Personally I want a fully electric truck that looks like a regular truck.
If you pick say the light truck category epitomized by the Ford F150 series, probably the greater majority of what F150s are used for these days is mostly commuting or driving around with very little load, and then on occasion needing to carry or pull something.
What would probably work better than a fully electric truck, is if you had a truck with a fully electric drive train, that could do all the fancy regenerative braking stuff and independent power delivery to each wheel etc. But it had a smaller battery, (might as well make it plug in to make everyone fully happy), with something like a 40 mile battery range without cargo and then have the engine setup as a dedicated electric generation plant. Still also have a decent 20+ gallon fuel tank.
Manual override control over when to go all electric and when to kick on the engine.
Customizable and shareable power route maps so people can experiment with the best mix for a given route and share it.
That would let you use mostly electric power for all the small stuff as well as maximize energy recovery but add the following advantages:
Much less dead weight as you don't need this huge battery
Much lower cost, since you don't need a really expensive huge battery
No range issues, with a full tank & a full charge, possibly up to 500 to 700 miles and then easy fill ups on the road.
If you use it for commuting, you can plug it in each night without needing more than a dryer circuit and you'll almost use no gas
There would not be nearly as much strain on the power grid, which simply CANNOT support large amounts of electric vehicles without huge upgrades that are near impossible due to cost and the ever present "Not in my back yard".
Then at any given time if you want to go "more green" or something comes up with Gasoline, the engine part can be swapped out for an engine that burns LPG / Natural Gas / Veggie oil / Hydrogen or some new fancy battery pack.
