I'm really intrigued by this truck, but I don't consider myself an early adopter. I'll more than likely buy one of these as my next truck, but given I just bought a 2016 f150 king ranch last week (5 years old seems to be a sweet spot for mileage/depreciation) itll probably be another 4-5 years before I move in the EV vehicle direction.
I'm assuming that development on these will move forward extremely quickly. We forget that the internal combustion engine has a 100 year head start, but I think we have all of the building blocks in place to make this work.
One of the things that the nay-sayers never take into consideration when charging, is that the bulk of the charge happens really quickly. I wouldn't be surprised if within 5-10 years, they get the charge rate to 80% down to 5 minutes, which would get you at least 100+ more miles.
Add in an auxiliary module (as ford already patented), and range could be a non-issue.
