Sold my 5.9/Banks-Cummins short bed crew cab because we tow a large horse trailer. Went for cabin chassis, 6.7 dually, crew cab, 4X4, Jake, 6-spd auto. Excellent flatbed by J and I in Madill, Ok. Dodge promoted the 6.7 as emission freindly but also "efficient." Now at 3 months and 7,000 miles I am getting 9 to 12 mpg towing, 12 to 14 mpg unfettered. Power is adequate, but less than the 430 HP and 830 ft/lbs I had in my old 2004 5.9 with Banks package. Lost rear signal and brake lights last week which dealer has experienced (corruption of a computer module) in these trucks several times. Reprograming solved it, but no permanent fix is available yet. The exhaust of this 6.7 is so clean you cannot get carbon dust on your finger from the tailpipe. It is as qiuet as represented by Dodge. The Jake break is supposed to be more effective than the one on my old 5.9. It is actually less effective in the new 6.7. The 6-spd Aisin trani is smooth and excellent. The sequential electric overdrive button on the shifter fails to provide an option to go from "tow" mode (5-spds) back to full overdrive (6-spds). You have to go down to "Overdrive Off" (4-spds) before you can select full overdrive again. Poor ergonomics. The huge, 9-ft flatbed is hugely more capable than a pickup bed. It has 12" sides and it is 8'4" wide. Lots of space for water tank and horse feed. Spare tire is on a headache rack extension over the cab. The std 52 gal gas tank gives us almost 600 miles of range which makes up for the poor efficiency. Hope Banks and others will come out with mods for efficiency and power soon.
