Camco Camper/RV Leveling Blocks - Features Stackable Interlocking Design & Includes Zippered Bag for RV Storage - Compatible w/Single Wheels, Dual Wheels, Tandem Axles & More - 4-Pack (44501)

I've tried several different types of levelers for my trailer and always end up going back to these stackable blocks. They just work, they're lightweight, they link together pretty securely, and they don't rot like wooden planks. I have several packs of these - we've stayed in some pretty un-level campsites - and just ordered this 4-pack to use under my tongue jack because I lost the wooden block I was using.Short of spending a fortune to install hydraulic levelers, these Camco blocks are the best solution for leveling your camper. My suggestion is to buy more than you think you need, especially if you have two axles on your trailer - I have used two 10-packs on one occasion. A 10-pack is good for about 4 inches of height for a single axle - for a 2-axle trailer you'll need 18 to 20 to get that same 4 inches of lift.

so far so good. i’ve read other reviews about negative experiences. sounds like they did not use these on solid level ground. they have worked well for me on concrete. helped me level so my rv, so that my fridge will work.

These have proven very helpful for the purposes that I bought them for. One is to lift the front of my SUV a tad to make it easier to get beneath it for oil changes. There is just enough room as it is, but that extra +/- 2" just makes it that much easier to maneuver.Always use chocks and set the parking brake. Use jack stands if the vehicle's standard clearance would be at a crushing level and be mindful of any incline in the terrain. This can be more significant than is apparent.These are also useful when washing the vehicles tires. Otherwise it's difficult to next to impossible to get to the bottom edges of the tire that is sitting on the ground. We've all seen wheels that were cleaned with that one glaring strip that could not be reached for cleaning and tire gel that sticks out like a sore thumb.I am confident that these will perform well for my 17' tandem cargo trailer's tires and tongue jack, and same with my 19' travel trailer, both dual axle, though leveling blocks made for tandem tires would be a bit easier to use in lifting one side up a bit or protecting the tires from cement.One would also have to expect a certain amount of distortion if these are left under weight for extended periods. I see comments on people using wood, which is fine to keep tire contact off of cement, but wood splinters and cracks, so should never be used under a tongue jack if needed to secure the trailer at a height sufficient to maneuver the hitch ball beneath it.I read about these being crushed under a Class "A" RV-that is expecting these relatively inexpensive units to hold the stabilizing pressure of a bus. Others had similar but stories but failed to say what kind of rig that they attempted to use these under, nor did any mention the degree of incline that they were attempting to compensate for.Declaring "not for use with levelers" is an absurd exaggeration without specifics. "Not for use with a bus sized RV, on an incline, with slide outs extended" is one thing. Take a look at the grade of leveler used for demonstration, then look at the footprint of the huge hydraulic pad that this reviewer provided in her photograph, then look at her sweeping statement "since it did not work on my behemoth, it will not work under any circumstances, including your pop up camper!".Use some common sense here. These are built like large Legos. Look a the images provided for an idea of what kind of support that these are intended to provide. "Heavy Duty" is a relative term used in marketing that means nothing if no context is provided. Camco should be a bit more specific, but customers also need to use some common sense and exercise a bit of due diligence.

Update: once I got over the shock of the change and got a chance to use the hollow/see-through versions on a few trips, I have to admit that I actually like them better than the solid ones. The bottom one on the stack will definitely sink in somewhat on really wet ground, but the hollow design keeps them from holding water; no more holding the stack upside down to let the water run out or having to take it apart to empty each one. I am changing my original rating from 2 to 4+ stars.I previously bought these a couple years back (two packs) for my work trailer, a 32-Ft bumper-pull toy hauler, and have been very happy with them. They get used five days a week for everything from jack supports to extra steps with no issues. They are typically used on pavement but are occasionally on grass/gravel. I recently bought a personal camper so I used the same link from my previous orders; imagine my surprise when they arrived and I realized they were no longer a solid piece of plastic! All the holes makes them worthless on soft ground without something else under them; my lighter personal trailer pushed them almost completely into the ground!! Please go back to making them solid…I need a second set but won’t buy them like this again.

Have been using the same pack of Lynx Levelers for 25 years. As they are largely open space, they get brittle with age and crack. Bought a pack of these to add on, because you can never have too many leveling blocks. They are more solid and a less brittle plastic. The only disadvantage is that it is harder to dislodge stuck stones to pack them back up because there are no holes to poke through. It's great having a bag of each now.

Easy to use and fast delivery. Held up to 10k trailer

Very sturdy, light weight and stores nicely in the bag

What can you say there blocks. Works good

Work as expected.

Me han sorprendido, las utilice para colocar un gato eléctrico de 5T y levantó sin problemas una Ford Lobo. Muy resistentes. Muy importante como las coloques

These blocks are well designed strong yet light weight. They are quite easy to store because of the number of pieces and shape. We really like ours and would recommend them. We have a class B motor home so storage is a big issue.
