I have the Dodge with the Cummins. It is hands down, the best truck I've ever bought. 102,500 miles on the odometer now, and the truck has had only one thing break - the A/C compressor.
It's the first vehicle that I've ever bought, that I've kept beyond 100k. I intend to keep it at least another 400k.


A bit of history on the Chev. The 6.5L engine is an indirect injection design built by detroit diesel (a GM company back then), for use in the pickups. Pumps are stanadyne units that seem to have recurring problems, despite numerous redesigns.

The 6BT Cummins engine is a medium duty truck engine that was simply plopped under the hood of a pickup truck after a bit of detuning. It will out last the truck with little more than routine maintenance. There is one caveat. The ISB designated engines (like the one I have) with electronic controls do not tolerate their rotary injection pumps being run dry. This causes premature failure. The work around is simple. When replacing the fuel filter, insure that the system is reprimed and full of fuel before restarting the truck. If it does stall, loosen the supply line at the pump, and reprime again, tightening the banjo bolt when fuel begins to leak around it.
