If you really want to make a successful utilitarian line of EV trucks you need a DC V2L standard capable of delivering 10 kW or more. Maybe something like USB-C PD with communication lines reduced in number and the power wires bumped up to 10 or 8 gauge wire. That would enable you to make BLDC-powered truck accessories that perform better and are cheaper than gas-powered alternatives.

For example, a BLDC powered wood chipper with a 5 kW motor could chip branches up to 5” or 6” and, due to the nearly flat torque curve, it wouldn’t stall out and need to be unclogged like a gas-powered version. Log-splitters, post-hole diggers, saw-mills, etc. that are powered by small gas engines would all be vastly inferior to their EV-powered BLDC counterparts - both in price and performance.
