UPDATE: Replaced door latch mechanism today with new one bought from Winnebago. As with most things with a motorhome, it was a bit of a pain, requiring some choice words

. Of course as soon as I get the old mechanism out of the door and get ready to install the new one, I discover that they did not ship a new gasket for the exterior latch plate and the old gasket was not reusable. Clear caulk had to do.
Also, can't understand why they didn't make the hole in the door to access the 7/16" nut on the latch bolt just a bit larger. As instructed, I got the most thin wall 7/16" socket I could find but still had to take a grinder to the socket to make it fit into the opening (are you listening Winnebago??) I was going to enlarge the opening in the door rather than grind a perfectly good Craftsman socket but with the blot in the way, my enlarging bit would not work

.
Finally, I took the opportunity to remove the inner door panel and add some foam and foil insulation to the open spaces in the door. Now instead of the door sounding cheap and hollow when closing, it now sounds like a quality car door when it is closed
