We just brought a 2012 Viewfinder 19FK from an elevation of 4500 feet to 8500 feet, then back to 5500 feet, in high southwest temperatures. This was over a two-day period. When home, I found a round area of about 1.5 feet where the Fiberglas had bubbled. It is not crazed or cracked. I am concerned that it may not deflate and that the stress on the fIberglas will result in a leaky break. Any words of advice or experiences like this to share? Thanks much.

Where is it exactly - front, back, side?

Driver side, about a foot from a window, at about 4 o’clock...

Sounds like delamination. The trip probably had nothing to do with it, other than causing it to show up now. Likely road vibration and weakened glue just let go.

Sorry but you just lost thousands in resale value!Delamin8is most of caused by moisture in the Luan behind the fiberglas! Maybe a minor leak around the window.I will not buy an RV with WOOD backed fiberglas!

Seals and caulk need to be checked and maintained a couple times a year, something very few owners do until bad things start happening. The they 'reactive' instead of being pro active.
