Huntingdog, I'm sorry but you're wrong on both counts.
Yes, it pushes the trailer back in line but there's nothing dangerous about it. I've even had it in the snow. Is the force "significant"? It is enough to do the job, nothing more. It is easily overcome when turning by the weights involved.
No, it does not use friction for control. It doesn't use brake material anywhere like other systems do. It uses pure spring pressure via the spring bars pocket climbing up off the cam. You could submerge the entire thing in oil and it would still work the same.
Best of luck to you.

Too bad, as there was some great info lost forever.
Ron was legendary in being able to dissect precisely how hitches work.. And yes the DC vs EQUALIZER was analyzed by him. I won't attempt to quote him, as it was beyond me at the time, and my memory would miss some points anyway.. But I do remember for a fact that he stated both hitches were primarily friction based.
He even calculated the amount of friction for steel on steel.... Just because there is no "friction" material like brake pads does not mean there is no friction.
As for you saying that you have towed safely in slippery conditions, I believe you. But that just destroys your theory of the DC forcing a 5-10K 20-30' TT back to center.
The cams simply cannot produce that much force. And if they could. since it would be present at all times, then it would create problems in slippery conditions.
It is a friction based system with the cams along for the ride. It does make for great marketing for those that don't do an in depth analysis,,,,, and it is a fine system in it's own right... But just doesn't work the way some think it does.
