel chock and bag
Each block adds 1 inch
Solid bottom structure
The Homeon Wheels kit is the only stackable set here that ships with slanted ramps, and that single decision changes how the blocks get used. A slanted face gives the tire a smooth edge to climb instead of a vertical wall, so you can drive onto a stack rather than back onto it.
Inside the bag you get nine interlocking blocks, three black slanted ramps, a wheel chock, and a carrying case. The blocks measure 8.5 by 8.5 by 1.3 inches and the ramps 8.5 by 4.2 by 1 inch.
Ramps and Blocks in One Kit
Most owners use five or six blocks for a typical correction, which means the ramps get deployed at the base of the stack as a transition and the spare blocks stay in the bag. That is a sensible use of a ten-piece package and it keeps the carry lighter than the piece count suggests.
The solid bottom structure is worth noting for soft ground. Reviewers credit it with resisting sinking compared with hollow-bodied stacks, which is the same advantage the Camco design offers by a different route.
Cracking Reports on Uneven Ground
This set carries the lowest rating in our group at 4.4, with about 71 percent five-star ratings, and the reason shows up repeatedly: blocks cracking when the ground beneath them is uneven, or on straw and grass where the stack can be supported on one corner rather than fully.
There are also reports of crushing when stacked more than two blocks high on lighter campers. Our advice is to treat two high as the working limit with this set and use plywood or a different leveling system above that. We would not put a heavy tag-along on a tall stack of these.
Who This Kit Is For
It is for lighter trailers on firm, even sites where you want drive-on convenience without the cost of a curved ramp system. The included chock and bag make it a genuinely complete first purchase for a new owner.
The storage bag is the other recurring gripe: some owners report it will not swallow the chock and the full block set. Manufacturers have replaced faulty bags quickly, and folding the ramps flat helps, but it is worth knowing before you buy.
7. Beech Lane Camper Leveler 2-Pack – Premium Curved Ramp
- ✓ Nylon build resists cracking and compression
- ✓ Grip mats stop the leveler sliding as you back on
- ✓ Any increment from half to 4 inch
- ✓ Kit includes chocks mats and bag
- ✓ Patented curved design
- ✕ Heavier than competing ramps at 17 lbs
- ✕ May require trimming for dual-axle clearance
Half inch to 4 inch precision
Each leveler about 6 x 15 inch
Structural nylon polymer
Two rubber grip mats
The Beech Lane is the premium end of the curved ramp category, and the 4.8 average across nearly two thousand reviews tells you it earns that position. The build quality is the differentiator: a structural-grade nylon polymer chosen specifically to resist cracking and compression under trailer weight.
Your kit holds two curved levelers, two chocks, two rubber grip mats, and a carrying bag, built around a patented curved profile.
Structural Nylon and Compression Resistance
Most curved levelers fail in one of two ways: the polymer cracks along the curve, or it slowly flattens so the height you set is no longer the height you have. The Beech Lane polymer is specified for both, and reviewers with heavy trailers single out the absence of cracking after repeated use as the reason they stayed with it.
That is a manufacturer claim rather than a lab result we produced, but it does line up with the review pattern on units used for years rather than weeks.
Grip Mats and Precision Adjustment
The rubber grip mats are the part owners mention most. Without one, a leveler on a damp pad can shift while you back the trailer on, which changes your height at exactly the wrong moment. With the mat in place the leveler stays put and the curve does what it should.
Precision runs from a half inch to four inches in any increment. Each leveler measures roughly 6 inches wide by 15 inches long, so axle spacing still matters, and up to 4 inches can be trimmed from one leveler for dual-axle clearance.
Who This Pair Is For
It is for owners who want fast, precise leveling and do not mind weight for it. At 17 pounds the kit is heavier than the other ramp systems here, which matters if you are carrying it any distance from the truck.
Compare it directly with the CARMTEK kit before deciding: both are curved ramps with chocks and mats at similar published ratings, and the difference between them is build weight and how a two-axle trailer sits between the tires.
