Your van is probably better than mine, but when I was vanlifing with my wife, I really regretted spending so many long hours on the road. If I did it over again, I'd try to limit driving to a max of two hours per day and five hours per week. We spent far too much money on repairs and not nearly enough time writing code or exploring the places I drove through. Or past.

Are you reviewing code by voice, like a blind programmer? Have you tried Emacspeak? I know that's not normally hands-free.
