Waves in fiberglass

I have developed some waves in the body of my grand Villa. I am absolutely certain they were not there when I purchased the rig, and other than driving it a couple hundred miles home, it has not been used. It is just been sitting in the driveway with no water hooked up. This side of the rig has been getting pounded by sun for the last six months or so and that's the only thing that I think could have caused this. The fiberglass feels solid still, it doesn't feel like it's separating or spongy. It's just warped. Anyone know what's going on?

Sound the FG side where you see the outlines of the box beams.  Likely the adhesive has let loose.

Elliott, what's inside the coach in that area?  I had some similar waviness after that side sat in the sun for a few months...shower wasn't caulked properly and moisture caused the delam only in that area directly behind the shower.  A. year after recaulking the shower walls and pan, the waves have practically disappeared.  Hope yours is that simple.

It is in fact the shower just like you suggest. Now that the sun is off of that side of the coach, They are much less noticeable. One of the first things we did was go in there and recalked everything when we got the coach because it wasn't moisture tight.
