This is what I'm super interested in too. If they can get battery development to the point of seeing 400-500 miles range, I'd buy one in a heartbeat. Loaded down and pulling a trailer all the time may be better suited for ICE applications, though. Charging station infrastructure just isn't quite there yet. That said, hot-shotters and such that haul long distance will likely go for the HD/Diesel options anyway, but the occasional short load haul for an electric truck could be practical. Pulling a camper/boat across the state, however...
It'll be interesting to see!
