I don't believe you will find one. After my factory tour I believe the general theory is they run around like crazy chickens with their heads cut off, not following a detailed plan or blueprint so that every unit is the same.
I believe I've got a handle on it now.
My rig didn't come with a generator but all the connections are there.
I am going to install a 3000 watt inverter and connect it to the 50 amp transfer via the generator connection box in my front bay.
This way I'll be able to run most everything in the rig . I won't run the AC while on the inverter .
Also will have to remember to shut off the converter while on inverter power.
I plan to have four 6 volt golf cart batteries powering the inverter.
