Delamination is a problem with a lot of the fiberglass campers both motorhomes, 5th wheel and pull behind campers. Yes it is a cosmetic situation when first noticed however can become a problem later. It also will be difficult if you want to sell or trade up. The problem is with the manufacture's and thier inability to recognize what they are doing wrong and not having the knowledge to correct it. If its under warranty they simply replace whatever side is the problem. I had a new 5th wheel that the dealer sent back to the factory to have one side and front and back replaced. When we got it back, with poor workmanship, we got rid of it as fast as we could. Went out for older 05 Holiday Rambler that has better quality, being older. Newer campers look very fancy but fancy does not hold them together. If I was looking at a new camper I would take my time and go over it with a fine tooth comb. Sorry to put this out but it's time to clean up another industry! New isn't always best and sometimes we oldies know more than you think!
