Baby it's hot outside just about everywhere so we added a dehumidifier to the use of an air conditioner during the daytime. We left our campground for the day for the EAA AirAdventure in Oshkosh with the a/c and the dehumidifier running. When we returned in 10.5 hours and later turned down the bed, there was a 3-foot diameter wet spot on the sheet, fitted sheet mattress pad cover. The top layers of a cotton quilted cover and acrylic blanket were damp but not wet.
This forum continues to be the most active RV forum out there so, even though we are all-aluminum not fiberglass, can you help us solve this Water Spot Caper? If so, here are our clues:
1] In our Livin Lite Camplite 16 DB model, the air conditioner is high on the wall over the foot of the bed; this area is furthest from the door and is located at the front of the trailer on a side wall.
2) No windows
or vents were left open.
3) We set the a/c to 68 degrees on an auto setting.
4) The portable dehumidifier was set at 45% and ran on an auto setting. It was still running when we got back to the campground. The fan continues to run when the humidity reaches the pre-programmed setting. It drains via a pump mechanism through a tube that we run along the floor and terminate on the floor in the shower. The dehumidifier sits on the floor at the back of the trailer next to the bathroom.
5) No other fans were running than that of the a/c and the dehumidifier.
6) It did not rain. The days before and day of this Caper were sunny and clear but verrrry humid!
7) The fan and vent over the front section of the trailer is positioned slightly above the bed. But the moisture was on the top of the bed, not the sides.
8) The exterior cover of the fan/vent on the ceiling broke off the day beforehand. We covered the inside surface with a plastic bag and duct tape (and made a temporary repair to the exterior part of the roof another day). There was no moisture on the tape or plastic and both remained intact
We have a working theory but are baffled as to the condensation (?) that settled on our bed. How could this happen in such a small space with a dehumidifier running?
Dead zone right in the middle of the bed dropping moisture? But why were the outer covers drier?
