I have 2 volt golf cart batteries and I'm sure glad. Switch off the condensation switch like facory said and switch to LED lights. But, your furnace if running a lot will draw a lot of power. I have a Mr Heater buddy heater I run sometimes at night when necessary. I keep a window cracked open when I use it. Some will say this is too dangerous to do this. You will have to decide for yourself if you want to take the risk.
I used a Mr. Heater Buddy once and it set off the 02 sensor. To vent the trailer is good but also lets in cold air. I use the furnace if I really have to. If I have electric I use a small portable ceramic heater.
