RV Leveling Blocks That Stop the Rocking
The Andersen Camper Leveler 3604 is our overall pick because it levels in one pull-forward with no stacking. The Camco FasTen 44510 blocks remain the most versatile locking system, while the Lynx Levelers 00015 offer the highest stack for badly sloped sites.
For fast side to side leveling on a travel trailer, the Andersen Camper Leveler 3604 gets you level in one motion, while the Camco FasTen 44510 blocks stay the most flexible option and the Lynx Levelers 00015 handle the worst slopes.
Leveling gear is confusing because ramp style levelers, interlocking blocks and stacking pads all solve different problems, and load ratings vary wildly between products that look identical. We compared published load capacities, lift heights and what owners report about cracking under heavy rigs to rank the seven below.
What we recommend
Andersen Hitches Camper Leveler 3604
A curved ramp and matching chock that lets you drive up to any height within its range and stop, with no stacking or guesswork. Setup takes well under a minute once you know your rig. Owners report it is the single biggest time saver in the arrival routine for single axle and tandem trailers.
Pros
- Levels to any height within range without stacking
- Very fast setup compared with block towers
- Doubles as a wheel chock once positioned
Cons
- Only works on tyres, not on jacks or stabilisers
- Grip mats are essential on hard pavement
Camco FasTen 44510 Leveling Blocks
Ten interlocking blocks that snap together in any orientation, so you can build a pad under tyres, jacks or stabilisers as needed. The lock design stops the tower from shifting apart under load. Owners report they are the most generally useful thing in the storage bay because they solve so many different problems.
Pros
- Works under tyres, jacks and stabiliser feet
- Interlocking design resists shifting under load
- Compact and easy to store in a bay
Cons
- Needs stacking and repositioning to get level
- Can crack under very heavy fifth wheel pin weights
Tri-Lynx 00015 Lynx Levelers
The honeycomb pattern locks in every direction and stacks higher than most competing blocks without becoming unstable. Ten blocks give plenty of height for badly sloped sites. Owners report they are the go-to when a site needs more than a couple of inches of correction on one side.
Pros
- Stacks tall while staying stable
- Honeycomb locks in every direction
- Also works as jack pads and stabiliser bases
Cons
- Bulky to store compared with flat pads
- Sharp edges are unkind to bare feet and hands
Beech Lane Camper Leveler
A curved ramp system in the same family as the Andersen, with a slightly wider base that suits heavier tandem axle trailers. It includes rubber grip mats and a carrying bag as standard. Owners report the wider footprint reduces sinking on soft gravel sites.
Pros
- Wider base spreads load on soft ground
- Carry bag and grip mats included
- No stacking or block towers required
Cons
- Bulkier to store than flat block sets
- Tyres must sit fully on the ramp to be safe
Valterra A10-0918 Stackers Leveling Blocks
Ten blocks that nest tightly together, so the whole set takes up markedly less bay space than honeycomb designs. They stack securely under tyres and jack feet. Owners report the nesting shape is the main reason to choose these over the interlocking alternatives.
Pros
- Nests down to a small storage footprint
- Light enough to carry one handed
- Stable under both tyres and jacks
Cons
- Lower load ceiling than heavy duty blocks
- Less grip on wet concrete than ribbed designs
Camco 44573 Curved Leveler
A single piece curved ramp intended for single axle trailers and smaller travel trailers, offering up to four inches of lift without stacking. It is the lightest of the ramp style options here. Owners report it works well for lighter rigs but is not the right tool for a large fifth wheel.
Pros
- Very light and easy to position
- No stacking needed for typical corrections
- Compact enough for small storage bays
Cons
- Load rating rules out heavy fifth wheels
- Single axle focus limits versatility
Homeon Wheels RV Leveling Blocks
A ten block interlocking set with a carry bag, aimed at owners who want a spare set for the second axle or for jack pads without a large outlay. They lock together in the usual grid pattern. Owners report they are adequate for lighter trailers and useful as backup blocks.
