Most of the men with Rams/Dodges with 3/4 tons have the Cummings diesels and they seem to love them. They still don't use the exhast fluid yet, 2013 I am told, but they are made in Mexico.
You might be interested to know that the chassis is what limits the 2500, not the engine. Since the Hemi is 900lbs lighter option than the Cummins, it has 140lbs more payload capacity and the 4.10's on the hemi match the max trailer cap of the 3.73 geared Cummins (the 4.10 Cummins eeks out another 1100 max trailer, but with less payload that won't matter much for a 5'er since you are at the Hemi's 2460 payload with a max tow capacity 13.5k FW at even 18% pin).
Actual towing experience is still better with the double-the-torque oil burner, and fuel mileage will probably be better, but the Hemi 2500 ultimately has the advantage for the payload for a 5'er.
