^^^ Agree. Except on sloping ground you don't want to rely on just these alone.
X-chocks are all we use but we're always on a level site in a CG and at home. I've rolled into a CG with the tires heated up, installed the X-chocks and had the temps go down below freezing overnight and the X-chocks have
not loosened up. They never loosen up with a swing in temp but I cinch them up tight. I think the CYA is there because there is no way you can specify how to torque the X-chocks up enough so that every trailer owner will get them tight enough.
Chocks are for not only to prevent/resist a trailer from rolling away, you want to minimize fore/aft motion and the X-chocks do an great job of that. On sloping sites, use something in addition to or instead of the X-chocks.
Most important thing of all is to make sure you have some kind of chocks in place before you unhook the chains and don't let anyone distract you. X-chocks will pop out if you pull forward with them still in, but you will also run over other types of chocks.
