I had to drive about 450km (300mi) when I swapped out my '14 for my '17. Route is pretty flat, and I sat on the speed limit with cruise control on in both directions. My '14 had a leveling kit, and the new one doesn't. That being the only difference, mileage on the new truck was almost 12% better.

 

Went from 11.9 l/100km on the way down to 10.5 l/100km on the way back (19.77 to 22.4 mpg). If a leveling kit makes that much of a difference, can only imagine what a full lift with tires would do...

Just to give you another data point, I have a 2014 CC 6 1/2 ft bed, 33 x 12.50 load range E AT/mud hybrid Cooper STMaxx tires, 2" leveled front, topper, a few hundred lbs of stuff in it always. I get about 13 mpg in town, and 15 hwy. I don't drive like granny, but I don't drive with my foot constantly on the floor either. Some of each.
