Monaco has provided an archives of older manuals however it only goes back to 2001.
Manuals
I would think it should be pretty close to a 2000 model to give you the basic info.
Also, if this is a new to you coach contact Monaco and request the Data Sheet which has most of the component info as far as manufacturer, model, and serial number. This comes in handy when you need to replace or repair. Once you get this start doing internet searches for the manuals for each of these. I've found pretty much all of my component info and have in my archive.
