Thanks to all for helping. We had virtually no condensation on the windows after cracking a couple windows and the roof vents. We stayed warm for the most part too.
That is all you should need to do based on our experience in cold weather camping. No need for a dehumidifier. We do get a little moisture on the windows when we use a catalytic heater (when dry camping) but we have both a window and a vent opened slightly. We do the same with an electric heater except we we don't usually have the window opened until we make coffee and run the bathroom vent fan on low to vent excessive moisture.
