I still think that's the way to completely electrify the F-Series and the commercial vehicles. The Lightning is, no doubt, a smash hit, but it's a niche product because of the lack of infrastructure to support it in the F-Series's biggest markets, and I don't see that changing anytime soon. If you're in one of the metro areas, a BEV might be able to git 'er done, but if you need to haul a load or tow a trailer all over hell's half acre, pure electrics won't tote the mail. A 6.8 PowerBoost might be just the ticket, though...
