Picked up a 93 Cummins Dodge a few weeks ago for a crew work truck. 71K original miles. Those old engines are great, sounds like a Swiss watch, the old trucks themselves not so much! I don't think it will ever be worth much, but I do know it will serve me very well, for a very long time, for it's intended purpose. The best part is it's paid for so all the driving is pure gravy.
I drive a 99 Cummins 4x4 every day as a work truck, and will drive it until it becomes impractical to maintain. At 175K right now, and the truck is almost perfect.
Must be getting old as the appeal of new trucks is past.
I did buy a Toyota Tacoma last year, but I'm not in love with it. 2009 with about 70K miles, might be for sale soon.
