Very common and you'll see it on a lot of coaches. Mine is NO exception. It's been painted twice by the factory to no avail. That last quote I had was $1800 by an independent paint shop in IN. The factory wanted $3200. No way is that going to happen. The factory says, "you don't wax it enough" LOL I told them especialy when I'm up on a ladder in that situation I go overboard to take care of the hard to reach areas. Another question I had was why then is the sides and rear on the lower portion of the coach not peeling????? Their answer, "it's not in the sun as much". LOL again. The only thing I can add is it's plain poor workmanship.
