Water damage, most RVers biggest fear. I know it's mine. Unfortunately, when you find out about it, the damage is often severe. They don't call it "fall- apart-icle board" for nothing. I would try to fix it myself if I were you. Try to enlist the help of a friend with good carpentry skills if you can.
