motorhome wall heat expansion problem

[vmax1]

In my Dolphin motorhome the bathroom wall goes out about 3/4 inch on a hot day, exposing screws that hold the cabinets, same with the side of the shower, anyone else have this problem? need to find a fix for this, thanks.

Only seen this happen when the weather changed from extreme cold to very warm, crack a window/vent and see if this helps, other wise, I'm at a loss!

I have a 2004 32vs Southwind. I noticed my bathroom wall does the same thing. We were in Lake Havasu Az. two years ago when I noticed this. The wall was facing the sun. When we got back to California it settled down. Now it's doing it again. The motor home sits with that wall facing the morning sun at home. In the afternoon it settles back in. Can't be good for it. My sink cabinet is also loose. Hopefully someone might have a fix for us. Roy
