Ripple in fiberglass on corner

[Eaglechief_13]

2012 Whitehawk. Just got it out of enclosed storage yesterday and notice rippling on the side upper corner where the side meets the trim for the back. The ripple is probably about 12" along the corner molding and maybe 2 - 3" wide. Not bad, but noticed while inpecting after storage.

Everything seems solid, no signs of structural issues, no signs of water leak. Any thoughts?

I’d put my money on a water leak. Check the caulking where the rubber roof meets the trim and side wall. Your unit is now 9-10 years old and long over due for new caulk

Water leaks will cause this, but I am not so sure seeing it was stored in an enclosed location. Perhaps a picture would help. I have a few small ripples in mine but not noticeable unless the sun hits it just right, and I have no leaks. ~CA

+1; water leak. The fiberglass is starting to delaminate.

Water can come from a lot of places. One spot many people don't check is marker lights. You may have a few screws along the gutter that needs to be caulked.
