Hi Almot,
My power center is under the bed which lifts up. That allows easy access to the breaker panel from behind.
I was often in situations where I wished to use double conversion, where I would plug in only the converter and power the rest of the RV from the inverter.
Here is what I did
Device to be powered--disconnect from breaker panel and put on a heavy duty male plug on the Romex wire.
OEM breaker add some Romex to a female outlet.
Auxiliary shore power cord goes to a female outlet.
This allows me to switch back and forth from OEM powering to Auxiliary powering in ten seconds.
There was room to add female outlets to the wooden back wall of the power center.
I do use a short 18" #12 cord to prevent flexing of the Romex when moving from OEM power to Auxiliary power source.

Because of solar and the Magnum inverter, my default for the converter is unplugged.

Don, you got me interested.
Is this it?
A/C Romex male plug -> Female outlet (where? near breaker panel?) -> breaker disconnected from OEM shore wiring -> Aux shore cord.
And if so, why connecting A/C to its dedicated breaker through the female outlet rather than just leaving this part intact? As long as the A/C breaker is powered by separate cord, and OEM shore wiring is not connected to anything, it looks good to me.
