According to the Standard Equipment PDF from Milous, Trailer Sway Damping (BNT) is not listed anywhere on it as standard equipment....so my assumption is that it is something that "in" every Wrangler.....but may not be turned "on".
He has later updated a page for all of the Standards, which now shows Max Tow including Trailer Sway Damping....so who knows.

The whole thing is a cluster-fudge.

To be 100% sure, we need to find someone with max tow on a 2012, and check their build sheet for trailer sway.

On the window sticker, if it has "Max Tow" as an option, it does not display Trailer Sway as being included (the way Trailer Tow does).

Well I took my 2012 on the highway with 900 miles on it so I'm not sure if it's fully broken in. I must say, coming from sport cars and a h3 as a rental for a week, I was like a rabbit. I was trying to get into the left lane before a bmw 5 series got there from behind as we merged. I KIND OF floored it and I shot forward and left him behind and flew past the 18 wheeler I was behind. I think I have 3.21. I have an unlimited. I'm very impressed with performance.

I just picked up a 2012 Rubi Unlimited Auto with 4.10. My gf had a 2010 Sport Unlimited Auto with 3.73's that I'm compairing it to. The 12 is definately better all around and will hold top gear is pretty much anything I need it to, however it only "feels" slightly faster than our 10. I believe since the torque curve of the pentastar is so flat and quiet that you don't realize how fast you are going until you check the speedo.

IMO, get the highest gear you can. 4.10 for the Rubi and 3.73 if you are getting the sport. I think the 3.73 with 35's would be OK but the 4.10's 35's and the Pentastar will be a great match, auto or manual.

I have a '12 sport unlimited with Max tow. My build sheet does not list trailer sway damping.

I have one

I also ordered mine, and since it was right around when Jeep was starting to realize the towing ordering mess up, I just went with the max tow so I knew I would get 3.73.

2011 or older w/3.21's or more on the highway then expect to get passed by a prius. 2012 w/ 3.21's or more then a prius has no f'ng chance.
