They are touchy. I saw a guy at Overland Expo mess with his for almost and hour with three people helping him. One of the main problems is that most home built and some of the manufacturers have way too much tongue weight and moving the trailer is almost impossible in the dirt. His problem was that his trailer was headed down hill and the wheels were chocked. The lock and roll is much easier to work with I think. I have tried both and like the new lock and roll much better. Not as quiet by any means. Both do a great job off road, but hooking them up in certain conditions is a pain in the bottom.
