Does Furnace Run on DC Power??
A friend and I are planning a trip where we might have to stay overnight in a parking lot the first night in. We both have TTs. Can we run our furnaces off of DC Power?

I am fortunate, my 22ft trailer has a ducted furnace that only draws around 4.2A when running. It's an Atwood 8520 20KBTU Unless it is really cold we leave it off at night, I am a light sleeper and it wakes me up even though it is actually very quiet. If we do need it, even using a 40/60 minute duty cycle, for 8hrs only 22.4AH are used. I know most larger trailers have larger furnaces with larger current draws
Yeah, I have the same furnace, it works well. I've stayed out in 30 degree weather for 4 nights on a set of 2GC's with it set at 65. However, an additional complication is that a lot of trailers have a spill duct into the space under the trailer to keep the black and grey tanks from freezing. I don't have this. If you have a trailer like this I'd consider plugging that up so you keep more of your warm air inside. I also keep my bathroom door shut so I'm heating less of the trailer when its cold.
You can't just slow down the fan motor because the same motor is used for the blower as for the exhaust vent.
