A 6 inch or so diagonal stress crack appeared on our brand new (10 day old) RV coming off the bottom corner of the bedroom slide. Is this normal? It looks pretty rough.
I would call the selling dealer and talk to them. Since its only 10 days old this should not have happened and the dealer should know how to handle the problem and get it corrected. Sometimes a little pressure in the wrong spot can cause a stress crack in the fiberglass. Most of the time its in the paint only and not in the fiberglass to say. Again contact the dealer.
