F-150 hybrid designed to be "worksite generator"

Apparently no one cares about this idea. Why do I say that? Because GM came out with this probably 10 years ago on their Silverado hybrid. You could pull 120v AC power off of those trucks to power stuff while parked. But, I sure haven't see many people talking about, writing stories about, or using them over the years. It's rare to even see one on the road.
