Battery & electrical questions

I have a 2014 Coachmen 21QB on a Chevy 4500 chassis, with an Onan 4KW generator.

*Does the generator have its own starting battery? If so, how is this battery charged? Or does the generator crank off the chassis battery? (I'm assuming it doesn't crank off the house battery, as that would kind of defeat the point of having a generator.)

*Does the generator charge the chassis battery?

*Does the chassis alternator charge the house battery? If so, how well?

*Does the battery isolator switch completely isolate the house battery and chassis battery from each other?

*Does the converter charge the chassis battery when the RV is plugged into shore power?

*On the side of the engine compartment, there is a 200 amp fuse. What is this for?
