I don't think truck people will ever buy an EV truck. Its just not in there evoked set. This coming from growing up around people that made there living every day out of the back of a pickup truck. None of the supposed benefits of an EV truck are of interest. Truck people don't mind gas stations - they probably will go there for other things anyway. They don't worry much about getting more mileage - they may complain but in reality its the cost of doing business. If they need to go 600 miles in a day, they can in a ICE truck version. Does it happen often - likely not - but understanding the need to get a job done no matter what is a compelling argument against EV pickups.
So that leaves everyone else that uses a truck, and it seemingly did not sell to them either.
Mercedes bought Chrysler to figure out American's like cup-holders. The EV expenditures seem mild by comparison.