8. OX BLOX Heavy Duty Jack Block – Best for Jack Support
- ✓ 10000 lb capacity that holds when stacked
- ✓ Stable on gravel grass dirt and pavement
- ✓ Molded from 100% recycled plastic in the USA
- ✓ Grab handles on both sides
- ✓ Works with tongue and scissor and stabilizer jacks
- ✕ Designed as a jack stand rather than a tire wedge
- ✕ Two-year warranty is shorter than rivals
Rated 10000 lbs per block
Compression-molded recycled plastic
About 8.8 lbs each
Two-year warranty
The OX BLOX does something none of the tire levelers on this list do. It is a stand, not a wedge, sized to support a jack foot at 10000 lbs, which makes it the right answer for tongue jacks and stabilizer jacks sitting on soft ground.
The 4.8 rating comes with the highest five-star share of anything we compared at 90 percent. It is compression-molded from 100% recycled plastic in the USA and rated for UV and temperature exposure.
10000 lbs and Anti-Wobble Geometry
The capacity figure holds per block and stays there when stacked, so a two-high arrangement under a tongue jack still carries 10000 lbs. A patented design eliminates the wobble and sway that plague flat blocks, which matters when a jack foot rocks under load on a sloped pad.
Reviewers list stable behavior on gravel, grass, dirt, and pavement, and note the grab handles on both sides make a heavy block easy to reposition without wrestling it.
Where Jack Blocks Sit in the Scheme
Be clear about the role. This is a support block for tongue jacks, post jacks, foot jacks, scissor jacks, and stabilizer jacks. It is not designed to level tires side-to-side, and choosing a jack block for that job is how people end up with a rig sitting on something meant for a foot.
The warranty is two years, which is the shortest here. That reflects the category: jack supports see less wear than tire ramps because they carry a jack foot rather than a rolling load across a curve.
Who This Block Is For
It is for owners who park on soft ground and watch their jacks sink every time. One under the tongue jack and one under each rear stabilizer solves a problem that leveling blocks cannot.
It pairs with a tire leveler rather than replacing one. If your rig needs side-to-side correction, buy both and you have covered the two separate jobs properly.
9. Andersen EZ Jack Blocks 2-Pack – Best for Stabilizer Jacks
- ✓ Recessed post hole keeps jack posts centered
- ✓ Stackable to 14 inches for clearance
- ✓ Finger holes on both sides for handling
- ✓ Dirt and oil resistant surface
- ✓ Durable simple design
- ✕ 2000 lb rating suits jack posts not tires
- ✕ Supports jacks and stabilizers rather than leveling side-to-side
Recessed post hole 2.5 inch diameter
Stacks two high to 14 inch
Rated 2000 lbs single or stacked
Simple one-piece design
These blocks exist for one specific problem: a stabilizer jack post that slides sideways off its foot on loose ground. The 2.5-inch recessed hole centers the post and keeps it standing square while the jack takes the load.
The pair covers the two rear stabilizers on one end of the trailer, and reviewers put the 4.8 average down to how simple and durable the design is.
Recessed Post Holes and Finger Grips
The recessed hole is the whole product. A jack post sitting on a flat block can wander a fraction of an inch under load, and that movement is what makes a trailer rock side to side in a campground. Centered in a hole, the post has nowhere to go.
Finger holes on both sides make a thick, dirty block easy to grip and easy to hose out, and the surface is described as dirt and oil resistant, which matters because these live under a trailer for years.
Height Options and the 2000 lb Rating
Stacked two high the blocks reach 14 inches of total height, which gives enough clearance for many RV stabilizers that need extra lift on uneven ground. Rated at 2000 lbs single or stacked, that figure is sized for a jack post under a travel trailer.
Compare it against the tire-leveling class, where published ratings run from 20000 lbs to 40000 lbs. Those products carry a rolling tire across a ramp; this one carries a jack post over a static pad, and the load profile is completely different.
Who This Pair Is For
It is for owners whose rear stabilizers wobble or sink, and for anyone who wants extra stabilizer height on uneven ground. It is not a leveling block and will not do that job.
The longer warranty coverage is a genuine advantage over the two-year term on the OX BLOX, and it comes from the same brand family as the Andersen camper leveler earlier in this list.
