That's an insane amount of work. An amazing adventure and a saint of a wife!

Did he ever finish the headlights and other small items?

and now what does he do with all the duplicate/spare parts?

I've done a couple extremely high stress road trips, so I fully empathize with him passing out every time he had to pull over. What a fun read; I love these ultra-long-form articles.
