This is like Hummer all over again, it screams "LOOK AT ME!!!" and in an era where Tesla owners are either getting coal rolled, blocked at chargers, road-raged or vandalized I think the worst thing Elon could've done is gone on and on about how "bulletproof" it is. To me it just gives one more reason for ICE-holes to want to trash your vehicle.
The biggest flaw I see with this truck (besides it's looks) is Tesla's less than stellar build and reliability overall right now. I mean, a pickup truck serves a much bigger role in many people's jobs. If it breaks down, needs to go in for service or worse gets in an accident...truck owners can't simply get around via Uber when they use their truck for lumber, tools, building materials, etc. That is why Ford, GMC, etc. always advertise how tough they are built, and how reliable they are after X amount of miles, not to mention always have these huge chrome bumpers. Unless Tesla really turns it around by 2021 with their customer service, repair times, loaner options, etc. truck buyers are the types that won't hesitate to go back to ICE or even to a Rivian or F150 EV.
My gut tells me this will be nothing more than a vanity project, and when Elon sees the huge sales of the Rivian and F150 EV he'll get a more Tesla-like truck out to the public.
