Not destroy itself, but seize into the receiver due to corrosion.
The aluminum clamps that held my old soft tonneau frame to the truck had to be cut off because of the corrosion between the steel bolts and aluminum clamps. Those bolts were seized in there solid, and they were up out of the weather and salt.
Granted there's no salt in Louisiana unless you live near the coast, and the process will take quite a bit longer than here in the Northeast, but I learned long ago after having one shank seize in the receiver, which required torching to remove, and having a couple of close calls, to remove the shank as soon as you've unhitched the trailer. Even if it rattles around now, it won't prevent the problem.
