We have a 2007 Rockwood Ultra Lite fifth wheel.
In the bedroom on the front side just couple inches past the window to the front.
Found very soft spot in the wall so I opened it up.
What had deteriorated that looked like nothing more than particle board a strip from top to bottom about 4 inches wide
Then on each side that look normal was the white styrofoam my question is why would there be particle board strip from top to bottom just in that spot?