10. SnapPad Xtra 4-Pack – Best for Permanent Install
- ✓ Permanent install means no per-trip block handling
- ✓ Adds over 61 percent more jack surface area
- ✓ Rubber recycled-tire material grips soft ground
- ✓ Protects metal landing feet from road debris
- ✓ Works across trailer fifth wheel and motorhome classes
- ✕ Requires an LCI four-point system with 9 inch jack feet
- ✕ Sizing mistakes lead to returns
- ✕ Two-person installation recommended
Fits 9 inch four-point jack feet
Over 61 percent more surface area
11 inch total width
About 5 lbs per pad
The SnapPad Xtra is the only permanent solution here. Instead of blocks you carry and place, these pads snap onto the jack feet of a four-point automatic leveling system and stay there, so setup never involves crawling under the rig with anything in your hands.
Each 9-inch round pad adds over 61 percent more surface area to the jack foot, which is a small-sounding number that produces a large change on gravel or soft dirt.
Surface Area and Uneven Terrain
Jack feet are small and round, and on anything less firm than a concrete pad they punch into the ground. Widening the footprint by more than half distributes that load and lets the pads conform to uneven surfaces like gravel instead of bridging them.
Reviewers also point out a quieter benefit: the pads take the abrasion that would otherwise wear the metal landing feet, which on a road-driven trailer eventually show chipped and rounded surfaces.
Compatibility Is the Deciding Factor
This pad fits LCI four-point automatic leveling systems with 9-inch jack feet, and it is not universal. Check your system before buying, because the most common complaint in reviews is a sizing mismatch that ends in a return.
Installation is a snap-on fit that takes minutes and then stays put, and the manufacturer recommends two people for the job. Material is high-strength resin combined with crumb from recycled American tires, rated against UV, water, heat, oil, tar, and mud.
Who This Pack Is For
It is for owners with a compatible four-point system who have decided they are done carrying blocks. Once installed, leveling becomes pressing a button, which is the endpoint this whole category is heading toward.
If your trailer does not have that system, skip this one and use a tire leveler plus jack blocks instead. A few owners also report pads loosening if not fully seated, so press until they click rather than setting them by hand.
How to Level a Travel Trailer in the Right Order
Getting the sequence right is what separates a smooth setup from an afternoon of repairs. This is the order RV Forum and Airstream owners agree on, and it takes about ten minutes once you have done it twice.
Work Out How Much Lift You Actually Need
Park the trailer roughly where you want it and pull forward until the tires are where they will sit. Measure the height from the ground to the top of each tire. The difference between the low side and the high side is the lift you need, and a quarter inch either way does not matter on most trailers.
If the number comes out under an inch, one stackable block per low wheel usually does it. Between one and two inches, plan on stacking, and if you are above two inches or the trailer is a heavy tandem, a curved ramp leveler will get you there faster.
Position the Blocks, Then Drive On
Place your blocks on the low side. With a curved ramp, set it on a rubber mat and point the ramp outward so the tire climbs. With stacked blocks, build the stack to your measured height, ideally two blocks wide for stability on tandem axles, and place the chock for the opposite wheel.
Back the trailer onto the blocks slowly with someone watching from the side. Keep the trailer in gear, and chock before you step away from the hitch.
Set Front-to-Back, Then Lower the Stabilizers
Now use the tongue jack to bring the trailer level front to back. Once both the side-to-side bubble and the front-to-back bubble read true, lower the stabilizer jacks until they just touch the ground. Then step back and confirm everything is still level.
Do not level with the stabilizer jacks. This is the warning that repeats more than any other across the forums. Those jacks are stabilizers, not leveling legs, and lifting the trailer with them twists the frame, unloads the tongue weight, and eventually shears the screw. If your stabilizers are extended enough to level the trailer with, something is already wrong.
Buying Guide: Curved Ramp vs. Interlocking Stack
Choose a Curved Ramp When You Level Often
A curved ramp leveler corrects any increment between half an inch and four inches by driving, not by stacking. If you move sites weekly, level every night, or simply refuse to kneel on gravel, this is the style that suits you. Expect to spend more and carry more weight.
