Our 2013 340 RK has somthing similar (not as severe). One thing to watch is when putting the bedroom slide IN, The screws that hold the slide in place may start to work out. Alot of them were too short and or stripped when being diiven in by power screwdrivers. Check for this. On another note may I ask you to look at your counter top at the right of the stove top. When the Refrig. slide is OUT, do you see any gap forming between the stationary wall and the counter top?
