some folks must not breath out or perspire much water that a simple "cracked" window lets out their moisture.
Just myself in 15-20°F weather, I can leave the large window full open and roof vent full open and still have condensation rolling off all the other windows and metal door frame. Bring in the dog and the humidity level gets down right tropical.
If I'm camped where there's a plug, the dehum. runs 24x7. If I'm camping on battery, things get tricky; a single 2000 watt genny isn't enough to run the dehum and my battery charger at the same time. if I'm running two 2kw genny, no problem aside from the noise of two genny.
