The good news is that those manuals are useless anyway -- the manufacturer of the RV simply staples together the manuals by the makers of the various subsystems (the fridge, the a/c, etc.).
Those manuals are usually available online.
Good luck, and congrats on scoring a Cikira. If I recall correctly, they were made by the family who originally made Shadow Cruisers and who then broke away from Cruiser to focus on the small 139-size models.
