My overhead bunk mattress was damp with mold. Searched everwhere for the leak.
Turned out to be dampness formed by warmer underside of the mattress meeting the coolness of the cab directly underneath.
Installed a insulating styrofoam board under mattress which helped plenty.
May not be the case here but worth mentioning in case someone else may wonder whats up with the moldy underside of mattress.
When occupying any unit, you always need to provide interior ventilation, especially when sleeping because you aspirate moisture when you occupy any unit.
I know it sounds counter productive to have windows open when it's hot out or cold out, but it's necessary. An RV unlike a house is pretty well sealed up from ingress and egress of air. You have to allow for ventilation at all times.
Condensation will collect on a colder surface, just like a cold glass of water collects moisture from the air on the outside of the glass.
