I have the exact same truck except for the turbo. I average 11-13 mpg's empty. I haven't had my truck very long and haven't towed anything yet. The C6 tranny does alright, but needs another gear for driving around empty. Only having 3 speeds, my rpm's are at 2500+ just going around 60-65 mph. I try to keep it around 55, and I still get about 12. Hope this helps. Good luck.
