In real world examples (places that get hurricanes, for example), the charging stations generally come back online before the gas stations. And an EV is way better in stop-and-go evacuation traffic, too.
> need a super long heavy duty extension cord to power my fridge
Why on earth would you need a heavy duty extension cord for something which pulls so little power?
I otherwise agree with the sentiment, however, it is way more convenient to set up your panel so you can backfeed it to power the whole house (or a nice chunk of it, at least). My Lightning will power all the important bits of my house for the better part of a week, all from the plug in the bed of the truck.
I would need a heavy-duty extension cord because I would have to run it 60 feet from my garage all the way into my kitchen. I also have no idea how I would actually plug the fridge in because the power cord is hidden way in the back.
That it would be more convenient in the long run if I could backfeed to my panel, but almost no EVs in the U.S. are actually capable of this. The F-150 Lightning that you have is quite unique in this regard.
