I have a 2002 Holiday Endeavor and am having a problem with an interior trim panel. The panel imediately to the right as you come up the steps when entering gets very cold and sweats when running the dash air. I have removed this panel and put a thin layer of insulation behind it, to no avail. When the dash air is running it gets cold and the trim panel sweats enough that it gets the carpet below quite wet. Has anyone had this problem and what did you do to stop it ?

The best way to reduce or eliminate the sweating is to eliminate the moisture. Warm moist air is coming in contact with the cold interior panel. Can you redirect the cold air somehow? We had the opposite problem once. Camping in the very cold -5 degree conditions condensation froze on the interior aluminum strut locations. The interior walls looked so funny with frost in vertical stripes on the walls.

Is your door shutting air tight? Could warm moist air be coming in from there?

Is there a duct partly off or with a split that is directing cold air at the panel from behind.

OK open the generator door outside and look on the passenger side firewall at the dash air/heat box. On the lower part there is a door that opens when air is taken in from outside. Put your inside controls on Max Air and see if the door outside is closed. If not that is your problem. With that door open you get a build up of condensation that drains inside rather than outside.
On my coach the door hinges got lots of crud accumulated and the door stopped operating. A little silicone spray got it working again. It is vacuum operated.
In the pictures below, the silver ball device is a vacuum motor that operates the door and the door is on either side. In the second picture, the arrows show where silicone was applied.
There is an inlet and an outlet behind the panel but they used the trim panel itself to direct the cold air. Their is no duct behind the panel.
Thanks
Just my shade tree mechanic mind speaking here, but I think this is the problem. If you have air conditioned cold air directly behind the panel I see the cold transferring to the surface of the panel and condensing the moisture. Is it possible to insulate the actual panel itself to keep the cold from migrating outward to the surface?
I know in my stick home, there are two places where the airflow duct is exposed at the duct hangers. During the summer water just drips and drips from those two spots keeping the concrete floor wet just below the spots. I think its the same principle you are experiencing.

Pete: Your idea sounds like it should work but unfortunately I have tried some racecar firewall thin insulation. The trim panel has a channel moulded into it and if I use something thick there wont be enough area for the cold air to travel. It almost seems like there is something missing from the factory. Maybe it was built on a Friday.
Ok, has it always done that? You either have a leak in the system or you have condensation. Those are the only ways you can get water. If a leak, you should be able to determine it has antifreeze in it.
Here are some pictures of the Dash air system that may be of help. A friend had the problem you are experiencing and removed the unit in the generator compartment in order to better insulate the system and eliminate the water.
If the vacuum motor that controls the vent door is not working, it can prevent water from draining thus it will drip inside. With the ignition switch on, turn the controls to AC and look at the position of the vent door. Now turn the control to Max Air and look at the door again. If it is in the same position, the motor is not working or the door is not moving (crud around the hinge areas). Could also be a plugged drain tube. Had a dirt dubber plug mine one time.
Rex: On the inside of the coach on the passenger side under the dash there is a plastic trim panel that has an out croping on it. Behind the panel on the left side there is a hole in the plywood that cold air comes out of, on the right side is another hole that the cold air goes into, traveling through the out croping in the trim panel. Around the back of the trim panel around the out croping there is a sealer. With the cold air traveling through the trim panel and the warm air inside the coach the trim panel sweats and drips on the floor
