Trailer Vented With Furnace On?
DW thinks opening vents or windows with the furnace on will help cut down on condensation. I'd just as soon close it up tight & not lose the heat. Aaaand, discuss....

But warmer air hold more moisture and when it comes in contact with the relatively cooler windows CONDENSATION will form on the windows.
Respiration will increase the humidity of the air
Regular furnaces exhaust all the combustion byproducts, which includes the moisture (hydrocarbons + oxygen = H2O as a major byproduct). Running a furnace adds no additional moisture to the interior air.
RESPIRATION IS THE ANSWER to your question. Ever see your breath on a cold day? What you are seeing is moisture from your breath condensing when it hits something cooler. Your breath comes out about 98 degrees, warmer than the air in your trailer so the it CONDENSES.Every breath adds more condensate of your breath into the air in your rig. It has to be vented.
Same theory applies to submarines and spaceraft but they use scrubbers to lower the moisture
