I imagined that I would have one more ICE (or hybrid) vehicle before going full electric, but now I'm not so sure. I outside of Las Vegas, where gas is expensive by electricity (esp. in my town) is cheap and from hydro. We basically do three types of trips. Most my my exploring is done on day trips and the range of current electric trucks would be totally sufficient. I bet I rarely go over 200 miles. Push that a bit farther and you have weekend trips, a lot of which are really in the same range as day trips, but you can add Zion/Death Valley/Joshua Tree, all of which are within 200 miles (one way), so I'd need one (possibly quick) charge round trip. Obviously if I wanted to do substantial off road driving at the end point, I would need to be more careful with charging. The third type of vehicle supported adventure we do are very long, meandering multiweek road trips to see my parents in the East, but which we go via the Pacific NW/Idaho/MT/etc.. There are a lot of dirt roads and remote camping on these trips, but then you pass TR National Park in ND and it's mostly highway and campgrounds for the rest of the way. An electric vehicle probably wouldn't be the best for these trips still as we wouldn't be able to charge at the end of the day.
We have two vehicles though, and we could at first keep taking the long road trips in our current van, while doing the others in an electric truck. I think that electrification is starting to hit a tipping point, so I suspect that within a few years most places I would worry about now won't be problems for electric vehicles. I tend to keep my vehicles a long time, so I'd be basically buying now with the assumption that I'd be using it for 10+ years and the second half of that would have less inconveniences than the first.
My original plan was to buy a cheap, stopgap truck/SUV, use it for 3-5 years, then replace it with something electric, but with used prices so high I'm looking more at new vehicles, and then I start thinking if I want to be driving an ICE vehicle in 10-12 years. I do agree that there are some compelling hybrid options now. I was discussing it somewhere else on these forums, but I love the van form factors for travel, so the new hybrid Sienna looks pretty great. Add a Journeys lift and you have pretty much the ideal dirt road trip car. The new Maverick also looks really good to me as an efficient dirt road trip vehicle if they come out with a AWD hybrid version. So we will see!
