I live in rural PNW. Electric is at LEAST 20 years from being a feasible and reliable solution. ...and I say that as a civil engineer with some specialization in creating EV charge stations. 30-50 might be even be more plausible.
When I'm in the field, small things can turn into life-and-death situations pretty quickly out here when you're an hour and a half drive from cell reception, followed by another hour and a half drive to town with a small hospital/sheriff station, and you're up a dirt road where a tow-truck simply won't come. And the geology is notoriously unstable and slides/washouts/fallen-trees happen constantly.
My clients LIVE in those places, I only visit. They drive big diesel rigs (They often NEED to transport big heavy stuff, and you can store diesel for long time periods in a tank onsite), and a lot of them also have transfer tanks in the back of their truck for extra range. (Because it's needed!) They also almost all carry food/water/shelter/A chainsaw/tools/a gun/etc in their vehicle for a reason. Self-rescue is all you got a lot of the time.
