Your furnace runs on 12V DC and propane.
Fan motor is a DC hog so if no AC power available you will need a means of recharging/maintaining battery most likely long before you would run out of propane.
The heat pump will only work when you have AC power....
Space heaters (electric) will only work if you have AC power
Stand alone propane heaters can be dangerous if not properly vented
So use your RV heater set t-stat to that 60*F and turn it on when you go to bed and off when you get up to conserve propane use by heater.
Course w/o AC power fridge and water heater will also consume propane
Just how much propane does your rig have?
1 gallon of propane has 96,000 btu
Multiple that with number of gallons your propane tank holds.....then divide that number by total btu for the total number of hours of propane use.
Example..
96,000 (1 gallon of propane) divided by 20,000 btu furnace (amount furnace would burn in 1 hr) ==== 4.8 total hours per gallon used
Water heater is roughly 10,000 btu/hr
Fridge is roughly 2000 btu/hr
20,000 + 10,000 + 2000 = 32,000 so roughly 3 TOTAL hours of propane use per gallon
11 gallon propane tank..........33 TOTAL Hours of propane use
(BUT none of the appliances burn for full hour so that 11 gallons could last 3 days with just 11 hours of propane use per day)
***Just example....don't know how many gallons of propane your tank holds****
