Craig, first of all Welcome to the forum!
I think you've found a great source of information.
If you're ever looking for somewhere to camp or someone to camp alongside,the main page has many opportunities to get together with folks in your area....
If you aren't having any luck at the dealer level, perhaps you can try:
Owner Relations email address-- [email protected]
Service Administration-... 1-800-537-1885
I've been working with them with an issue on my coach and I think you will find them ready and willing to help with your door issue.
