Also under debate is what size bed the pickup will have. 6'4" is the "standard" length, 5'7" is common though for full size crew cabs.
Considering a motorcycle doesn't fit straight-in for either of those lengths and you'd have to go diagonal or leave the tailgate down, I'd be fine with the shorter bed portrayed in the first render. And TBH I think it'd be a home run if Tesla makes it.
American-made, massive torque, free/cheap to drive as much as you want, all the luxury features, you can do your Tahoe trips for snowboarding just fine, camping and dirt just fine, etc. These matter to a lot of pickup owners.
Wouldn't really work for overlanding or more serious offroading, but it's not meant to anyway and 99% of pickup truck owners don't bother with those either.
