I saw another post about the 320RS bedroom door. I too had problems there. For one thing, I don't understand why the factory installed such a heavy door. I first thought it was a solid core door until I had to re-attach the snap for the retaining strap because the screw had wallowed out it's hole and was about to come out. Of course, if that thing comes loose, as it did once with me, the door is so heavy that it will break at least one of the roller guides. I also had a problem with the living room TV mounting bracket being attached to the bottom of the upper cabinet with one screw into the cabinet style, but the second screw just into the thin plywood bottom of the upper cabinet. Almost lost my TV. Since this was on my earlier mentioned punch list, my dealer secured it with a hollow-wall anchor and that worked fine.
The factory should take note and start using hollow-wall anchors for attaching things to thin wallboard, etc.
