If someone at the factory sees this thread you need to add a metal frame behind the flange for your rivet to grab on to. Riveting to the fiberglass does not cut it!
From what I was told by my dealer ( truth? , I don't know) is that there is suppose to be a metal wall stud right at the opening of the slide box. The mounting screws are suppose to thread into this and sandwich the fiberglass between the tower bracket and the stud. If the screws are pulling out, they missed the stud on the assembly line. Like I said is this true? or just a line from the dealer. Maybe Josh can answer this one.
