I can shed some light on the "buddy plug" wiring that started with an 89 and included 2000, & several newer coaches. They have all been wired alike.
The total description and you already know most of this:
Shore and generator inputs merge at the XFER. The output of the XFER feeds into the (circuit breaker panelboard) AKA "panel" through a two pole 50A breaker. The buddy plug is fed from taps (connecting to the main lugs of the panel) and is therefore protected by the same 2 pole 50. Ordinarily, (if it was under the National Code Jurisdiction) you would feed the into the panel with the output of the XFER connecting to the main lugs and subfeed the buddy plug with the 2 pole 50.
Newell is smart! Their arrangement allows you to to reset the breaker in the panel if overloaded and additionally protects the #6-4 cable that runs from the panel to the XFER. If wired per NEC, the buddy plug load plus the coach's load are now protected by the feeder breaker (either gen or shore). If you are on generator and loads increase to trip point you'll have to roll out the gen to get to the set's breaker, Newell's method lets you go to the closet. Pretty smart if you ask me.
Another reason I really like a Newell!
