Its really entertaining reading these treads with the trolls blocked. You see reasonable posters trying to stay on topic with relevant cogent information. And.... that's it. Strange!

This isn't a unibody, though.Unibody is the best option for an EV.
So what's everyone's thoughts on the stainless unibody. As opposed to body-on-frame

Could aluminum work for that purpose? Not as durable but, would the lighter material (As opposed to stainless steel) help extend the range and add towing abilities?But if the drivetrain is good for 300k+ miles as is anticipated, it makes sense to make the body as corrosion resistant as reasonable.
I doubt it. Since the body is structural the aluminum would have to be far thicker to compensate for being weaker. It's certainly possible. But I wouldn't bet much weight savings.Could aluminum work for that purpose?

workers will want to see out of their cabin and that won't be possible with the A-pillars raked at such an angle.
Aluminum has some other issues with fatigue cracking. Corrosion resistance is good depending on the alloy. Since welding returns the HAZ on aluminum to the zero temper condition, most aluminum bodies are bonded and riveted together. This adds cost, and there is crevices for corrosion.
Aluminum itself is not very corrosion resistant. The oxide layer on its surface is. Certain chemicals disrupt this layer, so you need to use marine grade aluminum, which has lower strength, or you need good coatings. Aluminum is a bit harder to repair.
Aluminum is also a lot hard to form into complex shapes (everything except this truck, lol!). One option is superforming with high pressure gas, but thats expensive. For non structural panels aluminum is a good choice to cut weight.
Goodwin said Tesla had a history of prioritising occupant protection ahead of other areas of ANCAP testing, including pedestrians and cyclists.
He pointed to the most recent Tesla Model 3 ANCAP rating. While it scored five stars, the vulnerable road user score was the lowest of the four categories evaluated, at just 74 per cent.
“We’ve got a concern that Tesla is very interested in the occupants of the vehicle, but it can’t ignore the other road users as well,” said Goodwin. “ANCAP’s protocols are well known and what we would expect is that a vehicle should be able to protect the occupants of the vehicle as well as those other road users … including pedestrians and cyclists.”
“Thinking about other road users there, it’s got a fairly harsh front and not a whole lot of areas that would provide some give if there was a strike with a pedestrian,” said Goodwin of the Cybertruck.
Goodwin also questioned the thick steel “exoskeleton”, which Elon Musk says makes it tough and resistant to dents, something demonstrated by attacking the concept car with a sledge hammer, something that left no marks.
“We would expect that a vehicle should be able to absorb some (crash) energy because if it doesn’t absorb some energy … it will be the people inside the vehicle who bear the brunt.”

I think he let the engineers run roughshod over the artsy fartsy designers to get it that ugly.
But If it works and they can build it with the tooling they have then I can learn to like it.
