Good point about fuel use. My Generac uses 1.6 gals/hour. If I have 300 gals of propane and limit the use the generator to 6 hours/day, I have roughly a 30 day supply. If I cut it to 4 hours that goes up to 45 days and so on. The only thing I would use the propane for would be the generator. I have a wood fired furnace and 60 acres of timber for fuel.
