This is the easiest to use and best chock for holding a trailer in place. You just place it between the tires tighten with the ratchet wrench provided and it holds great.

I have a R-Vision Trail Sport 25S which is an ultra lite, so it moves around pretty good when someone walks around even with standard wheel chocks in place. I purchased 2 of these and they make all the difference in the world, the trailer is rock solid. Excellent product!

We bought two of these chocks. We camp where the sites are not level. It is a lot safer to unhook and hookup plus the rv does not move as much while we are inside. Great product.

You want your RV to not move? You want it to be not stolen? Then you must have one of these X-Chock units! Or two.

I got a pair of these and they work great. Each one comes with a 3/4" wrench and they apply very quickly and securely. Engaging this device takes about 15 seconds and then your camper can not roll. When you are ready to remove them, just back off the nut just enough to pull it out and it is even quicker to put on the next time. You do still have to get down on the ground to install it, but you don't have to worry about mud and dirt that pack into the other kinds of chocks. I think that they are great and I highly recommend this product.

We have one of these and really like it. Totally prevents tire movement. We did only buy one, however, and you should have two. We're ordering the new one today.

This is great. They finally came out with a chock that fits 5th wheels. I would reccomend this to anybody that has a 5th wheel.

My brother bought a set of the original Deluxe Tire Locking Chocks from Camping World. I was impressed with them and also disappointed at the same time. They worked as advertised on his travel trailer but wouldn’t compress enough to fit between the tandems on my fifth wheel. I was very happy when I found that the new X-Chock Tire Locking Chocks would fit between the tandems on my camper. They work great. Thanks both Camping World and BAL!!!

As previous reviewer noted they don't completely elimante movement , but what an improvement. I only bought one set to try and it works great. I am definitely going to get another set for the other side!

We pull our 5th wheel with a class 8 tractor so the fifth wheel is quite a bit stronger then what would be normal for a rv. I needed to be able to really lock up the wheels on our trailer and the elec brakes did not do it.The X chock on both sides let me hook up and unhook with no problems at all. As well as stop most of the movement while camping they are just great.

Very happy with this product. They work very well, and have great holding power. They do not totally eliminate movement in the trailer, but it is greatly reduced. I would definitely recommend these to anyone.
