Electric is NEVER going to be your only option. You think that the oil lobby is gonna let this happen... so naive!
Regardless, electric is better in every aspect, and particularly off road when lots of torque is needed. Just have to wait for fast chargers to be as widespread as gas stations in order for them to be usable on long road trips away from home. Plus, unlike conventional cars, they run on REAL batteries and will always start, unlike those Pb POS that die with no warning after too many times opening/closing the doors while car-camping (happened to me twice last week, on my Outback, then once a stranger rescues you, you drive to town to get your battery tested and they tell you it's fine, lmao).
But I wouldn't count on conventional carmakers to develop the GOOD electric vehicles. They will always drag their feet to develop POS that are intentionally inferior to their gas powered line of products (for instance Subaru with the Solterra, which has less clearance than any of the Outback, Crosstrek, or Forester and is also not available in the Wilderness line...), so that they do not sell well and that they can throw the towel later and whine to obtain govt subsidies when they are about to fold.
Fast forward 5-10 years, I think the best vehicles for CO mountain roads will be the Rivian, whereas the best vehicle for highway use already is the Tesla.
For the time being, the best compromise between fuel economy, cargo space, clearance and off road capability is imo the Outback. But I am not religiously pro-Subaru (see my above rants), I just own my 3rd by pragmatism.
