Actually, this "could be", but not from the factory. A number of years ago some local loggers swapped all KINDS of diesels into their "woods rigs" typically 3/4T - 1T Fords and Dodge pu's. There was everything from small Detroits, 4 banger turboed Cats, to at least one Cummins V6.
AND I don't know if it's in production yet, but Cummins was envolved with developing a V6 and V8 diesel for Dodge pu's
