If the motorhome is sealed shut it seems unavoidable at times. If could keep a vent open and draw a small amount of air through it, that would move some of the air through the coach and reduce the percentage of moisture content. The condensation that you see is all due to temperature difference and heat absorption of the humidity in the coach which gets deposited on the windshields and glass. To a lesser degree you are also going to experience this event in places that you can't see like behind cabinets and inside of cupboards. It's always a good idea to vent as much as possible when living in your RV.

DriVer is correct. If you open your vent on top and crack a window just 1/8 " you will elliminate most of the wetness. This will cause you to spend more money on heat.

I found a method that really helps a lot with the front windshield condensation.

I start off with a windshield thermal foil (very nice from Camping World: Large: $20.00) with 3" opening at the bottom. The thermo shield works well for heat and cold insulation.

I have two small (very small 3" fan) fans blowing on the windshield 24x7 (one fan on the far left side blowing right) and one in the center blowing right) plus absorbent cloths cut into strips sized to fit across the bottom. As the fans blow across the bottom of the winshield (they really help a lot), the cloth strips pick up any excess water running down. The fans continually dry the cloths along the bottom of the windshield throughout the day.

Someone I know in the park just had an external windshield canvas cover custom installed with snaps to prevent inside windshield condensation. You've probably seen these. The canvass completely cover the entire outside windshield with button snaps to attach.

How about running a small, room de-humidifier? Wouldn't that help?
