Closest I'm aware of is the Slate EV pickup, but it is too small imo. Hoping their first model catches on well enough that they build one with a larger bed, heck, a bit larger all around really. I like the truck to be wide enough to fit 3 people on the bench seat in a pinch, so I guess I'm looking for a 'medium' sized truck - something I don't think exists today.
Failing that, I have an older F-150 that I just restored. Perhaps in another ~10 years there will be some nice donor electric vehicles that I could use to do a conversion myself.
