The Ford F150 Powerboost has an optional 7.2 kVA inverter, which I am not sure if there are any other vehicles that can do the same off a gas tank.
I am guessing that one of the use cases is a support unit to charge an EV just enough to get it to a charging station.
Ford has had options like this forever and it's usually targeted at farmers and ranchers, I think the first I've found was like a 77 or 78 f250 'rancher' that had a generator option on the main belt off the motor. The ads show a guy cutting boards with a skill saw to mend a fence or something.
edit: I think these also had a ford branded chainsaw over the wheel well on the other side of the engine bay.
Had to look this up, not great pics but very cool:
"The generator was called the Electric Power Pak. From 1969 to 1972, Ford offered a 2,500-watt underhood generator, mostly on the Contractor’s Special, though it could be special ordered on other trucks. It also wasn’t driven off the engine’s belt. It was a separate Onan generator with its own 5.5 hp air-cooled single-cylinder engine, feeding an outlet in the bed. It sat on the driver’s side splash pan. The package the commenter calls a “Rancher” is likely the Farm & Ranch Special, which is one of the trucks that came with it.
The chainsaw was real. Ford sold Ford-blue chainsaws from 1970 to about 1976. They were rebadged Ohlsson & Rice saws: the Eagle I/II and the smaller Hawk. A mount was also sold that held the saw on the F-250’s driver’s side inner fender"

Nice find. It's been a long time since I've seen these so I did get some details wrong =/
I was actually quite impressed by how well you described a 50+ year old product and ad, a commendable recollection in my view
I have one, and I have powered my house with it on a few occasions. I made the purchase after a friend of mine ran his for four days straight. I always fill up the tank if there are storms coming.
When I was shopping in 2025, this was the only truck with that kind of output.
I almost purchased that truck, but I needed a higher cargo capacity for my travel trailer, and the added batteries reduced it by 250lbs or so. The ability to plug a travel trailer directly into the truck and run it is really cool.
2024 and later Toyota Tacomas (and 4Runners and Landcriusers, I think) with the hybrid iForce Max power train have a 120V 2400W outlet. It will run briefly from the traction battery before starting the engine to recharge.
