I'm changing mine from a power to a manual, probably next month. And I've taken great care of the unit. Cleaned every year, packed in fresh grease every year and added when necessary. But it had troubles from the first camping trip and has started to make some very disturbing noises when being raised.
So, before it happens, I plan on pulling it off, and installing a manual winch.
