We recently purchased a 2001 Winnebago Adventurer motor home. When we got it home, and opened it up the very next day, there was a strong odor, the minute we opened the door. We were advised by a friend to get a mold detection kit. We cleaned the motor home from top to bottom an did not find any visible signs of mold. We use the mold detection kit an it showed there was mold present. We got a second kit and it showed the same. We cannot see any signs of mold but these kits say there is mold present. We are not sure what to do next. The smell is gone now so don't know if that had anything to do with our problem or not. Any suggestions??
