CamcoFasten RV Leveling Blocks - Features Interlocking Design for Customizable Height - Carrying Handle Twists to Secure Blocks for RV Storage - 8.5” x 8.5” x 1”, Yellow, 10-Pack (21022)

Bought these at the start of our camping season. I really prefer these to the ones you drive up on that are like a ramp. Besides leaving out under your wheels they can be used for your stabilizer feet as well or your hitch. Quality is great I have not had one crack, I was worried these would be too big to pull my tires over easily but that wasn’t a problem at all. The size allows you to group them together like legos to do what you need to get level. They come in a bundle with a handle that secures them all together in a nice lightweight block that’s easy to store. I actually bought a second set for my fifth wheel after buying the first set. I got them both on sale and am very very happy with them.

Works exactly as advertised on my tandem axle travel trailer. I read some reviews where customers talked about them cracking on unlevel ground. I alleviate this by placing a piece of plywood down first and then stacking the blocks as needed on top of that. Works like a charm! Easy to store and well made.

As an avid RVer, I can't emphasize enough how the Camco Fasten XL 2x2 Leveling Block has transformed my RVing experience. These leveling blocks are an absolute game-changer, and here's why:Interlocking Design: The interlocking design is ingenious. It allows for effortless customization of the height needed to level my RV, no matter the terrain. These blocks securely fasten together, creating a solid foundation, and there's no need to worry about them shifting or slipping.Stability and Durability: These blocks are incredibly sturdy. They can handle the weight of my RV without flexing or cracking. Even on uneven surfaces, they provide a stable platform, ensuring my RV stays level and secure.Convenience: The Camco Fasten XL blocks are a breeze to use. I appreciate that they come with a built-in handle for easy transportation and storage. Setting them up is quick, saving me time and effort when I arrive at a new campsite.Versatility: They're not limited to leveling alone. I've also used them to support my RV's stabilizer jacks, making them versatile tools for various aspects of RV setup.Quality Build: These blocks are built to last. They can withstand the rigors of outdoor use and are resistant to UV damage. I'm confident that they'll serve me well for many RVing adventures to come.In summary, the Camco Fasten XL 2x2 Leveling Block is an absolute must-have for RVers. They make leveling and stabilizing an RV a breeze and offer peace of mind in any terrain. These blocks have significantly improved my camping experience, and I highly recommend them to fellow RV enthusiasts.

Probably nitpicky to some, but the storage bag came unusable. Zipper crushed and broken and couldn't unzip it even with pliers. Threw it out. 4 stars unless I have a problem with the blocks too. Wasn't the selling point for me, but not a good look either way.

Used for my Scamp Camper. Work well, high quality plastic, stack nicely and transport well.

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.

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.

They are sturdy and easy to stack. I love the fact they stay together for storage.
