What you need to know is what is the draw in amps for your furnace and any other items you may have on. Then you need to know your battery capacity and also their condition. Realize that a new battery will hold more and discharge longer than a battery near the end of its life. If you start out with decent batteries and you plan on a cool night, not cold but not 78d, and you start off with the rig reasonable warm when you stop for the night and you don't let the rig drop below your comfort setting before starting the heat you will likely be OK. Now if you are heading out in 2d weather and planning on a 12 hour no generator layover, you will probably be in trouble.
