Regarding the labor costs, consider that you can go work in an Amazon warehouse and make ~$22 an hour for essentially unskilled labor.

Maybe working on an American Foxconn plant would be more desirable (I have my doubts) but I still couldn’t see the labor cost being less than $25/hr at a bare minimum

I think a generator for that purpose would likely make a lot more sense. I can’t see buying an electric truck just so you can use its battery to weld. Maybe that’s a nice to have at best.
