Here's a humorous sidenote…
Recently, in one of the regular email solicitations I get from RV accessories outlets, there was a special on a propane tray lock to replace the usual giant wingnut between the tanks. It was an unwieldy bright red gizmo with lots of impressive protruding flanges and a keyhole, and cost over $80.
I asked them whether the kit included a piece to lock the nut at the bottom of the rod, and they replied, "the threaded rod cannot be removed without specific tools which prevent an opportunity theft."
Whoop-de-do, a pair of pliers. I wonder if NASA would let just anybody borrow theirs.
