Completely agree, Steve. In my case I've rebuilt half of the interior anyway, so don't have any issue with adding the occasional drywall screw here and there to make things tight again. I'm in the process though of converting my popup to a toy hauler, and am considering moving past the traditional ball hitch to one of these swivel types, like Lock-N-Roll or similar. http://www.locknroll.com/
But I'm curious how you actually hook it up- with a receiver essentially on both ends, do I have to do some elaborate docking maneuver? Like on Encounter at Farpoint when Riker had to dock to the saucer section manually... I'm not sure my backing skills are up to that, even with the camera.
