RVing in the winter
Hey all, so I'm a month in to living in my RV and loving it, the thing is I want to start roaming around out of Texas and I'm nervous about colder temperatures. There are a few places I want to go to...

Perhaps the key is a second battery. As I understand, the electric blower dragons out within a few short hours without connection to shore power or running the genny.
I'll quote myself : )
The 19G manual states:
HOW IT (FURNACE) OPERATES
Use the wall thermostat to turn the furnace on. Air is heated by burning propane. A blower using 12-volt power from the auxiliary battery circulates the hot air through the motorhome.
WARNING: If the auxiliary battery is not being charged via the chassis engine, a campground connection or the generator, the furnace blower will discharge it in two to three hours and then the furnace will shut off. If this happens, you may recharge the battery by running the chassis engine for about 45 minutes.
I have found the above to be true, running the house battery down -IF- you run the furnace on high. So I don't run the furnace on high.
I'll first warm up the motorhome with the truck engine heater (which also charges the house batteries), then turn the engine off and start the furnace. Once the heater is putting out hot air, I move the thermostat slider down to just above the level where it turns the furnace off. So far, running the furnace this way, the house battery has not been run down overnight. I'll admit that I haven't tried this when it's been really cold, only when it's been slightly below freezing, so my results may be different if I was using my motorhome if it were really cold. In the morning, I'll turn the thermostat up to high, and start the truck up again to help with the heating and recharge the battery.
