No doubt keeping the total weight and height low will help. Having said that, the biggest problem to overcome are weight distribution, and bending stresses on the frame. This last part gets unmanageable when the motorhome already has a long rear frame extension.

For example, while my van is much smaller than the two Coachmen in the pictures above, the rear orverhang is much shorter, which helps a lot. Adding a 1,000-pound load behind my rear bumper will only unload front wheels by 500 pounds, so rear axle will see an extra load of 1,500 pounds. In my case that's well within axle and tire load ratings.

I'd expect that in most Class Cs adding a 1,000-pound load (motorcycle plus carrier) behind bumper would overload rear axle and/or tires. I'd also expect frame rails could get stressed too high because of the long moment arm. Handling would likely be unacceptable also. These things can't be seen on a picture of a parked motorhome.