Pros
- Sensible as a second set for jack pads
- Carry bag included
- Interlock reliably in a standard grid
Cons
- Lower load tolerance than premium blocks
- Plastic flexes more under heavy static weight
How to pick the right one
Ramp levelers versus stacking blocks Curved ramp levelers let you drive up and stop at whatever height corrects the slope, which removes the stack, reverse, check, repeat cycle entirely. Stacking blocks take longer but work under stabiliser jacks, tongue jacks and landing gear as well as tyres, which ramps cannot do. Most experienced owners eventually carry both, using ramps for side to side leveling and blocks for everything underneath the rig.
Load rating is the spec people skip Quoted ratings vary from a few thousand pounds per pad to forty thousand pounds for a set, and the difference matters most under a fifth wheel landing gear or a heavy tongue jack where load concentrates on a small footprint. Cracked blocks almost always come from putting a point load on a pad rated for a spread tyre load. Check your rig’s gross weight and its axle and pin weights before choosing.
Level side to side first, then front to back The standard sequence is to correct the side to side slope with the tyres still able to roll, then chock the wheels, then use the tongue or landing gear jack to correct front to back. Doing it in the other order means unchocking and rolling a rig that is already partly supported on jacks, which is both slower and less safe.
Protect the pads under your jacks Stabiliser and landing gear feet sink into gravel, dirt and hot asphalt, which undoes your leveling overnight and can leave marks on paved sites. A wide pad or a stack of interlocking blocks under each foot spreads the load and keeps everything where you put it. This is also why many owners carry more blocks than the leveling itself requires.

Common questions
How level does an RV actually need to be?
For sleeping and for doors and drawers behaving, close is good enough. Absorption refrigerators are the strict case, and most manufacturers specify within about three degrees side to side and six degrees front to back. Residential compressor fridges, which are increasingly common, are far more tolerant.
Can I use wood blocks instead?
Plenty of owners do, and treated lumber cut into pads works fine under jacks. The drawbacks are splitting under repeated point loads, absorbing water and getting heavy, and lacking any interlock so towers walk apart. Purpose made blocks are lighter, stack predictably and store more cleanly.
Do curved levelers work on tandem axles?
Yes, but both tyres on the side being lifted must end up supported, which is why the ramps are long enough to carry two wheels on most tandem trailers. Check the specific product’s stated compatibility, since the smaller single axle ramps are not designed for this.
Why do my leveling blocks slide on pavement?
Smooth concrete and asphalt offer very little grip to a plastic ramp, especially when wet. Rubber grip mats under the leveler solve this, and most ramp kits now include them. For stacking blocks, staggering the layers rather than building a perfect column also helps.
Should I put blocks under my stabiliser jacks?
Yes, on anything other than solid pavement. Stabiliser feet have small contact areas and sink into gravel, grass and soft ground over the course of a stay. A block or pad under each foot keeps the rig stable and stops you from having to relevel after a rainy night.
How much lift do most campsites need?
Most sites need two inches or less of correction, and many need nothing at all. Sites requiring four inches or more are uncommon but do exist, which is why carrying a ten block set alongside ramps is worthwhile even if you rarely use the full stack.
Do I still need wheel chocks with a ramp leveler?
The ramp kits include a matching chock that locks the tyre in position on the ramp, and that handles the levelled side. You still need conventional chocks on the wheels that are on the ground, because nothing else is holding the trailer from rolling.
Will leveling blocks damage my tyres?
Not if the tyre sits fully supported across its tread. Problems come from parking with part of the tread hanging off the edge of a block, which puts a sustained pressure line into the sidewall shoulder. Make sure the full contact patch is on the block or ramp before you unhitch.
The verdict
The Andersen Camper Leveler 3604 changes the arrival routine more than any other item here, and for most travel trailers it is the first thing to buy. Pair it with a set of Camco FasTen 44510 blocks for jack pads and awkward sites, and step up to Lynx Levelers 00015 if the campgrounds you use regularly have serious slopes.
