the manual that FR provides, is pretty useless and generic.
all it has is basic RV systems explanations.
FR doesn't make any model-specific owners manual, for any model RV that they make.
you're better off buying a RV handbook than using the FR owner's manual.
do a search here, on "owner's manual" and you'll find hundreds of posts saying the same thing.
you can get manuals for the individual items, like the a/c, oven, fridge, converter and so on, from the manufacturers' websites. just get the model number of each and you should be able to download what you need.
