Propane usage
In mid 20 degree temps at night, only using furnace at night, how long will a 20 lb cylinder last?

How big is your TT/MH? In a small TT it will last most of a week maybe in a 40' MH not so long.

It all depends on which RV you have, how protected from wind you are and a few other things. So, it's almost impossible for us to say how long your cylinder of LP will last.

Each pound of propane has as I remember about 90,000 BTU’s..
If your furnace is 40,000 btu it will burn continuously for about 45 hours on a #20 tank.
The less it is on the longer it lasts.
The hot water heater and fridge burn some as well.

Uhh, I think that maybe you meant a "gallon" of propane has around 90,000 BTU's and not a pound.

Without trying to derail this thread.... we need more information.
1. battery(s) will run down in a day or 2 unless you are plugged into shore power or
run a generator.
2. IF you are plugged into shore power you need an electric heater!!!
3. Read #2 above!!!
4. Everything else.... set furnace thermostat at lowest setting. Get flannel sheets. Get a down comforter or use a down sleeping bag as a comforter.
Good luck!
