Selling a unit without disclosing known issues is basically doing the same thing.
True enough, but I was dumbfounded when we traded our fifth wheel and the dealer made the trade in offer, sight unseen. When we went to close the sale and pick up our new TT, the sales guy gave our fifth wheel a cursory walk around inside/out, and that was it. I verbally communicated some problems we were aware of, but he seemed not to care.
To the OP: if the rot is right at the cap/roof deck "interface" that will likely necessitate pulling the cap to properly repair and seal it. A lot of work, and those caps are bulky and heavy. A DIY project maybe if you have somewhere to work on it, the time, tools, and patience. But, definitely a pricey repair at a dealer.
