I gave up on the idea of the motorcycle hauler, I'll most likely do a trailer. The hitch is welded to the frame and not the bumper so it should be able to tug 300lbs. My other thought is to just tear down the bike and put it inside while traveling, build it up, ride, then tear it down. Not that much extra work and maybe safer. I'm digging this motorhome, easy to drive and did pretty good going up the hill to placerville (sierra nevada area).
