service recommendation, cable slide mechanism

thank you, doug, that manual will be incredibly helpful, and ill just have to, when I make my calls, ill be more informed when I call these places to replace my cable. The last time I had it done, at wildwood lazydays, I think I finally found a teck that had a clue. It took them 2 days longer than anybody else had taken, but was going on having it done right. The cable hasn't snapped, but im simply gun shy from having it snap (and of course at the worst times) so wanted to locate a repair shop before I took the slide in.

Thanks
