Folks are also forgetting the truck is likely MUCH cheaper to actually manufacture.
Stainless steel, mostly flat, design.
So- no paint shop. Which was a cause of a LOT of cost and woes in the Model 3 ramp.
Also no complex machines to shape body panels with a lot of curves like on the 3/Y either.
Some interesting stuff on the engineering in the truck here-
stainless steel in that grade and thickness is $$$. plus air suspension. plus Tesla Glass. plus gigantic battery
