Tj and 2 motorcycles on a car hauler behind camper.

With a 10 or 11 foot camper there will be approx 3 or more feet rear over hang.
You go running the trailer tongue under that wont it hit when the front of the truck go's up before the trailer? I cant see how it wont. Going up even a minor incline would cause some serious damage I would think. Like having a fifth wheel with not enough bed clearance.
