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...

However the snap up on 1,200# and above can still fail due to the top springing open.
I think we've established that number is no more that 1,000# at this point....

By bolting the snap up on that bending action that you so very well show in your sketch is not allowed to start.
Agreed. But, can you really through bolt the top hole. I think it almost lines up with the pinch bolt on the other side.
The most frustrating thing is that I spoke to Reese a few days before this all happened and they were supposed to send me rivnuts for the DC and snap-up mounts. I made it clear that I had lost trust in the self tapping screws. I wish I had just zipped one of the self tapping screws in the snap up mount while waiting.
Oh, and those rivnuts still haven't arrived....
Also, just to be clear, that drawing is not a bending action. The motion presented in that photo happens as soon as you snap up the bar. No excessive load, no turns, no bending. I think it's because the angle between the frame face and the top on the bracket is greater than 90 degrees.
The pinch bolt is parallel to the top of the bracket. So when you snug it down the top of the bracket is is flush to the top of the frame while the face of the bracket is not.
As soon as you snap up the bars, the bracket moves to other position where it's only touching at the pinch bolt, the top outside corner and the center of the tube. That's why I don't understand why this issue isn't more widespread.
I suspect the pinch bolt digs into the frame a little at that time and presents an even more concentrated point source ....

The bolts if drilled at the top of the hole in the snap up prevents the downward force from springing open the top of the bracket and also prevents the bracket from starting to pivot outward to apply a point load to the bottom heel of the snap up putting a lot of pressure on thin tube frames.
So my understanding of excessive load on the tube when installed as shipped and according to the instructions is correct?

It is not always "obvious" to everyone which way things should be.
Yes, hence my reference to the sticker.
