Well in the case I presented the generator would stay with your rv/ or whatever you're towing this thing around with, as I explained, a lot of people use these types of vehicles in more remote areas. You don't really need the engine for going out during the day, only for recharging at the end of the day. This means a much simpler design and less weight to drag around. A generator is much easier to service and maintain that an engine attached to the vehicle.

Of course I'm talking about a small niche of customers in an already small niche of people that buy 4x4s.

Is that always true though? I could see doing that for longer trips (rare) and leaving it at home for the remainder of the 90% of trips.

I'd bring it while towing something heavy as a safety net. Towing will affect the range in ways which aren't easy to calculate with hilly terrain even if you know the weight of the trailer + cargo.

Not necessarily - you might only charge using the generator every 20th cycle; the other 19 you might leave it at home (or in your other vehicle, or whatever).

That's the idea of a hybrid, no? For a lot of the places I'd want to go camping in a truck like this, I'd be likely to want a generator anyway, so I might as well trickle-charge the vehicle back up whenever the power is on.

That was my thought. Looks to be plenty of room in that front trunk for a generator to make this a not-so-poor-man's hybrid.
