Problem resolved. As usual I have issues that are extremely rare. The tech support at KMG agreed that it sounds like I have a broken tooth but for it to only chatter in one direction ... no explanation. Solution is to replace the slide out motor assembly. Since Travel Supreme is no longer a source they will sell direct. $388.20 my cost plus shipping. Contact

I swapped the bedroom slide motor with the living room slide motor. Got the living room going as it should. I have to help the bedroom slide in one direction, but I can live with that for now.
