If fully charged when you start sleeping, the two deep cycle group 24 batteries (if that is what you have) will safely provide 35-40 useable Ah (70-80 together) before they reach the point that they need to be recharged. Seems to me that this is plenty for your circumstance.

One thing you could do is test if for a night in your driveway before you leave.
Hmm, not sure. It's whatever FR installs as the stock batteries (on a '13). I'll have to go to the storage lot to look.

I have no idea. But I see where I think you're heading. If I was to, say, run the 2 house batteries down, could I then start the generator? The good news is I generally get up in the middle of the night so will glance at the monitor panel to check the charge level. Then start the generator if it's getting low.

We ran our factory group 27's all night with 15 degree OA temps with no problems. This is in our Sunseeker.

If you do run down your house batteries, start the engine. Engine alternator will provide power to house batteries and allow you to start the generator.

Yes, depending on the battery size, charge rate, outside temp, other items using battery and thermostat setting. Lots of variables.

If its only getting down to the low 40s I would turn the furnace completely off before going to bed. Crank the furnace up in the morning, put a pot of coffee on and you'll be toasty warm in no time.

Paul, you will be JUST FINE. We spent quite a few nights in the past few weeks dry camped out in our 2300 in AZ and NM, with some of them down into the 30's. In fact we did it for 7 nights straight at one site, with solar charging during the days, along with some driving around and genset charging. We set the thermostat at 66-68, and for one thing, the furnace didn't run all that much anyway, not until later in the night (early morning hours). For one night, you can do whatever you want.

You have two Group 27 batteries only a year old. No problem. I don't care what the monitor says in the middle of the night, don't start the genset. You'll be fine.

Batt's and the furnace

I would have to say, FR would NOT equip any rig with a furnace, designed for 12vdc operation, if it wouldn't function properly for at least one night. I would be judicial about what other power was used.
