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 a must for leveling your camper without dragging around cinder blocks or sloppy jack blocks that fall apart and create a headache in the storage area!
I bought these for a 6000 lbs 30 ft camper and they have worked great for months. No issues, heavy duty, they slide together and save space for storage.
These blocks are heavy duty but lightweight. They are the perfect height for the stabilizers and can stack, if necessary, for the tongue jack. And they are reasonably priced. I highly recommend them.
