Dual Cam Setup
I'm working on setting up a new Reese Dual Cam setup. I think I need a 1" extended ball, and wonder if I would benefit from a 2". Here's are some photos of where I'm at now: Side view, I think...

I have read other posts before that say "when in a turn all the WD lift is applied to one snap up" and I politely disagree! The bars have two almost equal bends, and when one is going forward, the other is moving back and has to be applying an almost equal force to its snap up. I would bet that if there were a method of measuring that force, the 2 would be very close.
When turning, for example testing for clearance, I have noticed that the inside bar rides back and becomes loose, hence my believing others when they say all the WD load transfers to the other bar.
If you look at the outside bar, it rides up on the cam. This must put more tension on the bar, but I can't say with certainty that it's taking all the load of both bars. I just assumed that the WD system is always taking up the same amt of tension and if one bar is loose and can be moved by hand that the other must be taking all the load. I have no proof that's the case and I guess it's possible that something else is happening.

Just another thought, if there weren't a space on the inside between the snap up and the frame, I believe that there would be almost no occurrences of bent snap ups and frames, with the possible exception of bar to head or bar to cam arm jamming. Maybe Cequent should make a different snap up for the common frame width on today's trailers, or some sort of filler to spread the load.
I think we are in agreement here. That would prevent the snap up from moving and if something out of the ordinary happens the pinch bolt wouldn't be able to dig in as far and the snap up wouldn't be able to lever over into the frame as much. I think adding a thick backer plate - or plates on both sides would produce the same result.

That is one reason I am leaning toward the new bar paint against a rough cam (and probably not the same wear area) causing the excessive forces when the snapping or banging occurred.
My stuff was all new too. The part in your thread that got my attention was the shaking of the tow vehicle. I've had some loud pops, but don't recall one ever fairly violently shaking the tow vehicle (Excursion).
