Furnaces. Very inefficient!
Seems to me that the furnaces in rv's are patheticly inefficient. There are natural gas house furnaces that are so good that the exhausts are plastic!

For one thing, it seems like those RV furnaces draw combustion air from the surrounding space. If that space is open to the inside of the RV, cabin air is drawn out through the stack and replacement air comes in from somewhere.
Both Atwood and Suburban RV furnaces draw their combustion air from outside of the vehicle as well as exhausting it outside. Internal air is drawn thru a cold air return for the heat exchanger and sent back out the heat registers, just like most residential hot air furnaces.
