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.
It could happen to a real long coach, but not likely. Long coaches have a tendency of twisting the frame and superstructure of a coach when making steep climbs. I have even seen windshields pop out when you get some brands of coaches in a twisting manner.
