Use of combustion equipment
The unvented combustion of appliances, such as a propane stove, are a source of moisture in an RV. For every gallon of fuel consumed, about one gallon of water vapour is evaporated into the air.
Whenever possible, you need to run an exhaust fan in combination with the use of any unvented combustion appliances in the travel trailer.
Water vapour and combustion by-products must be vented out of the trailer. The owner of a RV must follow the instructions for use and maintenance for safe operation of any combustion appliances.
In addition to the dangers of toxic smoke and oxygen depletion which make the use of an oven very dangerous, open flames add moisture to indoor air, creating increased condensation.
