Customer Reviews for VEVOR Trailer Jack Block, 6000 lbs 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

I bought these to help level my 7.5t motorhome. I've tested them a couple of times. They are very solid and can take the weight of my vehicle. They work well with one of Vevor's large leg jacks.
