Strictly electric, I doubt it. Hybrid, sure, as GM already has one, and there was an all-electric Ford Ranger if I remember correctly.
It will all boil down to cost vs. benefit. If they can build a capable truck for a reasonable cost that has significant mileage gains by having electric propulsion (either 100% electric or hybrid), then it will happen.
I think hybrid is more realistic and therefore more likely though.
Personally, I want an internal combustion engine in my truck. And my ATV. And my streetbike. And my dirtbike. And my sportscar. Lawnmower, wife's car, weedwacker, etc. - electric is fine with me if it works, don't care - as long as it saves me money I can put towards other things. If it doesn't save me money, then I'm not interested.
Like when my electric company offered to give me electric supplied from renewable sources (wind mostly I think) for about $7 more a month....and I said no thanks. Why would I pay more for electricity that should cost me less, since wind (and sunlight) are free? ??? Sorry, but I'm not subsidizing their infrastructure costs so they can make more profit.
