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....

RESPIRATION IS THE ANSWER to your question.
Mike, you need to get your buzzer fixed. Google is your friend.
People breathe out lots of moisture.
It could be said the additional moisture comes from the human body. The moisture is in the lungs (simplistic model) it is expelled by your respiratory process. You lose moisture as you breathe. This lost has been estimated at 14-15 ounces (400 ML) of water per day. Perspiration will add more moisture up to another 14-15 ounces per day ( you may not even realize you are perspiring). At least that is what I learned in 2 years of taking Anatomy and Physiology at the Health Sciences college I attended. But my professor could have been wrong. The water was inside you and then becomes outside you so I believe that is additional water load into the air. Unless removed from the inside air IT WILL INCREASE THE RH inside the rig. Increased moisture in a given volume of air means increased Relative humidity. As the air is cooler near walls and windows in a rig the moisture will condense onto the cooler surfaces. Cooler air can hold less water so it has to go somewhere hence it condenses onto something cool.
