I was looking at these trucks for their performance towing and good gas mileage and the generator capacity for camping.
One of the write ups pointed out that you would be running a $50,000+ vehicle and a large engine to match a far more efficient $1000 Honda generator.
If you get the Hybird it comes with a 2.4kw generator. It is standard. Costs you nothing if you are buying the truck anyway.
At 400 watts the truck doesn’t even start. It runs when it needs to charge the battery with its 35kwh electric motor/generator. The battery on the f150 is 1.5 kwh so it would hold a load of 400 watts for a couple hours with just a few minutes of total idle time if any depending on the state of charge of the hybrid battery.
On the TFL video with the 7.2 kwh generator charging a car the truck shut off with 2400 watts on the generator because it didn’t need to idle to keep charging
