I have an early Cybertruck reservation as well. But the more I think about it, the less I want one.
I think we're about 10 years too soon on electrics. Gas is still everywhere. But as you get out of the cities, charging stations become harder to find. You end up having to pick your route based on going from one charger to the next - it limits your freedom of travel. Which is what an adventure truck is all about. I pretty regularly drive across the continental US in my truck. I can pick where I go, how I get there, and when (for the most part, petrol tanks aren't bottomless) I stop. Can't do that in an electric.
Kudos to Rivian, it looks like an amazing vehicle. But I don't want to be tethered to charging stations. The did a great job beating Tesla to market, but I do hear the rumor that they've delivered only something like 25 trucks to actual consumers. Oh, and just about every video of the Rivian offroad event they hosted for media featured a flat 20" tire - the smallest diameter tire available, and part of the "off road" package.
Hard pass.
