your question is asked very often and there are many threads on this.
the basic answer is that FR only provides a very basic owner's manual, that covers basic systems on all types of RVs.
it has nothing specific to the model or even brand of RV.
a basic RV book on RVs would be better than what FR provides.
you can download manuals for the important things: a/c, microwave, converter, fridge/freezer, furnace, water heater, radio, slideout, and so on.
just get the model number and check the manufacturer's website.
