Thanks for the response Waxhead.
The door hangs straight and aligned with the body everywhere but at the top.
The gap at the back in the picture is actually not that large when I have the top panel pulled down where I think it should be. After reading your post and looking at the top panel again I guess the real question is: Should the outward facing lip on the top panel just below where the rain gutter goes be just above the door or should the door overlap it?
At the front of the door it overlaps the lip and at rear the lip is just above the top of the door.
Thanks
Gilbert
