I only recently got a personal electric car not because they only recently got good enough or only recently made sense, but rather because my last petrol car finally needed replacing. I suspect trucks are similar - they're not going to replace them right away when they have an existing one that is working fine and still has many years of use ahead of it. Keep using the existing ones until they need to replace them, then go EV. Otherwise you're losing that amortization of the capex
