Roger, I understand and cannot argue that reasoning. I'm just unhappy with the difficulty of adjusting the newer model cams, and the fact that with every different loading of the trailer or vehicle, to perform correctly, the cams really need to be readjusted.
If both cams are not exactly in the correct position...i.e. touching the bars in the front and the back of the bend when the TV is straight ahead, the anti sway does not perform correctly.
I've proven this to myself by using a feeler guage between the bars and the cams after making changes, and while doing adjustments. Also, the new type cams must be "persuaded" with at least a 2 pound hammer to move to the new position when doing the adjustments. The older "U" bolt attached cams would slide very easily to the new possition after loosening only one side of the "U" bolts.
I believe this is because the older cams where carried by a "U attachment" that distributed the load to both sides of the cam and therefore did not tend to twist the cam as the newer system does, because it's load is applied to only one side of the cam.
After using them for a while, it is my evaluation that the newer cam bolts get wedged in their slots when under the strain of the bar being loaded, and they MUST be loaded to get to the correct adjustment position.
All in all, it is my opinion that the newer design was of course intended to be an improvement, that in operation, has proven not as good as the original.
