Don't have much to do with the above but for interest sake... increasing the air temperature 20degrees F doubles it's capability to hold moisture.
Ex: 100% moisture in 50 degree air heated to 70 degrees = 50% moisture. Works the other way too.. 70*F at 50% humidity cooled to 50*F = 100% humidity.
Learned this when working with ventilation systems in 500ft long chicken houses. Not knowing this can kill thousands of birds in a short time and rust cables supporting the feeding system. Couple growers I know learned the hard and expensive way thinking they would save money one winter.
I suppose that would explain all the moisture at the windows of a camper too.
