So I'm guessing your trip is: 120 miles to the trailhead, 60 miles of wheeling, and 120 miles back home; total 300 miles. Right? And then you doubled that to compensate for the fact that off-roading is less efficient. But that's not quite right. You only need to double the 60 off-road miles. So your equivalent range needed is 120 + 120 + 60*2 = 360. So if you believe Rivian's numbers you would get home with 40 miles to spare.
See above. But if don't believe that (and it is open to debate how much an EV off-roader would use in various kinds of terrain) you could still charge once during your lunch break without costing yourself much. If you do that whole 8+ hour trip without a break you're a tougher man than I.:yup:
We're not there yet but it's not as bad as you may think. Here's a map showing all the Tesla Superchargers (60% in 1/2 hr) in red and Tesla "destination chargers" (full charge in 5 or 6 hours) in black:

That's as of today; Tesla is building more as fast as they can get building permits. There are also a large and increasing number of non-Tesla high speed chargers:

In a pinch one can also charge at many campgrounds and RV parks. One can also get a 50% charge overnight almost anywhere there's electric power.
Is this as convenient as gasoline? No. Is it really much of a burden? No, again. The only real inconvenience is that it takes a bit of planning to find the chargers. But, of course, Tesla makes that easy by displaying them on the NAV screen in the car. Charging time is a bigger issue. (The power level of a gas pump is truly awesome.) But my experience has been that it is usually convenient to combine charging with another stop that I would have made anyway. Sometimes not. We're not there yet. But it's not as bad as you think.
