Propane duration - Event Date: 15 Nov 2013 - 30 Nov 2013

How cold will it be next week? What temperature do you consider comfortable in the pod. Those questions are rhetorical... just illustrating that without full data, it is impossible to predict propane usage.

However, that being said. Your primary concern will most likely be the battery. I don't know if you can make it more than one night on the battery.   Or do you have two?

But, I could be wrong depending on the cycling of the furnace based on the temperature variables.

The propane itself if you have a full tank should not be a problem. The real problem comes with how long the battery will last and that depends on your thermostat setting and the outside temperature. I think two days at the most unless the temperatures is really mild and you don't use much 12 volts to run lights etc. But I would plan on it lasting one day only. Incidentally I never use the furnace much during the day.

Originally posted by Lefty Thanks for the reply. Only going to use the furnace at night for about 8 hours set on 60 degrees. Will not be using lights at all.

Change your interior lights to LED bulbs. This makes a HUGE difference.

Those temps will reduce your effective battery capacity by 10-15%.  By the time you get to -22 F you loose 50%, temporarily.  This may mean a daily charge is necessary.  If you do use your TV to top-off, hook it up using jumper cables and as someone said, run the engine for 30 minutes.  During the summer I only recommend doing this every other day.

Having dry camped in pa during the winter - 2 Battiries will not last 3 nights without charging them someway.  What I do for a 2 night weekend is make sure the camper is winterirized and carry Gallons of water with me in the camper.  I will run the heater first thing in the morning as I'm getting up and getting ready for the day and also at  night while getting into bed and then turn it as low as it will go during the night.  I sleep in a zero degree bag so I'm nice and warm.  by the end of the second night the batteries are normally empty.   If I need to charge I use jumper cables and my truck running for a while.
