I need the 20” wheels because of bad roads, potholes, frostheaves, and general winter driving. I live in New England and specifically Maine, not Utah. I won’t be crawling slickrock. I don’t need the reinforced underbody to protect the truck from deep snow. There are few to no tire options for 21" wheels and 22" wheels are foolish in New England. It might seem trivial to the Rivian people, but I resent having to pay for reinforced underbody just to get the sensible 20” wheels.
