The all-electric house is something I don't have to worry about. We've got gas heat/stove/water heater and are in town so gas disruptions are realistically unheard of. I've got a 5kw/6.5kw start Ryobi I picked up when my old Coleman quit again. I manually cut the main breaker and have a cord to backfeed the system through my welder plug. The garage is detached, so I block the door open 6" and run it in there since it is a bit loud when the rest of the neighborhood is quiet. It'll run the whole house, winter or summer. I drain the tank every spring and put the fuel in my truck, then keep 5 gallons of treated gas around for that and the mowers. I've got an 80 gallon diesel step-tank I picked up from a semi-truck upfitter that's my plan for a long-term outage. I've got friends with 500 gallon farm tanks that I can hit up if all of the stations are closed...
