Been lots of discussion on using a Prius as a generator. Ford is now getting serious. Need backup power? Automakers want you to use their vehicles in your driveway | AP News
I remember Ford also offering a vehicle to home charger for the Lightning that would allow automatic switch over during a power outage.
.....welp.....in that case their "Lightning" may be aptly named. In my experience most people who keep their full sized trucks in a garage don't really need full sized trucks - although for the princely sum that they're being charged for a range limited pickup that sucks at towing it might as well be useful for SOMETHING.
