Larry, sounds as if your not near your unit.
Do you think the door is out of alignment or possibly has a bent door frame. Guess you would notice a frame being bent, but after the weekend I had with Rockin, a little gun shy.

Have you ran a 24-36" (might need longer) straight edge up the frame on the unit and the frame on the door to see if it's out any.
Looked at the door on my unit, It felt very solid. The two areas I would look at is the area where the hinges attach to the doors frame. I took the screws out of the bottom hinge to see how much play there was and how it attached. When I re-fastened the hinge, Had to push it back or move the door's frame out to get the hinge to seat back into a small lip area of the door. The gasket seemed to get in the way also. I would look at the hinge mounting, at the door, and see if there all screwed in some sort of 'same plane'.
Also noticed that the frame of the door has a series of screws running around the perimeter of the frame that attaches the frame to the inner panel makeup. The screws on mine are 'bout 1/2" long. Wonder if slightly loosening them and closing the door and tightening them up again would help.
If need be can post a picture of the hinge/screw/small lip if I didn't explain it well.
Hope something helped.
