It's very driving dependent. I've gotten anywhere from 6.5 to 18.
In the spring/summer/fall I've seen 18 on the highway when light footed and forced to drive ~65. We normally get 10-11 but that's real city driving (stop signs or traffic lights every 300 yards). Towing our trailer at ~65 I get about 10 (actually managed a bit higher than that this weekend even with two kayaks strapped to the roof).
In winter we lose ~10% mpg due to the reformulated gas used here. I'm happy to get 9mpg in the city in the winter; often it's worse if I let the truck idle to warm up, or if my wife does a lot of 1.5-2 mile round trips to shuttle the kids to/from school and the truck doesn't fully warm up.
