2003 fiberglass TC not looking so good …now what?

^what he said.
although I’m suspecting the OP may not be in the position to do any strenuous work to the camper.
And if not able to maintain and/or cover it (like how the current situation developed) then it will be time and $ wasted to diy or pay someone to sand cut and polish it.
Fwiw, I’ll have about 4 hours here into doing the same on the transom of my 20’ boat.
