I had a 2013 38TKSB3 that also had the Lippert Schwintec on the bedroom slide. The complete system was replaced 3 times in the five years I owned it.
First time was by Sunshine RV in Lake Havasu. Second time it was replaced at the DRV facilties in Howe, IN and the third time was by Lippert at their factory in Goshen. The weight of the slide is just too much for the schwintec system to handle.
When the slide would not operate we were unable to access the bedroom or the bathroom which was until repairs could be made. I will never again buy a camper that does not allow access to these areas when the slides are in.
