myredracer is right from start to finish. The only reason I didn't buy and install the arms to my Reese HP with integrated cams in the trunnion spring bars is, I found a good price on a very barely used Equalizer 4 pt hitch. Otherwise the DC arms would have been the logical choice. And, like I do with the EQ, I would have put a little dab of marine grease or vaseline on the cams to keep it smooth and quiet.
For sway control to become activated on the TV, sway would have to be a problem causing it to activate. This would tell me the hitch isn't doing it's job of controlling or at least minimizing sway.
