At the same time if you only drive your truck 200 miles a week you should be able to run a gas truck for many years unless you have the rust problem we have here in New England. I don't know the expected lifetime of the new electric trucks, but if they last for 10 years the truck alone costs almost $96 per week before any energy or maintenance. If you can keep a vehicle running for 20 years, which in your case is 200,000 miles then your per week cost is about $50.00 less. That increased life would pay for your gas bill at $3.00 per gallon and 200 miles per week at 15 mpg.
What you need is an electric truck that will last for 20 years, so you can get 200K or more miles out of it.
But realistically rust is your biggest enemy if you want a long useful life for a truck.
In truth, the whole reason I'm thinking of an EV and I went solar is from inflation risk. Basically, I made nice money on mine and my wife's investments and we're retiring early in our 50's (she's already retired, I will in maybe 5 years). But I have a real problem with the fact that my power bill and natural gas bill didn't go way down after my kids grew up and moved out like I thought it would. That woke me up to inflation risk being a lot higher than a simple 3% or so, at least for energy stuff.
I thought about fighting it with investing. Basically my average returns outdo even energy inflation (well except for this year natural gas practically doubling in a year). But I've built up plenty of wealth -- at least enough to retire comfortably in my 50's. So I got a HELOC to pay for most of the solar system as my way of trying to control future energy costs -- at least the portion of energy I make on my own. At the end of the day, that's really what solar and possibly an EV are to me. A hedge against Dims monkeying with my decades of retirement budget.
