Yesterday, we bought a pretty great 1971 Dodge Power Wagon truck.
It was owned by a police officer in Reno and then went to his daughter. He took great care of it and took copious notes for each upgrade and repair he did. We got a big binder full of scratched notes, warranties, and manuals. It had a cab over camper at one point, which we'd really like to do again, so we're happy that it has a few things done already that we won't have to worry about.
