lots of misconceptions here.
The DC and the EQUALIZER are both friction based systems. The cams of the DC do not really add all that much to the friction. What happens is that there is more sway resistance when the TT is moving away from center and less when moving towards center..... BUT, it is important to realize that sway is a back and forth movement of the TT in BOTH directions.
The EQUALIZER has the same amount of sway resistance in BOTH directions. In reality it is pretty much a wash performance wise.
THe DC can be harder to install, but that was not a deal breaker for me. It seems that often proper setup of the DC results in poor ground clearance. That is an important factor for me.
Both systems rely on TW for the sway resistance.. The more TW, the more sway resistance they can achieve.
