Condensation and Roof Construction Concerns
Hi folks. I'm seeking info from you guys who've been doing this a while. This is my second winter in our FW as a camp host in northern Louisiana. I don't remember seeing any condesation last winter bu...

Hi klawklr,
Cracking a window. The idea is that hot moist air rises drawing in cool air. As the cool air warms it drops the relative humidity inside the RV. I would relocate the electric heater to where the air is coming in. You can experiment with the size of the openings needed. Make a crude draft gauge from a piece of Kleenex. Use the roof vent to control the amount of air flow while measuring the draft at the window.
I am full timing in a class C. Right now the temperature is -7 C (19 f) and the low is forecast to be -10 C (14 f)
I've used my RV at -37 C (-34 f) and have boondocked for 5 days where the high was -27 C (-16.6f)

Hi,
Crack a roof vent and open the window (a bit) that is farthest from it. Place one of the electric heaters near the window.
Condensation is about keeping the surfaces above the dew point temperature. I have been known to run a humidifier inside my class C in winter time, but I live in the North American equivalent of Siberia.
Thanks Don, I have opened the bathroom vent about 1.5 inches. Are you suggesting cracking a window farthest from that vent? Or cracking a roof vent, say, in the living area and cracking a window in the bedroom which would be farthest from the roof vent? I would suppose then I should relocate an elec heater to the bedroom where the window is cracked? Are you using your class C in winter time?
