Hi,
Most furnaces are a one speed fan which only operates when the thermostat calls for heat.
I did replace the grill with dual window fans--and they do "pressurize" the furnace ducts which keeps my RV from freezing up the plumbing.

I don't know if it was mentioned here earlier, but I just read somewhere that someone put the electric heater next to the intake for the propane forced air furnace and just ran the fan on low to keep the underbelly warmish and inside warm in cold weather. no propane used and seemed like a good idea if you can keep the fan on low.
