I somewhat agree - as most manufacturers have this same type of 'general' owners manuals due to the many Makes and Models and Floorplans for their factories. Rather than printing a specific manual each and every different exact model, they 'generalize' the owners manual to be somewhat generic to most units, sometimes including information that does not even pertain to your specific model.
Since they ALSO include the specific owner manuals from the products they install, such as the Microwave, the Generator, or even the Schwintec slide system, for operational information, they don't try to replicate these details within their own owners manuals.
If you've purchased an RV lately, you might remember the 'luggage' that all of the owners manuals come in!
I personally would like for them to call me and offer me a job doing exactly this - creating owners manuals for each exact make, model, and floorplan they manufacture.
I doubt they'll be calling, though... : /
