Found it abandoned on some property we inherited. Only seat is the driver's seat. My father, who I never knew, took it all over the place and was probably living in it for a while before leaving the country, though there is a small camper on the property too.
Dude has thousands and thousands of slides and negatives from all over the world (rake keeps getting tangled up in the spools) but it's all ruined and we're just shoveling it out with everything else. My mother tells me he had been to every country in the world except for two or three at one point.
Edit:
Looks like he was using this electrical box as a safety deposit box. All the papers are still like this.
