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!

I too am very happy with our furnace, for several reasons. First of all it is large enough to get the job done.... and then some. Our 24" Nexus Phantom 23P Class C came with a 35,000 BTU - 4 duct furnace. I don't think we have ever had it run for than about 10 to 15 minutes before it was well over 72 degrees throughout the coach.
Another factor for us is how well the Nexus is built/insulated. Once you get it warm it stays that way for quite a while. When camping with sub 30 degree temps leaving the thermostat set at 65 when we go to bed generates about 5 minutes of run time once or twice a night. It's nice to have the thermostat right above my head on the wall where I can reach it while still snug under the covers to toast up the coach in the morning before getting out of bed. :B
Also there are a couple of proactive steps you can take to increase your furnace's efficiency. Hang a curtain or better yet a heavy blanket/quilt between the cab (of a Class C), and the living space of your coach. A windshield cover will also keep the cold out - heat in. Pulling your window shades or using Reflectix (or similar insulation), will also help.
