2010 Winnabago Aspect 30C rear overhang

I have a 2012 28ft I think it is and there is very little clearance with it. I can easily rub going over small bumps. I tried to hang a hose carrier and it was about torn off and this was not far behind the wheels. I would guess the 30 ft would be the same or worse.

I guess you could build a ramp to help get in out of the drive, I have seen tht recommendation a couple of times.
