I agree I need to find the leak. Perhaps after all the rain that we had locally some found its way in.
The Draws are located below, and along the side of the closet in the rear of the TT. I looked into the closet above/beside it and no water no mold. Next I am going to get on top and look at the seam between the end cap and the roof. Within the last 2 years I did apply eternal bond. Have never had any issues with it and have had it on for a total of 10 years or so.
Maybe water has come in through the tail or clearance light up top?
