What I have learned about cold weather camping . . . . .

We like to use the MH in the winter, and use a 70 pint 120v AC de-humidifier located between the front seats. I have occasionally removed 1-1/2 gallons per day.

I bought a pack of micro-fiber cloths from Costco, and use one or more to wipe down the non-thermal-break aluminum window frames. Dual pane windows help, but it takes about 1/2 hour for the de-humidifier to clear the single pane front windshield.
