I can confirm this information. I test drove a 6.6 Gas CC LTZ. Drove a 15 mile loop consisting of two stop lights, a busy traffic circle and rolling/winding country roads (45-60mph). I turned around in a parking lot and aggressively got up to 60mph once back on pavement; was happy with perceived acceleration. When I pulled back onto the lot the dash read 15.5 mpg. I did the same loop in my '13 5.3L ext. cab and got 15.0mpg. 

 

Exactly my reasoning to get back into a HD truck from my 2013 1500 CC 5.3L which averaged 14 mpg with everyday driving over 93K miles that I owned it. I needed the 3/4 ton and figured that if it gets the same mpg as my '13 1500 I wouldn't complain a bit.

 

I have 450 miles on my 6.6L gasser and it has felt great. My first fill up at 265 miles (only because gas prices were jumping up) had the computer reading 15.0 mpg but I hand calculated 13.8 mpg. This truck with a 36 gallon tank has a pretty big range compared to what I was used to! At 200 miles on the tripmeter it was only down a 1/4 of a tank on the gauge LOL This was a mix of work commute, about 120 miles of highway between 70-79 mph and 2 lane roads.
