1985 Dodge Ram 250 Cummins Prototype - TruckTrend Magazine

At the staging area for the 2014 Ram Truck drives, a rare specimen was on display. It was a clean, nicely-restored Ram 250 long-bed, regular-cab truck. It was familiar enough as the bodystyle of the first Cummins-powered Ram. But closer inspection showed some differences from the production-model trucks that ultimately rumbled into showrooms and started the diesel performance revolution more than two decades ago. At first, we thought, "Oh cool an old Ram diesel. " But the Ram PR staff said, "It's not just any old Ram diesel, it's THE FIRST Ram diesel. " And by first, not just the first production model off the line, but the actual very first mule that was used as the validation test-bed for the Cummins B59 in a lighter-duty (i. e. non-commercial) application. Consequently, the truck received a full bumper-to-bumper restoration, including new paint, new interior upholstery, trim and carpeting. Source: www.trucktrend.com
