Equalizer vs Dual Cam
I am currently pulling a roughly 9,000 lb 34' camper with a Reese Round bar WDH and friction sway control. My bars are rated at 1,000 lbs, I am sure tongue weight is substantially more but they seem ...

Actually, DC is very proactive. Saying that DC is reactive only is to not fully understand the design. At least the old style like I have is. It actively prevents sway that is induced by the spring arm swinging laterally under the trailer frame. While the WD arm is in the cam saddle it is held firm. There is no way the WD bar can move laterally from left to right like a standard WD hitch spring bar. This is a proactive approach to sway control.
With a Standard WD hitch you can push the spring bar sideways while it is hitched up. You CAN'T do that with a DC equipped hitch. It is impossible for the spring arm to move laterally (unless something breaks).
When the trailer tries to sway and forces the WD bar out of the cam saddle the tension increases and tries to return the spring bar back to the saddle, thereby self centering the trailer.
The new Blue-Ox Sway Pro hitch advertises this as part of their sway control, they reduce the amount of free chain links, reducing the opportunity for sway to be induced by lateral movement by the spring bar.
As to where the DC and friction come in to play.. Friction results when something rubs something else. In the case of the DC a Metal spring bar is used and a Metal cam is used. When these two pieces join together they create friction.
DC is a simple design with a lot of things going on at once. Friction is part of it. The spring bar being prevented from moving laterally is part of it, the cams and the spring bar is part of it.
Geeze, I have almost talked myself to reinstalling the DC sway control on my trailer. LOL
Thanks!
