Insulating windows
I have big problems with condensation on windows camping here in the mountains in spring and fall. I’m trying to find a solution. Is there some way to easily and effectively insulate windows at ni...

I think I've given ventilation a fair try, with little success. Electric heat is not an option because in spring and fall I'm in a Forest Service CG miles from the grid, and generators are not allowed at night due to quiet hours.
I usually keep the interior heat set at 55 during the day and usually off at night. With a vent open and a window cracked by an inch, I'm not sure what else to try in terms of ventilation.
I think 15% relative humidity would be near impossible to achieve here. Right now, it's 34 degrees F and 66% relative humidity outside.
As an example of what I'm dealing with: It's difficult to keep the windows of a vehicle unfogged this time of year around here. Whichever genius at GM decided that in heat or defrost mode the HVAC system in my truck should be programmed to bring in outside air and disallow running the AC compressor below 34* or so, with no override, should be taken out and flogged. I'm bringing in damp outside air and making things worse!
Best solution I've found in the truck is to set it to bi-level AC so I can recirculate the interior air, shut off the dash vents, and wait for the air inside to warm up enough that the relative humidity drops enough to clear the windows. If it is warm enough outside that I can also run the AC compressor, the combination of AC and recirculating is the best way to de-fog the windows. In our other vehicles, I can override to recirculate and run AC compressor in heat/defrost mode, regardless, and they are much easier to keep the windows clear. Just the reality of the cold, damp air around here in springtime.
