don't remember if anything was said/written about sway control. I added a proportional brake controller from Hopkins IIRC, will have to verify that. incidentally finding where to plug the controller in was a witch with a capital B. it is buried under the kick panel on the left side behind a post? mesh, etc. two toyota mechanics and my mechanic could not find it until my mechanic really jammed his hand in there. we gave it one last attempt and if no go got the OK from the mfr. to return it and go with the remote controlled one, which I probably would have bought if I had known about it to begin with. that way any tow vehicle would work to tow my TT since the controller just plugged into the cigarette lighter socket.
will see if I can find out anything about sway control.
