There are several folks here with early 90's CC's. Mine is about 9 years newer and although I have all of the manuals, they would probably be of little service.
A little luck, and Country Coach will re-open in a few weeks then you may want to place a call to Jim Cooley who was (do not know if he still is) the man you need to talk to.
I am starting to believe that these manuals are very much like airplane log books.........
