I agree too. Doesn't remove all movement, but a great deal of it. Terry has posted a couple of times about his trailer rolling, but i just can't see it. Mine sure seem too tight for that to happen. Not calling you out, Terry, just don't see how it would happen, based on what I've seen. :)

Just for kicks try pulling away with your X chocks in place and see how well they keep the trailer from moving vs. using ground wedges.
They work well for stability but they are not designed to keep trailer from rolling.

Well, I guess if I've got to hitch up and pull with my truck to get the trailer to roll with the x-locks applied, I'll still feel ok about it not moving when they're applied on level ground and not being tugged. I'm referring to "properly applied", and I doubt that driving away with them between the wheels would qualify. ;)

It's all about friction. If the slope is great enough, or if enough force is apply the trailer will roll. You will not be able to drive off with ground chocks in place. They are 100% fool proof.
X chocks will allow rig to roll without much effort. People accidently drive off with them in place all the time,however you cannot accidently drive off with ground wedges in place.

I hope it doesn't happen often but I have read accounts of trailers rolling.Some were using X chocks.
The bigger point is the designers of the X chocks state you should use ground wedges in addition to the X chocks. Of course there are always consumers that know more about a product then the people that made it.
