I suppose if you were gonna swap a diesel into one of these trucks the cummins B series 12v or 24v would be the way to go. Kinda heavy and not especially responsive engines(although the 24V isnt too bad) as compared to the other light truck diesels but the cummins is so much more reliable than any of the other light diesel engines its practically a no-brainer.

Like others have said, beware of the 12 bolt if you're gonna tow with it. We had a ram 3500 4x4 in our fleet with a dana 80 rear axle that they used to plow with. If you've ever seen a Dana 80 compared to a 12 bolt the 80 is huge in comparison. I rebuilt the rear diff in it 3 times before I installed a detroit locker. After I installed the locker it would just break the rear axles so I dont even want to think about what that motor could do to a 12 bolt.
