Please help... ? About rear custom fiberglass bumper for TC

Thanks everyone. The bumper plate on my truck is indeed a roll pan. Father In Law had it put on to allow his TC to butt up against the truck since it was so long. I too have a pretty long camper and the center of gravity is pretty far back. So I think I need to keep a roll pan on the truck. I am ordering a new one today. The old one is close to falling off.
