I have found the answer is a double edged sword. Humidity inside this time of year makes you feel a bit warmer. Yet, when it's -10 outside, like here in MI, the temperature difference is too much. I get out the paper towel also and mop up to protect the oak trim.
My problem is the DW has a large aquarium in the living room and a smaller one elsewhere. As well as having to deal with her green thumb. Plants she brings in for the Winter. TOO MUCH MOISTURE! I bite my tongue and deal with it.
Ventilation, air circulation, proper humidity level is the key. Dehumidifier will help if excessive. Humidity from the bathroom and cooking all play a part. RV windows are not known to be the best.
