Customer Reviews for VEVOR Trailer Jack Block 2721.55kg Capacity per RV Leveling Block, High-quality Polypropylene RV Camper Stabilizer Blocks, RV Travel Accessories Use for Any Tongue Jack, Post, Foot, 5th Wheels, 4-Pack

These are heavy duty and a great price just like everything else vevor makes I highly recommend as a great budget option.

These work great. I have them under the rear 4 legs of my 5th wheel. The wobble has eliminated quite a bit. With 2 people and 4 dogs we were able to feel every step. Not so much any more.

We have used the thin stacking blocks for a long time with our camper. These are so much better. Mostly only need one block per stabilizer and they feel a lot more sturdy with these than the thin plastic ones. They are heavy and solid. The camper feels more stable than it did before. We love them.

These are a great alternative to stacking wood or using the orange Lego blocks. They are very heavy duty and I expect them to perform well. The height seems perfect. I find the least extension I have to do on my stabilizers the more stable my setup is. I can’t wait to try these come camping season. I will be telling all of my camping buddies about these. I did see in the pictures that these can be stacked while in use. When stacked, there is good amount of rotation available between the two blocks. However, I assume that under weight the rotation would be non-existent.
