One of my scouts called me from an auction last night with a 91 D250 CTD 5 speed. 338K on the clock for $2200. I told him to go drive it and if it was ok to buy it and bring it to me. This afternoon he rolls up in this truck. It looked like a forward observation vehicle from Desert Storm. But... ... ... ... it still runs great with no blow by and the A/C is still blowing cold. These are some tough trucks.
