I just purchased a 2008 Fleetwood Utah. The camper looks great except there are some large soft spots on the ceiling. There is an ac unit but the soft spots are not near the ac. They are approximately three feet in front of the ac just above where the screen door is stored. I don’t see any soft spots around the ac. I have read that the ac gasket can cause leaks but could it be somewhere else? What kind of repairs besides the ac gasket should I do?
