One note, open a bath roof vent or something. A by product of LP burning is water vapor and will drive up the humidity in your RV.
No need to open a vent. Running a furnace does not produce water vapor inside the trailer.
Yes it does. We must run a 30 QT dehumidifier with the heater on or watch the water slide down the glass onto the walls. We don't open a vent.
well, the water is NOT coming from the furnace or you have a real safety problem. the furnace or WH combustion is seperated from the inside venting. Same as a house, it goes up the vent stack. so NO water vapor goes into the living area. If combustion air is exhausted into the living area CO poisoning is a REAL possiblity.
Now the stove/oven will emit water vapor into the living area, but NOT the furnace or HWH.
What you are likely experiencing is air circulation from the furnace fan causing air near the dew point to hit the windows, and then condensing.
Unvented cat heater stove/oven another story. They do put water vapor inside the trailer. Slightly less than gallon of water for every gallon of propane burned.