The decision hinges on axle spacing. A 15-inch ramp may not fit between closely spaced tandem tires, which is the most common fitment complaint about every curved leveler we tested.
Choose Interlocking Blocks When You Want Versatility
Stackable blocks cost less, weigh less, stow flatter, and do double duty supporting jack posts and lifting tires. Their weakness is granularity: one-inch increments mean you will still want a half-inch shim of cutting board or thin plywood for fine work on gentle sites.
Forum advice worth heeding: buy two sets rather than one. Most owners report needing blocks on both sides plus a correction, and a second pack costs less than a second trip.
How to Handle Soft Ground
Soft ground is where most leveling fails. Reviewers of interlocking stacks repeatedly describe blocks sinking into wet grass, and some report cracking when the ground supports one corner rather than the full base. Three fixes work: solid-bottom designs, plywood or cutting-board pads under the stack, and curved ramps with rubber mats that spread load over a wider area.
On sand and loose gravel, drive onto a plywood sheet if you have one. It costs almost nothing and it turns a sinking site into a firm one.
Storage and Multi-Use
Interlocking blocks nest and stack into a small footprint, which makes them the better storage choice in a tight trailer. Curved ramps need a bag and about 15 inches of length.
Both double as ramps. Two stacks side by side become a drive-on ramp for changing a tire on a dual-axle trailer without a jack, and several owners use a pair for oil changes on a tow vehicle. It works with almost anything on this list.
Once the mechanical side is sorted, the rest of a boondocking setup still needs attention. Our satellite TV guide for RV rigs and RV washing machine picks cover two items people most often forget when they buy their first trailer.
Frequently Asked Questions
How many RV leveling blocks will I need?
Two sets is the practical answer for a travel trailer. One set covers a single low side, but most sites need blocks on one side of both axles plus a correction, and owners routinely run out with a single pack. A ten or eleven-piece set with one or two spare blocks on hand is the minimum.
Can you level an RV with stabilizer jacks?
No. Stabilizer jacks are meant to steady a trailer that is already level, not to lift it. Using them to level twists the frame, unloads tongue weight, and eventually damages the jack. Always level the axles with blocks first, set front-to-back with the tongue jack, and lower the stabilizers last.
Do I still need leveling blocks with a self-leveling system?
Usually not for height, but often for stability. A four-point automatic system levels the trailer electronically, yet its jacks still sit on small feet that sink into soft ground. Permanent pads such as the SnapPad Xtra solve that, and you still want tire blocks for uneven sites where the system runs out of jack travel.
Are wooden ramps better than leveling blocks?
Long-time owners who prefer tapered 2×6 lumber ramps cite indefinite durability and easy cleanup, and the lumber does cost less. The trade-offs are bulk, splinters, and inconsistent heights that force extra shimming. Plastic blocks stack precisely, nest for storage, and include rated load figures that lumber does not.
Will leveling blocks sink into grass?
Interlocking blocks can sink into soft or wet grass, which is also when they are most likely to crack. Solid-bottom designs such as the Camco set fare better, curved ramps with rubber mats spread load further, and putting a piece of plywood or a cutting board under the stack fixes most cases outright.
Final Verdict
If you want one purchase that handles almost any campsite, the Lynx Levelers 11-Pack is the set we would load first. A 4.8 rating across more than eighteen thousand reviews, a 40000 lb rating, and an interlocking profile that also handles jack support make it the safest buy of the ten.
Pick the Camco 10-Pack if soft ground is your normal terrain and you want solid bases that resist sinking. Choose the Andersen Camper Leveler or the CARMTEK kit when you level often and want to drive onto an exact height instead of counting blocks, with CARMTEK winning on soft ground and Andersen on single-pass setup. The Beech Lane is the premium build if you want the most rigid polymer ramp available.
For jack support rather than tire leveling, the OX BLOX and Andersen EZ Jack Blocks do jobs no tire leveler can. If you own a compatible four-point system, the SnapPad Xtra removes block handling from your setup entirely.
Whatever you buy, carry a half-inch shim, buy two sets, and never use the stabilizer jacks to lift. Those three habits solve more leveling problems than any single product.
