I would use a generator, because although
batteries may power the radio, you still
gotta eat, keep your coffee maker, freezers, refrigerators,
range, hot water, well pump, lights, heat/AC,
etc running to produce a well fed and
comfortable operator to continue operations.
Alos, in my case, my OES duties require that I
be able to use most all of my radios, my FAX
and computer network. Lot to ask of batteries.
I don't know about MOGAS storage in NC,
because I don't have any stored here.
Howerver, I use propane for my generator and
have a tank of sufficient size to run the
house for 5-6 days according to the calculations.
I've never been without power for more tha 4
days and I still had some left. Of course,
after a long outage, you need to promptly
refill. Exercise the generator weekly, too.
