Jeff,
I had precisely the same arrangement with no problems for 20+ years. When something did slip, I reset it, and tightened the bolts another 5 inch-lbs. Eventually nothing slipped.
It did come down one night, but due to a gust of hurricane force winds and an unseen rusted bracket which brought down the entire tower in about 5 seconds.
73s,
Alan WA4SCA
