Furnace fan and battery drain

When we dry camp in cooler weather, the furnace fan is our biggest drain on the batteries.

Short of going without heat, how do you keep the furnace fan from depleting the batteries below 50 percent charge during the night.
  • Ive gotten up at 4 am to run the truck for recharging before. Advantage 4+ gauge wires from alternator to TC house batteries. My other advantage is to turn the truck heater on full hot and blower on high. The truck heat blows into the TC via the passthrough windows. Gets toasty kill the truck after an hour and you should be good till morning.
  • A second battery and a couple hundred watts of solar should take care of that.
