I had the same problem. I replaced the hardware as described previously and took further measures to prevent future damage by making the following repairs and modifications to the entrance door. Because the door had be swinging back greater than 90 degrees for some time the hinges had "opened up" and, thus, were lose and the door listed slightly down toward the latch side. This eventually resulted in the remote door locking mechanism to malfunction. After replacing the the hinges with three new hinges and having to buy a new remote latch mechanism (at a total cost of over $300 for everything) I looked for a way to "hold" the door open so that it would not whip around during sudden bursts of wind. I found that the simple "Rod-Entrance Door" system found on page 171 of the Winnebago Parts Catalog worked just fine for me.

127647-03-01A Rod-Awning Guard, Entrance Door, 19.4”
I was going to mount the retainer eyes up high on the interior of the door and on the frame of the coach, but DW was unable to reach that high, so I mounted one eye on the right bar that holds the rear view mirror and the other on the exterior of the door, just under the window, in positions that would hold the door rigid at 90 degrees when open. I was concerned that a good gust might knock the mirror out of alignment, but have yet to have that problem.
