One thing that would help others to try and help you would be to know the year and model of the camper.
There is loads of information on the net concerning the lifting system and from past experience they are not all that hard to repair Just time consuming and working in cramped spaces. I had a similar with my 2000 Heritage and the problem was a broken eye bolt where all 4 cables attach to the main lifting cable of the winch.
See attached pics 1st is what was broken 2nd was after repairs were made Not saying this is your problem but thought this might help.
