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!

Not only furnace is having low efficiency, but check the construction of your RV.
On my camper I discover that power cable compartment is "cold" one with hole for the cable and non-insulated door. But the compartment had no divider from the space under bathroom sink, where another opening lead to tank compartment with another open connection to the outside.
Such design not only radiate lot of heat, but in case of furnace heating - create chimney effect that runs cold air under shower pan and bathroom vanity.
I used big can of "Great stuff" foam to seal some of those passages and figured out that in case I will camp on snow - stuffing sponges into cable compartment can save me quite a bit of energy.
Than would I have sewer hookup - I don't need to run heat to tanks compartments. New installed gate valve on ducting will allow me to make the choice.
