Fully charge the battery.
That's what I wonder. The furnace is the biggest draw of those mentioned, but shouldn't kill a fully charged battery in just one nights use.
Depending on the outside temp, yes it will. When dry camping in Yellowstone in September, we learned that the furnace could not be set much above 50 degrees or the batteries would run down about 2am. And we had a pair of group 31 batteries.
With the heat set at 50, we could go 2 nights for sure. We may have been able to go 3, but didn't push it.
