I've been buying and parting out Ford diesels for the last 7 years or so as a hobby more or less. The parts are easy to get rid of as there is a huge market in my area, everyone drives a Super Duty. I enjoy it because I get to take things apart (and not put them back together), plus I get to hoard parts for my personal projects.
One of the reasons I like Super Duties is the parts swapping potential. Nearly 20 years of the same basic body style and interchangeable parts. They're like Legos for big kids.
