Thinking about trading my 2011 Hemi 2500 for a Cummings. I love my truck but was thinking about swapping it while it still worth something. I average about 12 around town and 8 pulling 9000lbs. My current ride has 4.10's and does the job around my part of the country just fine but just want to hear numbers from the real world guys on the Cummings. I am also considering the 6.4 Hemi. I figure the mileage should be on a par or a little worse the 5.7 but with more grunt. Comments, Thanks Jim T.
