The more you control moister to condensate, the easier it is to control moister build up at the ceiling and windows.
I agree 100%. A motor home is no different than a house. Too many people try to address the visible moisture (simple condensation ... warm moist arm condensing on a cooler surface) when they should be trying to figure out where the moisture is coming from and eliminating it. Best way to get rid of the moisture, ventilate. That is the way a roof system in a house works. A significant byproduct of combustion (burning propane in a furnace, stove, or oven) is moisture. When its cold out, you need to get rid of it. When its 75 to 85 degrees out and the M/H is closed up, you probably don't have a problem. But as soon as you store it and the temp drops to 35, you'll have condensation and possibly mold and mildew.
