Dodge/Ram diesel fuel mileage?

I have a 2005 Ram 2500 4x4 6spd man 4dr 6.5 ft. bed with 4:10 gears. I have been fantasizing about a new/newer TV. I have a few friends with similar newer trucks...the mileage they report is between 11 and 18 by the computer and general driving by different people.

I have not been using fuel treatment in the last year or so and have not reset my computer in a while. I reset it a few weeks ago and it was 20.8 with no recent 5er towing(whole other story). I got some treatment and reset it 3 tanks ago. I have only driven about 150 miles since and the rest is around town. Anyway...I wondering what your experience is with newer trucks. Here what it said yesterday.

No this isn't a fight or a brag. Just concerns and opinions.

5.9s get good mileage, but that is way to far fetched to believe. Something not giving you an accurate reading, not that those displays are accurate anyhow. Have you done paper and pencil figuring?

I usually run low to mid 20's in my 2003 when empty. Around 16-18 pulling pulling my loaded 20' flatbed.

Previous TV was a 2012 Ram 3500 CTD 4X4 Crew Cab Dually with Max Tow option which included 4.10 gears and 6 speed automatic. Around town average 13.5 mpg, driving empty on interstates sometimes 16-17 mpg, towing a 43' Toy Hauler (16,500 pounds) averaged 8-9 mpg. YMMV. New TV is a 2014 Ram 1500 Quad Cab 4X4 Ecodiesel with 3.92 gears and 8 speed automatic rated to tow 9200 pounds max. Around town average 22-23 mpg, driving empty on interstates 26-27 mpg, towing a 6,300 pound travel trailer average 13-14 mpg. YMMV

A week ago I just bought a 2012 Ram 3500 dually . 6.7 Cummings with 6 speed manual. Cruise set @ 64 mph getting 15 .4 mpg according to the display. Haven`t towed with it yet but I`m guessing it will be around 10-11 mpg range.

I was concerned about lower mileage on "newer" trucks. Thank you for your input. Assuming one day we will camp some more...and go more than 25 miles. I guess then I can actual mileage test. Maybe my ole truck is o.k. for a while.

Thank you again
