This truck seems to have most of the desirable Kei truck qualities (besides price) but it’s an EV with modern features.
I think you've missed a major component of Kei Truck popularity. You can literally get 10x Kei Trucks for that cost.
Also most kei trucks the side of the truck bed folds down giving you more of a flat bed which for some things is super super handy.
Ditch the crew cab and lower the height of the bed and you’re starting to enter the same territory.
