he planned for 30 days and it wound up taking 60. he didn't strategize to minmax it, though? there was a lot of up and down and he stopped mostly at places where there were fun public camping parks. also he went solar -> battery -> ac -> tesla with an alternator to a standard tesla house plug iirc? whoo.
i think there was an interview later where he said, "yeah never doing that again" or something to that effect.
