  I owned a 1996 3500 club cab diesel 4x4 for 9 years. I had the 3.54 axles and had no plans on towing, so I got pretty good mileage with the 12 valve Cummins and the 47RE automatic (best tank 24.3 mpg). But it did go down over time, and by 2005, I was barely reaching 20 highway.
  
  With the 4.10 axles and towing 8000, plus the age of the truck/engine, 11 mpg is not unexpected for your truck. Unless you're well over 300,000 miles, you're not due for a major overhaul, so there's probably not much you can do to significantly raise your mileage.

  Recently got back from a 700 mile trip from alabama to indiana. I was averaging 21.3 mpg at 55-56 mph. I was quit impressed needless to say. My city mileage is around 14 to 15, the trick is to keep your foot out of the pedal and keeping your rpms low is what I have found. I run around town at around 1100 to 1400 rpms and on the interstate i was running it at a constant 1900 rpms.

  I have a 2004 Dodge Ram 2500 with the 5.9l diesel. I bought it in 2008 with only 20,000 miles on it. I have 112,000 lmile on it now. I consistantly get 19.5 in town. On the highway I get between 22.5mpg and 26mpg depending on wind and hills. When I pull my 7000lb travel trailer I get 11.5 mpg and that is from Kerrville, Texas to Abilene, Texas which is nothing but up and down hills. It holds steady speeds pulling the traler up and down the hills unlike a ford diesel I tried which was constantly shifting.
