Your doing better than I am, my 2013 with 6.2 gets 18 at 55, 15-16 at 70 mph. I have never actually verified that the trucks fuel eco. display is correct though.

I have a bb tuned 6.2 with the 3.42 gears and get 19 or so hwy at 55-60 near sea level and about 20-21 hwy in central oregon @ 60-65 (about 4k elevation). Interesting how higher elevation and hotter temps improve fuel economy...pretty sure it is just because the air is less dense in both cases.
Anyone else find it interesting the hp and tq #s for the 5.3 are significant...the 383 being a well known stroker engine size and the 355 being a bored out 350.

Thats the first thing i noticed.....
I made a couple trips to Texas in my truck. First time was goin to the South east texas meet and stayed at Silvermodo's house. averaged round trip of ~950 miles and a bottle of nitrous = 23mpg on 93 oct
Goin to DWF for a company training school i got 22mpg on the way over to there and 24mpg on the way home. Aired the tires up to 5psi below max and set the shocks on soft. Set the cruise on 70 and turned the radio up

Check out this link I found for 12 minute video review of the cc 4x4 with the 5.3. I wasn't too impressed with the 8.78 second 0 to 60!
