The Tesla truck could be a real game changer, if (big if) it is cheaper to operate alot of fleets will flock to it. Not all trucks run cross country, lots run out and back to the same terminal every day, beverage trucks! The diesels are so complex, think of this, no radiator, engine, exhaust after treatment, transmission, driveline or differentials. That is a lot of weight that can be replaced by batteries. Power to the electric vehicle, it leaves the gas for us!
