Mine is a '06 3500, Cummins, 4 X 4, auto. Not towing, I get almost 19 mpg as long as I keep the speed around 70, any higher and the mpg drops to approx 17. With a 26' enclosed tag trailer loaded to the max (10,500 lbs), I get about 12-13 mpg, unless I try to run over 70, then it drops to about 10.5-11. There is no lack of grunt here though.

CUMMINS When they went to 24v the mpg dropped. My 12v doesn't hesitate to see 24mpg highway with a non lock up converter. My brother's 97 12v will get 28. Both trucks have fuel and turbo mods. Edit we both get around 20 towing kinda heavy and not pussy footing them, they belch smoke from a stop, spool up and GO

No. I have a 2013. 6.7L with 3.42's. Empty I get 22 area at 70-75, if I drive 55 I'll get 25. When pulling my 28ft enclosed with cabinets/insulation/car etc.., around 12k I averaged 13.5 from Mi to Pittsburgh. It'll do a bit better on flatter tows. The exhaust brake is phenomenal on the new trucks. Also, you use about 1 gal of DEF per 1000 miles at about $6 a gallon. Just an average though. Good luck. Also good first hand knowledge here too on 2013+ http://www.cumminsforum.com/forum/2013-general-discussion/

2009 6.7 litre with 6 speed auto 12 towing car trailer , will do 22 on the highway at 65. Had a 5.9 12 valve with a manual was a little better but not all that much. I have had 7 diesel pickups going all the way back to the first cummins in a pickup ( that was a gutless wonder) and none of them ever managed to get the mileage I heard claimed by others. On the flip side I did own a hemi ram and that was a pretty thirsty vehicle especially towing made the diesel seem like an economy car.

Previous owner (somewhere in its life) abused 96, 3500, 46re, ext.cab, long bed, 4x4, 280k, stock exhaust with catalytic converter(may be nothing left in there, don't know), & no motor mod's. Tires are taller than stock though.
My 1st pull was with a 28' inclosed with car. Not knowing what speed would give the best mpg, doing ~65-70 I got ~10 mpg. I was hoping for 12. I could feel the wind pushing hard on the flat nose of the trailer. Maybe I had a head wind too, don't remember.
This yr had a chance to check it empty, on a trip 20.7, that surprised me a little.
To town & around & back, don't know.

2005 Dually 18 highway empty and 11 towing a loaded gooseneck.
With some tricks it gets 23 highway and 14 towing.
I have been around some of the high mileage claiming people too. They seem to always have excuses when we are traveling together.
I am perfectly happy with a 7,600 lb truck that will run like stink getting 23 and pull like crazy and get 14.

Now do some fuel mods and get more mpg. 12v > 24v

I would never own a gas rig again for towing. Mine gets 15-17 around town and highway, 8.5-11 towing a 40' aluminum goose neck, chipped, exhaust, intake, stock tires and wheels. I tow around 75-80mpg but have tried to haul slower, doesn't much matter. It's a 2004.5, 3500 dually, and I laugh at people who quote 20+MPG, it's BS in my opinion. Every time I get in somebody's rig that gets that kinda mileage, it doesn't. Great power though and long living if you take care of them....

My Cummins was a 2002 with HO and 6 speed manual. I averaged 17 in mixed mostly city driving. Pulling an 8,000# trailer on the highway it would do 13. I had the gauges (EGT and boost) and 4" stainless exhaust. PO had installed different injectors, a South Bend clutch and I had a timing kit that I never felt the need to install. If you can afford the maintenance, go for it, every man needs to own a locomotive once in his life I loved it. Would I own another? Only if I needed the power every day and would use it like they should be used

I am not sure if I believe some of these mileage claims but once you go Cummins you will not regret it. My 06 gets and average of 16.5 making a tick over 500hp at the rears and will still get about 12-13 towing 10k.
