We have a 1999 National TropiCal. At the time we bought it we thought all was good. We had a contractor come in to replace the carpet with vinyl flooring. Then all heck took over. He had to reseal all the windows…..we had black mold and mildew under the carpet. A lot of the flooring had to be fixed. My question is he found that the insulation on the under side of the slide was wet. Do we have to get a new slide or can we replace the insulation?? I have many more questions but I will start with this one.
