You could probably get a gas powered generator and use it all your life for that usage while still polluting less than if you bought a whole ass 3 tonne car
Personally, I’d prefer not to have a generator nearby. Storing fuel, noise, exhaust—all things I’d prefer to avoid. And as I said, this is not the vehicle that will solve the problem for me, since nobody yet makes an EV that would work for my usage, but when they do make he EV I want, this will be the primary feature I want. I was planning to setup solar at the location to charge a small battery for an hour or so of power a day if I spend a week at the location, I can plug the truck into the solar to trickle charge during the day.
A 1 ton gas car is going to pollute far far more than a 3 ton EV charged from the average American electricity mix, and that mix is not particularly clean, even.
