Sound Guy, these items may be common sense to those that have been around trailers and automobiles for most of their life, but look into all the owners who can't even maintain their own personal automobiles, let alone actually bring them into a dealership to be properly serviced (and hence rely on the expertise of a dealership to recommend the right things for them). Some people are like this. just read
This thread on reddit to see the stuff mechanics have to put up with on a day to day basis.
The OP was a cut above and took matters into their own hands to resolve the mystery, and the hitch vendor also stepped up to provide support. Apparently this has been a good teaching moment for the OP and this thread will continue to exist to be a teaching moment for those that choose to read this stuff (Note: Those that choose to read this stuff). Most people wouldn't take the extra effort to make things right or do thorough research in the first place, they would just acquiesce that "Well I guess this is how it's supposed to be cuz the experts said so". Many people fall into that trap. I'm not making excuses, but we do need to acknowledge that most people won't put in the effort to truly understand something if it works well enough for them. Hell, the Glen Jackson bridge was plugged up a few weeks back because someone's travel trailer became detached and blocked 3 out of 4 lanes of southbound traffic. Guess that owner should had known better, but the event still happened... People....
