Winnebago, Schwintek In-Wall Slide-Out system - Problems ??

The HWH hydraulic slide systems are pretty tried and true. I believe that is what Provost and Foretravel uses. Guess Winnebago and others decided to go cheap to keep the costs down. I saw the Schwintek system on a new Winnebago at a dealer two years ago and my basic country boy mechanical mind thought it looked flimsy. From what I have read on several forums, apparently it is.
