Guys I need help. We looked at a used 1999 Rexwell today that had a bulge down the side. Otherwise the coach is in great shape. My wife really likes it and wants me to purchase it. The wall is firm when I push and pull on it and the roof is excellent.

Is this a show stopper? I have pictures but not sure how to upload.
