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.
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.
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.
