New tow vehicle...6.4 hemi or Diesel?

Here is my recommendations
Diesel only
5.9 will get the best mileage hands down
6.7 makes a lot more power.
If you go the 5.9 route. DO NOT BUY A 2003 1/2 TO 2007!!!!!!!!!!
And here is my statement! I REPLACED MORE ENGINES IN THAT YEAR TIME FRAME THEN I DID ALL THE DIESELS BEFORE AND AFTER THAT TIME COMBINED.
Not saying you can't get 250,000 out of them years, but you better not chip it, And you had better have bought it new, and your maintenance must be superior.:soapbox: Rant OFF
With all that said i would still buy a 2004-07 Dodge before any year Ford of Chiv Diesel.(But i may be a little prejudiced:p)
