In the case of the F-150, it seems Ford has the numbers to back up that a lot of people would otherwise literally lug generators around with them. For the construction market, I absolutely suspect this feature will be well-used.
I'd like it in an SUV, and I'm willing to bet if offered, folks would jump on it, but I agree it's a lot less likely it'd be heavily used.
Re: Adding another battery, I've considered (and done some napkin math) adding solar panels and a second battery to my car to power the computer I run onboard. But it's something I don't have the time or money to play with right now.
