I would say the seller's asking price is at the upper end of the going rate, the camper is 25 years old, you have concerns/worries about possible water intrusion and its had a go with a hurricane. My opinion, if it were me, would be to pass. IF this was a "great"deal money wise, then maybe I would really consider it.
I am only on my second truck camper, and learned the hard way on my first. It had water intrusion problems at the overhead vent and was almost impossible to tell from just looking, I wasn't as touchy feely as I should have been and I paid the price.
I would walk away from this one and continue the search, there are more out there and will be plenty more once we get back to what we think of as normal.
