Gorilla Tape is one of the best tapes for spun fabric repairs.
The OP was lucky that the steel belts remained intact. When I bought my Starcraft, the drivers side wheel well was missing the top section and the previous tire blowout had spun mud and debris through the kitchen cabinet to cover the load center and sink plumbing.
I replaced the wheel well with a new wood frame and clad the wheel well with high temper steel plate. I used AR300 plate, the stuff they use for garbage compactors and military vehicles. The plate is glued and screwed to the wood frame and sprayed with bed liner. If I have an unnoticed blow out, I won't have to worry about a spinning belt taking out my kitchen or electrical bits.
