I love the idea of electrification on any cool or classic car but think you would have to choose the vehicle wisely to make it worthwhile. The food would be terrible as there is no good place to store the batteries. Pickup trucks with a false bed in the back make sense. I saw a be van converted that was amazing too. Now, when batteries become smaller, lighter and more powerful then it will open a lot more possibilities.
Have you set up a solar charging station at your place yet? To me having the electric transportation along with free charging that’s not grid dependent is one of my biggest prepping goals.
