I ordered this thinking it would prevent my trailer from rolling off the leveling devices. The instruction explicitly state not to use them for that purpose. Probably my fault for not reading all the info thoughly. Sent it back.

These chocks are great for just a little more stabilization. We have a large popup camper (Rockwood HW296) and it's fairly unstable with the stabilizers alone. These chocks add just enough stability that the camper feels solid. I bought one for each side and they ratchet on and off with ease. The included wrench works great and makes quick applications a breeze.

Almost bought the cheap plastics ones. Glad I didn't. These are built like tanks. Will last for decades.

My trailer never felt so stable, especially at night when everyone is sleeping, I didn't feel anyone's tossing and turning as I did in the pass.

Do it! Don't even think twice about it, just hit that yellow add to cart button and impatiently wait for them to come home! My only problem with them is I didn't get them sooner and had a few trips wobbly camping trips (not from drinking wobbly pops either)! They lock the trailer down and make it so solid. My trailer is a little higher off the ground and my landing gear/stabilizer jacks get extended down pretty far. My trailer moved so much and these wedges I tried didn't work. I was worried that we were going to end up buckling the stabilizer jacks when the trailer was...well, when it was in use! These things changed my life. I am now much younger, better looking, and have all the best stuff that money can buy! Well, I have the best tire locking chocks that money can buy...the other stuff I kind of made up. Hey, Don't judge! Haaha, fun little moment and hopefully made you smile. It really is a great product and I really do love the quality, the simplicity and ease, and especially how well the work! Oh, make sure you get one for each side. I'm glad I remembered that part. I almost ruined lives!
