I didn't think the X-Chocks would completely address the trailer movement, movement by my definition becaused by the wheels moving/rolling. In my original post, I may not have been clear, but the movement I was refering to was the up/down bounce when being walked it. I don't think anything short of a jack to get the weight off of the axle springs on both sides is going to address that part. I still like the X-Chocks mainly because of the way they lock up the wheels and prevent any rolling. It's still very possible for standard wheel chocks to shift. JMHO

I now have a Keystone Outback, but I try to help when I can.
