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.
While I would be upset if my new motorhome had that crack I have had that identical crack in my 2003 Bounder turbo diesel and other having to keep it sealed I have had no problems and it hasn't moved in six years . I didn't notice it until I had the motorhome a couple of years. When I had it in for service the mechanic suggested I keep it sealed and it sure seemed to work.
