I would stick with the DC. The EQ has the potential to do the same thing. Between the 2 the DC Is the better sway control hitch due to it wanting to pull the trailer back to center, whereas the EQ wants to hold the trailer at the position it stopped at.
Stick with the DC. In the 15 years I towed with mine I never dropped a bar, even in tight backing maneuvers!
This is a common misconeption that the manufacturer is happy to let happen. Makes for good marketing to those that do not think it thru.
First off the cams do not exert that much centering force to "pull" the TT back to straight. If it did, then you could not use it in slippery conditions as you would not be able to negotiate a turn....This is NOT a problem with the DC, so that means the cam force is minimal. Years ago we had a longtime resident engineer, Ron Gratz that did the calculations on the anti sway force of standard friction controls(single and dual), the DC, and the Equalizer. He stated that the primary anti sway force on all of them was....Friction. They were all pretty close.(standard dual) Search doesn't seem to work very well here going back that far, as I can no longer find old posts.
Second, one has to realize that sway is a back and forth motion, that increases with each cycle. A push away from center is not sway. The DC resists a motion away from center, and assists a motion towards center. IOW, there is a slight amount of resistance as the TT moves away from center, (beneficial) and a slight amount of assistance back to center,,,(Which is not beneficial), as that is part of a sway cycle. Fortunantly, the centering force is not that great, so it doesn't cause the sway motion to increase. The EQUALIZER provides equal resistance to sway in both directions of a sway cycle. Bottom line is thay both do a good job, they just do it differently
The difference to me when I used WD came down to other factors. The Equalizer has better ground clearance, so I went with it.
No issues with backing up. Had three different sizes over 25+ years, and they all performed well.
The DC works both ways.what goes up (the bars on the cams) must come down (the bars on the cams) yea it will still move, but the resistance to movement is much higher than the EQ which will want to stay where it stops. Simple physics.
