Dometic / Atwood DFSD12111 RV Mojave Propane Heater / Furnace - 12K

Atwood has redesigned their Forced Air Propane Furnace. The new furnace features a new heat exchanger, radius tubing for quiet operation, improved airflow, and a lighter build. This furnace can be positioned in several different ways, making it the easiest furnace to install in a van conversion, small trailer, truck camper, or even an ice fish house.

Innovative heat exchanger

The one-piece tubular design eliminates seams and welding for a more robust heat exchanger that maximizes air distribution. The radius tubing allows the air to move more freely through and around the heat exchanger. Reduced air turbulence means a quieter furnace.


Don't worry about making your furnace fit one way, this furnace can be mounted horizontally or vertically. With several duct configurations to choose from, you can make your cabinet the way you want.


This unit is typically installed in tent campers, truck campers and small travel trailers due to its small size and lower BTU capacities. Recently it has been popular in custom van conversions and ice fish houses. It is sometimes used in larger trailers or motor homes for smaller zone heating.
