My 2013 LML: 20.5 on the highway, 15-17 around town, 11.5 towing my 5000 lbs travel trailer over in the mountains. (checking manually... the DIC is a little more optimistic than the actual mileage)

I just picked up my new (first ever) 2013 CC Duramax this week. Our camper is about 5,000 lbs empty and If I can get those kind of numbers...I'll be tickled to death.
Just did the first fill up (22 gal/320 miles) on my new LML. 14.5 combined city/highway (about half and half). Conservative estimate hwy...what, 18 maybe? No towing, just empty. Not too bad out of the box...I was expecting a lot less. My old 5.3l vortex got a combined 18.5.
