Default Cobra top hinge plate bolt failure

Thanks Mike. I think the open trailer in the wind theory is very
good. I know that Andy and I have had to disassemble in the wind many
times and there is a tremendous lever arm working on the hinge plates
in that situation as you point out. That could be what has fatigued
the bolts in tension as well as caused the slight compression to the
fiberglass and the base of the handles. In my case the broken bolt
was discovered after a long drive back from Moriarity where my last
disassembly at Moriarity was in pretty strong wind and the trailer
was, in fact, not lined up to the wind as it should have been. So, it
fits with the patients history.
