Lately I have been having an inordinate amount of condensation on the ceiling, on the unit and the outlets to my air conditioners. What am I doing to cause this? I have a 2014 Montana 3850FL.
Condensation forms on cold things in warm air. Your ceiling should not be colder then the inside air (unless you are running the heater). It sounds like you have a duct leak within the ceiling, causing it to be colder then the inside air. Fix the leak(s), and the problem goes away, and the trailer cools better then before.
