I don't have any trouble leaving my bags on the Harley, I strap the rear straps to the rear crash bars and they don't come near the bags... In my current trailer I use one of the cheap Pingle chocks. I mounted it by placing threaded inserts in the floor, and I zip it in with the Dewalt, then zip if back off when not in use. Floor is flat when chock is removed. The only drawback to the pingle chocks is that it takes 2 to load & tie down the bike. I'm going to upgrade to the type that locks the front tire in and holds the bike upright so I can load it and tie it down by myself... Someday...
