Like maybe a layer of insulating foam material between the metal and the fiberglass exterior and/or interior.
YUP - ever notice the beads of condensation on windows and the metal frames in different circumstances? That, you can see - what you DON'T see, is the same thing happening at various points INSIDE the RV walls - and over time, that can do the same rot and mildew damage as a seam leak...
