It depends on how long you will be camping, how winter camping works out for you. I use two bottles of propane for 6 nights of heater use. I have solar, so my batteries top-off daily, so the drain on batteries by the furnace fan is not an issue for me, as of yet.

You can stay warm, but if temps are below freezing, your heater will cycle-on frequently. Be sure you have sufficient propane.

This is why we are taking the Mr Heater Buddy along, it uses less propane.
Nether heater is run at night, all lines will be drained as we will use a 2 1/2 gal jug for water. We have been camping when the five gal jugs have frozen.
