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!

Propex makes a quiet 9,553 BTU furnace that is 90 percent efficient, and uses 1.9 amps and 8 ounces of propane per hour when running. It draws combustion air from, and vents exhaust to, the outside. I think one could replace my Suburban 16,000 BTU furnace, and a couple or more of them could be implemented in larger RVs.
