Hi,
I removed my AUH today and noticed some unexpected wear on both the Curt gooseneck ball and the Andersen coupler tube. Of the two, the coupler tube is a far bigger concern.

The coupler bolts have worn about 2/3 of the way through the coupler tube. The indentations from the coupler bolts into the coupler tube are about 0.15" deep and the material for the tube is only 0.22" thick. I am wondering if other users of the AUH have seen this type of wear as well.

The lesser concern, and maybe more of a curiosity, is the wear on the Curt gooseneck ball. Below is a picture of the ball.

The only point that the hitch connects to the ball is through the pin in the coupler tube, which is only at one point on the ball. I would have expected there to just be wear at a few spots on the ball, not all across the surface as shown in the picture. It looks like the coupler pin is wearing the entire surface, which could only happen if the coupler pin is moving up and down and across the ball. I can't see how this can happen, but it definitely is wearing somehow. I am curious if this same wear is seen by other AUH users as well.

I have contacted Andersen about the coupler tube to get their feedback and ordered a new coupler tube as well. I planned to go on my first trip of 2021 on Sunday but those plans may be on hold until I get the new coupler. Any feedback from AUH users on their experiences will be greatly appreciated!
