I have a 2011 3010HD which we bought about 10 weeks ago with a slam door on the left that hangs up in the process of being opened since day one. I found it to be the shocks connected to the door that let it supposibly come up and hold it in the open position since the bedroom slide prevents the door from opening all the way up verticle like the slam door on the right side. In the process of opening it, you actually have to force it open after it comes half way up itself. It is taken a toll on the hinge attaching the door to the main body so I have disconnected the shock on the right side (looking at the door) and found it to be much easier to open and stay open. I have contacted the the warrenty dept. of my dealer several times (Danville RV in Va.) and last discussion with him was that it appeared that I didn't have the correct shocks attached to the door. Meantime, I continue to get different excuses as why they haven't sent me the correct new ones if in fact they are not the correct ones. Has anybody else had this problem?!?
