I have my doubts.

It should be about the same exterior size as a Ford Maverick, with as much or more interior space as a Toyota RAV4, with a frunk as well as a bed

I actually like this plan if true. Yes the Maverick doesn’t have a full bed. But for my case, the stuff I would be hauling (if I had a truck) would be mostly garden supplies (i.e. mulch) and the occasional small to mid sized furniture. So a compact truck meets that need while not being too large and unwieldy. If they can improve the interior cabin space, that would be a bonus.
