I am new to the world of camping with a fifth wheel. I am wondering about my propane heater. It blows hot air like a champ when i have electric hooked up for the fan motor to run. My question is, when I am in the woods without an electric hook up, can I still run the heater with out a blower fan? Do I need a generator to run to the heater fan? Anyway, thanks for the tips. Corey
