Hi,
Make your life simpler. Feed the Magnum from shore power.
Feed the OEM shore power cord from the Magnum. Disable the OEM converter, but leave it in place as a back up.
Or if you must have that sub panel feed it from the Magnum. I disagree about what you plan to run from the sub panel. Unless there is a massive battery bank, and/or a massive solar system, running the air conditioner from the inverter is a poor choice.
The Magnum 3012 does not do voltage support, so protecting the electric motor on the air conditioner from brown outs at a campground will not work, unless the OEM converter is plugged into shore power and the rest of the RV is run from the inverter, using double conversion.
Remember that a 50 amp service offers the RV 12000 watts where as the inverter can only accommodate 3000 continuous (25 amps).
