I thought of a few of the suggestions, but many never crossed my mind. I thank all of you for heading me in the right direction. We did take it to FL and it ran well.. The noise of the motorhome door drove me batty. Thanks to all of you.
If you can't adjust the latch to keep the door from rattling (which there's a very good chance could be done), try strategically putting in some self-adhesive felt bumper pads. I've added some on my bathroom and shower stall doors and a couple of other places and they've eliminated a good bit of rattling.
