Maybe it was as simple as the "Mechanic" not tightening the set screws on the fender.(fender fell off.)
I already voiced my opinion that the set screws aren't big enough at one of the showings..
My motorcycle trailer has a similar application on the side boards. I use clevis pins with a retainer. Not a set screw. The side board is pinned through the stud.
