The exterior door on my Argosy is not sitting correctly in the opening. Therefore it is not sealing properly. On the hinge side of the door there is a gap of 3/8" at the top and /1/8" at the bottom. There may be .010" slack in the hinge pins but nothing that would cause the door to "sag" the way it does. The hinges are tight to the door and tight to the frame. I can grab the top right corner of the door and push and pull on it and it doesn't move.
The hinges look like they are made of cast aluminum and have 2 bolts on each hinge holding them to the door frame. I can't tell how the hinge is actually attached to the door.
How does one go about correcting this problem?
