The Chrysler and Cummins relationship started over 30 years ago, and there&#8217;s one important artifact that reminds us how far these two companies have come together: the first development truck. The truck was part of the initial fleet of six vehicles that were built to test the viability of a Cummins in-line 6-cylinder diesel engine in a Dodge Ram pickup. <br/><br/>Truck D001 is a 2-wheel-drive standard-cab long-bed 1985 Dodge Ram D350 Prospector. It started life with a V8 gas engine, but a 12-valve rotary-pumped in-line 6 was swapped in for the initial testing. Other than a simple mockup engine that was used to check space claim under the hood, this was the first Cummins 5.9 in a Ram truck. Once the program was approved, the actual test vehicles were assembled. <br/><br/>Troy Simonsen, a pioneer in the automotive diesel industry, recalled the first Cummins-powered Dodge Ram test mule: &#8220;I was on hand to test-drive the first prototype Dodge/Cummins diesel pickup, a 2-wheel drive, automatic three-speed. Cummins had set up a test run with comparable Chevy and Ford diesel pickups. It was a thrill to see the Dodge/Cummins outperform both of them with ease.&#8221; Cummins went into production in 1989 with the 5.9L for Chrysler, and the rest is history. Truck D001 is the truck that started it all. <br/><br/>Unlike today&#8217;s prototype vehicles, which are often scrapped, Truck D001 has continued to perform. For more than 20 years, the truck has been used as a parts runner among facilities and as a shop vehicle for the Cummins Technical Center (CTC). It&#8217;s spent most of its time on the highways and interstates in and around Columbus, Ind. The burgundy-and-white paint is faded, the interior is worn and the bed is a little beaten up, but the truck runs as well today as it did in 1985.</p>[/RAW]

It would be nice to get a list of the weak links that had to be addressed for the engine to be successful at this lowered power. So that putting that power back does not compromise the longevity of a first gen . Made it 350k mi before 4th split a planetary on factory tune, replaced with a 4th gen Allison 1000 70k back.
 
Nice story... love to hear stories of how products began.... particularly the Ram/Cummins lineage.

Thanks for posting. Please post more as info becomes available.

Christmas Cheers, Ron
 
For those that get the magazine there was an article on the other development trucks, and one of them was for sale. I hunted down the dealership from one of the pics in the mag and here it is.

Keep in mind my info is strictly from the article. The author certainly seems very credible but as always buyer beware. I know if I had the time and funds to dump I'd be seriously looking to verify. This is a piece of history.
