03 cummins, 19MPG no matter what I do with it. Bone stock. 2 jeeps on a goose from C Springs to Moab 15MPG. Mojor Maint since new? Valve adjustment and radiator hose and a water pump. Since the cummins is based on a commercial engine, the water pump was a 20 minute job and looses very little anti freeze when you pull the pump. Its 3 bolts and a belt. Now that I have figured out to let Cummins do maint on it, its cheaper than dodge and they know what the **** theyre doing.
