I've never used sway control before but I found out the hard way, sway happens. Most sway controls help to minimize it after it gets started. It's best to not let it get started. That's why I just ordered Reese dual cam to go with my Reese WD setup.
Good luck with your friction based control I hope it works for you. I was fortunate enough to already have the Reese setup and the DC system was only $185 more. If not, I was going to try the route you are going.
Not trying to be argumentative, but I respectfully disagree.
Case in point, this trip:
with this rig:
with a Husky centerline active hitch and no sway.
By that I mean none. Nada. Zip. Zilch.
All 800-odd KMs of it.
Passed and passing tractor trailers, highways, side roads, construction, head winds, tail winds, side winds, up and down twisting mountain passes, avoidance maneuvers...... you name it, we saw it.
The truck never moved. The trailer never moved more than a small twitch to catch up to the truck on an avoidance. I watch the mirrors very closely when pulling. I want to know if the trailer is doing something before the rig tells me it is.
If you're set up right it will not "sway", which I define as an oscillation.
Definitely not enough so that you're knuckles go white or you actually have to look back to see what the trailer is doing.
Now, will a semi be able to "suck" you in closer?
Yup, but that's not "sway". The whole rig moves together as a result of the tunneling air effect between the two of you. Airspeed, pressure differential and all that jazz. Again, if your rig is set up properly that is.
Same thing happens when two large ships get close together going the same direction, the tend to pull/push towards each other. Found that out more than once on a RAS....
The other possibility is my rig is that one in a million jobbie that isn't effected the same by sway forces as those bound by the laws of physics, but I doubt it...
Just my .02
