I just took a vacation this weekend, 2 hour away from me, (granted on Wisconsin roads and hills) just cracked 18.0 mpg on the display doing 68mph the whole time. Haven't filled up yet to hand check. I got a '13 1500 SLT QC with 3.55 gears.
Just went to lunch, truck display said 18.4mpg, filled up and hand calculated, came out to 18.48mpg.
