I have racked my brain trying to figure out how to haul the RTT and my dirtbike and so far there is no practical solution. Even in a full size truck the tent would have to be mounted ridiculously high to make it work. I have thought about removing the rear wheel and sliding the rear of the bike under and mounting the bike in backwards, but I would only do that if I was going to load it to get somewhere and load it up to leave--bouncing around from different riding areas while loading and unloading a bike with no wheel would get really old.
A receiver mounted bike carrier is a great solution if you can get away with the decrease departure angle.
