In 2000 I was passing through Kalamath Falls Or and I saw two "pipeline pickups" for sale at a farm supply place called Sunny D Manufacturing. They had a CTD, Dana axles, heavy sheetmetal body, it looked like pete or kenworth headlight groups, and they were four door. They sortof looked like a small semi in body style but they had the size and ground clearance of a pickup. I had heard that they were made in AZ for the AK pipline.
