My 2013 F250 has sway control built in, although I'm not sure whether it only uses the trailer brakes to control sway or whether it also uses the truck's brakes. Not sure if it's ever been activated though. There isn't a light on the dash that comes on when sway control is activated. I imagine the Chevy and Dodge also have sway control in their HD trucks but I've never checked. Ford did a video that shows their sway control in action on a severely rear loaded trailer. Interesting to watch - find it on youtube.
