The floor of a travel trailer is a composite sandwich of thin metal underneath outside, a framework of odd sized dimensional lumber with blocks of styrofoam insulation fitted between, and covered with a thin ply on the top inside. This is topped with the floor covering, then the shell is placed onto it and nailed in place. Structural weakness in the floor translates to poor support for the entire structure. The floor ties the entire shell to the frame.
My RV had that exact problem. The person I bought it from had neglected to tell me of a former leaky toilet water line that had flooded the underfloor structure while he had it parked unoccupied with water connected. It had destroyed the structural integrity. It wasn't until the entire back end started sagging that I knew there was a problem. Replacing the floor required removing all of the interior and paneling, lifting the entire shell off of the floor with jacks from the outside, and keeping it supported. The old floor was stripped down to the frame, and replaced with all new materials. Then came the fun part of lowering the entire shell back into place and re-attaching it to the new floor. In the process of removing the interior, I found a factory defect in the roof that had caused hidden water damage to ceiling joists and wall studs as well. When fastening down the metal exterior, they had missed one of the ceiling joists with the fastener staples, pulled the staples that missed, then just coated over with a sealer. The sealer had seperated from the metal at the side seam, allowing rainwater to seep through the staple holes. The water pooled in the ceiling above the rear of an overhead cabinet, then it flowed down the wall. I ended up replacing several ceiling joists, and an entire row of wall studs where the water flowing down inside the wall had collected and rotted the bottoms of the studs off. Even after all that repair work, there is more that needed doing. I felt it was just not safe to put on the road as it was, and not cost effective to do any more. I didn't bother putting back most of the lower interior. I did hang some of the overhead cabinets back in place. It's now a henhouse, and those cabinets make excellent nest boxes ;-)
