I am not sure about the Rivan
I am not sure about the Rivan EV truck. The diesel-electric hybrid would be the ideal emissions-compliant truck, you could put a centralized electric motor in place of the transfer case, the transmission would be the generator and the truck would still be able to carry another 1,000 lbs of just battery. It would be a hotshotters dream never to have to worry about the transmission, never have to idle, always ready to go and always getting the peak mpg.
