When we bought our TV we had the dealer install the B&W Turnover Ball gooseneck hitch for us. We towed with it all last year, and this year when I went to remove the Companion 5th wheel hitch to do the annual inspection (and to help my daughter move), I found that the bolt that attaches the handle had fallen out. Guess that was lucky for us since when I got under the truck to reattach the handle I found this (see photos).
Today I took it back to the dealer & got them to put the washers in the proper place.
Out of the 16 attaching bolts used on the hitch, 10 were installed with the flat washer on the wrong side of the bolt.
We feel blessed that nothing bad happened while the bolts were installed improperly.
I have an annual hitch inspection on my list of preventative maintenance tasks but the importance of that inspection has certainly been emphasized by this experience.
