When I purchased my 2001 Monaco Dynasty in 2007 from a dealership there were no manuals included with the RV. Being around heavy equipment all my life and enjoy doing my own maintenance and repairs, I personally contacted Monaco Parts Dept by phone and purchased an Owners Manual and Electrical Schematics.
Having reviewed these in detail, the Owners Manual is quite general, but does have some very good basic information about operation of some of the components used in your RV.
The Electrical Schematics are priceless and are absolutely necessary if you want to really understand how electrical circuits all tie together to make your RV perform as designed and built.
As a side note, I would inquire if they have an air schematic/piping diagram, especially for the brake circuit.
Hope this helps your troubleshooting efforts.
