How long will single battery last with heater running?
We may have our first opportunity to dry camp mid winter for one night. Do I stand a chance of surviving on a single deep cycle 12V battery, or should I just plan on buying my first i2000?

As others have said, it's going to depend, and your mileage may vary.
I've slept plenty comfy at 18-degrees outside with no heater. I had a nice sleeping bag and air mattress directly on the snow. I've also had a heater run multiple nights in a camper with one 12-volt battery.
My point is how warm do you want your camper and how warm do you want to be?
If you have a zero-degree bag you probably won't have to turn on the heater. If you're using bed sheets like you would at home, you're probably going to want it in the sixties or so in the camper/trailer. If it's fifty outside and your camper/trailer is well insulated, your heater won't run much. If it's 18-degrees outside you'll likely kill your battery right away.
So, my thought is if you're married, you should buy a Filson Mackinaw blanket and set the thermostat as low as it will go. Snuggle up close and know it's going to get cold. If it's just you, buy a Butler Bag and don't worry about turning on the furnace at all.
