The wind came up and it started to pour down rain. The wind came up enough that I felt it would be a good idea to go out in the rain and quickly furl my awning. Oh, THAT's interesting - the coach door wouldn't close. Wonderful.
With the awning safely rolled up, I retreated indoors and bungee'd the door shut so the wind wouldn't open it.
It was a short storm, and when it was done I investigated the door problem. Motor-home doors are not made all that well, and this one's been opened and closed since 1992 and judging by the screws and screw holes, it was doing things like this long before I acquired the rig.

One problem is the door is very flexible. That's to avoid excess weight on the vehicle. The other problem is that road vibration loosens screws. When you find loose screws, you have to tighten them. In an ideal world, I would check over screws on a regular basis, but who has time? So when they get my attention, I tighten them.
I didn't take a before picture, but it was immediately apparent that some screw tightening was necessary as the inside of the door handle assembly was not flush against the door. The door panel doesn't tuck well into the part that goes around the edge of the door, either - that's why this is titled upcoming project. But for now, it's working again.
