I just had a major failure with my new hitch. Camping World installed it for me and used a ball that had threads hanging below the nut and interfered with the receiver sleeves of the arms. This caused contact between the sleeves and the threads when the truck and trailer made turns and resulted in broken and cracked sleeves.
Camping World has already replaced the hitch head, but the used the same ball.
Progress Mfg. has advised them they are putting the wrong balls on these hitches, and they are supposed to be ordering the right one to install on my hitch.
I am not bitching or ranting, just wanted to share so if anyone else is using the same hitch they can check to see if they have the right shank length and the threads do not extend past the nut. The photo is hard to see, but on the upper corner of the sleeve, you can see the gouge and just past that you can see the bottom of the threaded bolt extending too low.
