Dripping front Air Conditioner on '08 390bh

I have 2 Air conditioners in my 40' class A. The rear 13.5k btu AC functions fine with no dripping. The front 15k btu AC functions fine but will drip condensation that forms on the interior surfaces of the air conditioner. If I wipe the condensation off and leave the filter and grate off, it will not form condensation. The filter is clean and the AC is left on high cool all the time. Not sure what to do to prevent the condensation from accumulating.

Any suggestions?

About the only thing that you can do to prevent water from condensing on the air conditioner is to camp in the desert. Your best bet is to tilt the rig just enough so that the water runs off in a direction that is least objectionable.

Think OP is talking about the condensation on the INSIDE of the coach.

Put a perforated cover over the skylight to cut down on the heat in the bathroom.

Not on the inside, on the outside. Serves two purposes, cuts down on the heat and is some protection from hail damage, etc.

He has a cool metal duct in contact with warm moist air. If there is room, a thin layer of insulation might help.

Could be foam gasket not tight at ac to roof fit? This allowing outside air to contact very cool duct.
