I have wondered about them as well. If keystone has any models that only have cable slides, then that is where they would be used. My guess is that they work fine, but operate a lot slower than hydraulics. But still...would have to be better and faster in setup time than what I have seen with fifth wheels without levelup. Just so glad that our model had them. John
