The problem was with the initial construction of the RV. Apprently during installation someone forgot to install the forward roller in the floor. As the slide moved in and out the forward part was not supported, so it would start to flex the whole slide. Over time that flexing created all sorts of issues with the slide, the rails, motors, heck even the dinnette window started to bowe.
It wasn't until the repair facility removed the slide completely from the coach was this discovered. IMHO, I think all that wear on the slide without the roller may have tweeked it permanently. Even after all the major components of the slide system were replaced(twice), higher torque motor heck, they even added the 3rd rail to it, it still was having issues!!
Lesson learned, I will never purchase another RV with a giant slide!!
That coach is long gone and is someone else's problem now!!
