Pardon my language, but this idea as stated is lunacy. Carrying a Genset to try to drive the truck is crazy. Have you looked at the size of a 25 kW generator? It usually comes witha a trailer or truck to move it. On the other hand, carrying a 5 kW genset to "charge" the battery while parked could make sense as a way to double your mileage by charging for the trip home. But then you would be running it for hours.
For reference, the capacity of the generator in a Prius is 50 kW (peak power). Of course this is instantaneous. To cruise down the road might take 20 kW. Make it 10 kW and then you can drive with a 50/50 duty cycle and you are starting to look like a hybrid. Good for in-town driving where there are equal stops for every go. But to cruise down the highway at constant speed for hours at a time is a HUGE generator. So better to invest in lithium batteries to cut the driving load (weight).
