recently opened mine and found dinete booth cushions wet. Took cover off air conditioner inside and found 4 bolts loose and gasket not compressed. I tightened the 4 bolts equally to compress the gasket about 50% and have had no more leaks,Mine only required drying the cushions and wood under seats I had no mold except what was on the inside of the canvas when I purchased it. I bought some RV mold remover at Walmart and followed directions and was able to clean it all up and it has not returned. Hope this helps.
