This highly compact and lightweight direct discharge furnace is just the ticket for smaller trailers. It has a powerful but efficient 12-volt 2.7 amp fan and electronic ignition so you don't have to deal with a a pilot light.
It is a ductless heater, so hot air is blown out the front of the unit and the cold air return is also in the front of the unit. It's just about as simple an installation as you can get in a true furnace.
