I, too, was concerned about the considerable overhang on our 5290 BT Cruiser - 30'6" long on a 208" wheelbase Chevy. To take care of a slight drag exiting our driveway I installed a pair of wheels on the tow bar. Works just fine and assures there's nothing damaged back there.
I believe Chevy's chassis tackles a bunch of issues discussed here. ...ride, push from passing trucks, tail wagging, handling, etc. are just not a problem with this chassis. Love it! Of course you need to take corners a little wider than with a shorter coach.
