It depends on your use case. If your use case is emergency backup power, then yeah the truck is the hands down winner. But if your use case is to load shift to minimize costs then buying a slightly smaller fixed location (ie: powerwall) battery bank which is always able to be on-line will likely make more sense, since once you drive the truck somewhere it's no longer attached to the house.

It depends on how your electricity generation, distribution, and consumption works for your own location.

But also, holy cow! $130k in powerwalls is a LOT of powerwall!

Natural gas and/or propane is the best option for my home. Solar installation + battery is just insanely expensive compared to gas (6x at a minimum) and where I live offers far less reliability.

I agree. Plus any prolonged power outage (multi days) is likely to be area wide which means that topping up an F150 from a fast charger before dark and those are likely to be heavilly over subscribed (or out of action) in the local area.

With the Powerwall option you could top up your F150 at home then range further to find a working fast charger thats within the calculated power budget.
