? about boondocking with furnace

The condition of your house battery(s) also determines how long the furnace blower can run before battery(s) become discharged. An old/poorly maintained battery may only last for 4 hours of off/on furnace blower operation. When your house battery is near dead, your 12 volt DC appliance controls on fridge etc. may not work and your generator won't start unless you have the truck engine running and charging your batteries.

Yes, the problem snow-balls with the fridge dying overnight and no way to start the generator until the batteries get recharged by the chassis engine or shore/pole power. It is not a good situation to put yourself into so make sure your batteries are charged up before going to sleep.....or set your thermostat way way (way) down.
