One of these days we will have big enough batteries to power a superduty a reasonable distance. I can't wait. I've loved my EVs, now I want that for my F250.
A bigger concern for me is the charging speed/infrastructure for what an F250/350 might want to do. For me, that's tow a 5th wheel or trailer a UTV for hundreds of miles. Need better infrastructure and much higher voltage packs to make that viable without spending hours at the chargers blocking parking lots.
