Camco 44527 FasTen XL Heavy-Duty RV Leveling Blocks

These are great for leveling your RV. They are a uniform 1.5 inches thick so that makes them easy to level your trailer. They lock together so if you need to go more than 1.5 inches, you can stack them to get up to 4.5 inches higher. (The manufacturer recommends not going higher than 4.5 inches.) They are light weight, and with the included handle, they stack and can be moved as a group.

Works as advertised. Well built and convenient. I have three packs of these and use them everywhere not just under my leveling jacks. I've even used them to level out a picnic table.

We arrived at a campground in Hot Springs, Arkansas and forgot any kind of blocks for our RV. We got online to walmart and had these delivered within an hour. They worked perfectly to easily get our RV leveled. The store like a dream all stacked and in the compartment under our RV. We would purchase again.

It's a product I've used before and it does what it is supposed to do - raise up one side or another of a trailer/RV to help level it.

Anyone with a RV needs these. Very durable, slide together, takes up little space. You always get a great pitch for draining tanks properly

We needed more of these for a trip that came up quickly. It was so easy to find them on the website, order them and pick them up the next day before we left. The blocks worked just as expected and the trip was a success.

I went with 4 stars because I've only been able to use it once so far. I bought this for the tongue jack of my camper. The ability to take off pieces to get the perfect fit is really nice %26 worked great during my last camping trip. Solid construction and a lot lighter than the 6x6 boards I was using. Definitely recommend this product.

Works great in moderate leveling.. but with major leveling.. and removing trailer from blocks can break blocks base (especially on concrete/asphalt with no give on the ground) but have not found a better option for leveling.

great product, great price (online), store price was 29.00 - online was 21.00, mtn. grove missouri store honored the online price so i bought an additional set. works well with rv jacks 18,000 lbs.

Pros: These stack and store nicely Easy to carry Cons: They break and bend easily, which then makes them un-stackable. I bought these to use on our camping trip down the Denali Highway. We use a truck with over-the-cab camper. After the third night several were already bent and on the fourth night one broke. Now they don't stack together. Disappointing. I'm going back to using lumber scraps.
