Here is some interesting reading, ya never know!
All I can tell you is that sway control defaults to on all the time. You have to turn it off every time you crank up. I actually felt the brakes release when I turned it off on the interstate. Mileage immediately went up.
I assume there are some kind of rate sensors in the rear of the truck that detect sway.
I know based on my experience that it was activated and I had no trailer connected. I would assume it is there for when you have a heavy load in the bed as well to help prevent rear sway.
As for the 02 Sensor, mine was fine. Not my problem w/ poor economy but could be on others.

I have a pretty big cap on it and some weight in the back with my tools and materials but I find this figure a little poo-like. My beloved Excursion (7.3 psd) gave me 16 mpg or so on the same run with the same tool and materials load on board.
I am going to look for the sway control on the menu and see if that makes any difference, never know.

I have about 230 miles on mine thus far, and in mixed driving (no real highway miles yet) I'm getting 18 mpg on the gauge on the dash. I'm thinking that 20-21 mpg on the highway isn't out of the question. Mine is a 4x2, 157" WB, 3.73 rear.
