My '11 gets 10 MPG towing, maybe 14 or 15 around town. I drive it trailer-less so seldom that it's hard to determine my non-trailering MPG. Plus I have 4:11 gears, which were never offered from the factory with the stick. One road trip back from TN to PA, no trailer, it almost broke 16
And if you're gonna buy one, ya gotta spell it right. There's no "g" in Cummins. A lot of people do it, and it's a peeve of mine...
