Ford was bailed out by dodge awhile ago...needless to say they bought shares of ram and used the cummins motors in their heavy duty trucks such as their 450's and up

The 5.9L is better! The 6.7L is ok. It would be a lot better if Chrysler designed a transmission to be able to handle it. The Cummins QSK45 sounds pretty gnarly right Patrick Hoisington?
