Here is the "Sales Brochure" for your model:

This is probably not what you want.
I owned a 2002 Newmar Dutch Star. It came with no manual, instructions, nothing.
What I learned was, there is no "manual" per se'.
So I went and researched all appliances and components from the Internet and started a nice binder. This is the manual for the coach, I hope the new owner appreciates the time and effort.
Now we have a 2017 motor home. It did not come with a "manual" either. It did however come with a large satchel with separate manuals for appliances and components of the motor home.
The 2017 did come with a spiral bound information book put together by Newmar. It is very generic and covers several models of their RVs and contains simple instructions for the different appliances and components. Maybe a call to Newmar Customer Service will get you one of these, In House" publications for your year and model.
Good luck in your research - it is frustrating trying to learn about your coach and you can't put your hands on anything - the stuff is out there - just gotta look.
