I had a Dodge W250 with the first gen Cummins. I made a huge profit selling the truck on EBay, but that would have been great motor for the K30. It had a permanent case of paint mange. After many touch-ups, it started to look kind of stripey, so the previous owner finished out the job using a pictures from the internet, a viewgraph machine from work, and a few rolls of masking tape. And a few beers, I think. The brakes were a bit scary, though.
