Original USA Made Strongest Trailer Jack Blocks Stabilizing Pads | Leveling System | Block Stand for RV 5th Wheel Camper, Post, Toungue, Foot (4)

These are much lighter than carrying along boards for support. They are a much better value than some of the other options out there. The only disadvantage, if you were to count it as one, is that they do not have a magnet in them like some of the much more pricey ones. These will stack for more height, adding to their functionality. Being molded plastic of some sort, they are more protective on your hands than boards because there are no splinter possibilities. I have found their stability as good or better than any other supports I have used, but much lighter to carry to the corners of our RV. They couldn't be easier to use, and stack in the pass-thru portion of our RV with ease.

Well built, USA made, heavy duty, appears to be able to support heavy loads and tough use. Heavier built that a leading red brand

I've had these for a year or so and the seem to hold up well. I have no issues and them seem reasonably priced when looking at all the options

Must have bought second set. Better then the yellow squares.

Worked perfect. I even bought 1 1/4" earth magnets and screwed them into the hole on top and now the attach to my leveling pads magnetically before I lower them and are perfectly centered and I dont have to get out of the motorhome to center them. They stay right on the pads with the magnets I purchased.

The strongest and the most durable!

Haven't used them yet, but they sure seem sturdy.

Bought these to stop using wood blocks directly on the ground. They are even stronger than I thought that they would be and have plenty of pad width for the stabilizer jack feet. They are not heavy to position, but also not light weight, perfect? I've had wind blow around the stackable yellow plates before. I recommend this product. I also see they mention you can stack them in use, and from looking at the design in person I don't doubt it. This might come into play if needing to deal with a steeper slope, without having to extend the jacks nearly all the way down. This might come in very handy at some campsites I have seen in the past.
