Can you guys give me the LOW DOWN between the GM/Chevy PU & Dodge

Yes, read up on some of the 12 valve cummins forums, I know of MANY of these trucks that are still reliably going strong. The Cummins, being a much heavier engine, got specialty suspension and frame work that the other dodges of that era did not have. The word I use to describe a properly maintained 1'st gen cummins Dodge is "ANVIL"!
