If you want an original owner's manual, they are offered with some frequency on E-Bay -- usual price is $50.00+/-. I believe that photo copied manuals are available from Secretarial Services just as are similar Airstream manuals as follows:
You can get photocopies of owners manual (1964+) and service manuals (1972-1986) from:
Helen Davis Secretarial Services
PO Box 484 Sidney, OH 45365
Prices are about $33 and $70 respectively. After 1986 the Owners Manuals included available service information.

I don't believe that there was a specific service manual for the Argosy trailers. The service manual for similar model year Airstreams would provide valuable service information as the coaches are quite similar from a structural standpoint.
Good luck with your Argosy!
