X chocks helped stabilize my 238ML. It made it livable without buying an expensive stabilizing system. I've been in sites where one side is up on enough blocks that I don't think one step would work at all. My 2810's axles are too far apart to use my current x-chocks. However, the larger TT seems more stable to start.
