These vehicles come with a F 350 with a Cummings Diesel engine to pull a generator.
You can can just plug it in as you drive and keep it charged.
Of course the two trucks have to stay within a few feet of each other.
Too bad you can’t get a Cummins diesel in a Ford truck.
Someone I know thinks the ideal pickup is a Ford chassis, Cummins engine (Dodge), and an Allison transmission (GM).
