There's no diesel in the bush either. So how do you refuel a diesel vehicle? You haul it in. How do you think a diesel generator would get into the bush? Haul it in with the diesel. An off-road tanker can carry 40 tonnes of diesel into a camp. A generator doesn't add much to that.
Have you got much experience running an off-road operation at distance?
A tanker, even empty, cannot get into the bush. Even an unprepared 4WD is often unwise to take into the bush. A few jerry cans of gas in the bed are no bother at all.
I was just thinking about the water trucks in Nepal. They go anywhere, it's impressive.
You probably know things that the person you are replying to doesn't and arguing is futile.
Nonetheless, electric isn't so great if you have to pack generators to make it work. It defeats the purpose, right?
My comment up there was from the perspective of a long distance motorcycle traveler. When I look around, I see cars that are already packed: children on parents' knees, one child in the back, and luggage on top. A generator and fuel wouldn't be trivial to add to this.
Above all, it means that fueling up becomes something you can only do where you stop. It's no longer a five minute break, but a constant logistical issue.
I'm not saying that it's impossible, but it's a tough sell. Have you seen The Long Way Up? They attempt a Pan-American trip with electric bikes, and boy what a headache.
