Perhaps , if you could add more info about your coach . ( Manufacturer and model ) the moderators could move your question to the owners forums , and a member with exact coach can provide better repair info .
When the pocket door track screws fell out on my coach , I had to purchase a 90 degree driver , mount it to a length of 1x2 , then with a magnetic screw bit and extensions for the 90 degree , work inside the pocket to install bigger screws.
Alternative was to cut the panel in the closet beside the pocket , and do the repair through the hole .... that alternative didn't go over with the DW .
