This has only been towed on reasonably smooth roads (excluding the odd field) and only very occasionally opened in strong winds . There is some slight compression to the glass shell at the outer mounting holes on each handle. When checking the bolt tightness I noticed that the nuts on the outside mounting bolts (inside
Andy: I certainly agree that once the bolts become loose they will be seeing shear load. I also agree that compressing the fiberglass shell over time is a certain way for them to get loose. That sounds like a pretty good theory. Of course, once they get loose, they'll be under increased tension cycling too. As JJ has said, the key thing may be to not let them get loose. I can recall
