    Moisture under mattress

    303rls. Anyone noticed moisture under mattress. The side I sleep on is wet between the bottom of the mattress and the plywood base.

    That used to happen with our old trailer, when it was hot out. Haven't noticed it yet on our 303. Try using a plastic mattress protector under your mattress pad and a lighter blanket if you're a hot sleeper. Maybe lay down some floor tiles on the plywood under the bed. That wil help prevent mildew and makes the mattress easier to move while making it.

    The cause is probably condensation.

    See this previous thread on the subject:

    You could also try a small dehumidifier.
