electric space heater

If freezing out, leaving the furnace on low to avoid freezing water system may not work if you are heating the camper with elec. heater. Furnace won't kick in and then the underbelly won't get any heat - if your heat system includes heating the water storage/pipes areas.
We use the low furnace setting for when we are in transit during freezing temps.

I can only go so long listening to the loud blower motor noise with the built-in furnace.

ALso we always plug-in our portable electric heaters to the camp ground pedestal 20AMP service using a drop cord. Better to use their electric verses my propane to run the furnace. I never shut down the furnace but set it to low setting as the built-in furnace does provide heat thru the underbelly area to keep the tanks warmed up some when it gets really cold.

My AF 990 has a fan which circulates warm air thru the basement whenever the furnace is on. I wanted to be able to power the fan when using the space heater in addition to having the furnace control it.

I installed a White-Rodgers digital thermostat which has a Fan switch. There is a third wire coming to the Tstat which controls the basement fan. When I removed the original Tstat I moved the "third" wire to a terminal on the Tstat which allows me to switch the basement fan on/off manually. It still comes on automatically whenever the main furnace kicks on.

This worked well at -18 degrees last November in Idaho. Nothing froze!
