53 cents per mile.
A brand new 2010 Toyota Tacoma V6 4 door double cab with four wheel drive will run you 63 cents per mile, and that is including the insurance, maintenance, and repairs. Back that out as you did and you are down to 44 cents per mile on the Tacoma. Source here. They were a bit high on the insurance costs in my view.
So we have a choice of a roomier truck with the added benefit of getting to 4x4 trailheads, at 9 cents per mile cheaper than the electric car. On top of that it has the benefit of a smaller capital investment.
Seems like the Tacoma is your better option. Shall we get a group together?
