Look up one of the earliest FR posts. The bed is actually normal size, has built in tonneau cover and the towing is better than gas and diesel trucks. Downside is a fraction of the mileage.
Hardly anybody buys a Regular Cab, 8’ box pickup anymore.
The Tesla bed is apparently 6’ long.
Somewhere between the 5.5’ and 6.5’ [my current bed length -fits skis better].
The Tesla is a crew cab, but the 2nd row headroom looks short.
The Tesla truck is ~24 inches shorter than my current issue.
The range on my truck is often 700 miles [and I use it].
