I believe that I experienced condensation wetness and resulting discoloration in the headliner around the front and rear AC units. I was in Breckenridge Colorado for 3 1/2 weeks with temperatures from a low of 18 degrees to 45 ~ 50 during the sunny days. During the 29 hour drive back to Michigan temps were in the 25 degree range with the Aqua Hot running off the engine coolant heat.
While in the Breckenridge RV site I went through approximately 25 ~ 30 gallons of diesel using the Aqua Hot during the night and early mornings with considerable condensation on the windshield, so there was quite an interior temperature swing during the days. Once back in Michigan and doing the winter preparation, I noticed faint stains on the headliner.
Fortunately, I am able to park the Beaver inside when not being used, however, I have been in the rain a bit without any noticeable leaking in the AC areas, since both units have the discoloration I am currently attributing the wetness to condensation. Thinking about installing some type of insulation under the AC intake cover to prevent warm moist area form going into the unit, and possibly running a dehumidifier while cold weather lodging.
Wondering if anyone else has experienced this situation?
