[Brantlaker]

I would check the clearance lite on the outside for a leak. if it is leaking the water will fallow the wires through the wall (wall sits on the floor). I had the same thing happen to me last to me. I leave my 5th wheel in Florida for the Summer and came back to a flood in the back of my rig had to replace carpeting and trim repaired the floor with Get-Rot a Marine product for wooden boats. I thinned it out and brushed it on it will soak into the wood and make it hard and dry.
