Oof yeah, if you work IN the van, standing room would be fantastic.
Right now I have work tables I flip out of my truck bed that all my stuff goes on. If I had to fabricate things on the fly more often, I'd definitely want the tall enclosed space. Slap an exhaust fan on there and good to go.
I imagine it's great for cold days and rainy days, too...
My work truck only clocks in at 1700. I might hit 2100 when I've got myself and all my tools loaded up.
I legitimately think my truck would break in half if it got hit by an EV.
