So open vent and window is pretty much and run heat on the wall instead of mr. buddy and vent shower after usage...cooking run exhaust fan.
WE lived in a 30' 5th wheel trailer with bd room and 13' living area slide for one winter in Oklahoma where in our area we have constant winds and had temps down to just below zero at times.
We tried all the cracking windows/vents...fans to move air around but all that did was create a cold drafty camper with the central heat running 24/7 and burning a 30 gal lp tank every 2 days. Sweat everywhere and was really bad.
Full timers at the local KOA park said to use dehumidifiers. We bought one and it helped so we bought another. No more sweat on the windows/walls/ceiling or in the closets. And we had a warm dry camper after that.
Burning LP inside does create humidity ...as others say use the power vent behind the stove when cooking especially something that requires heating/boiling water.
