Read page 6 here. It seems a Magnum is a combo inverter/converter that sits between shore/generator power and downstream loads. It automatically dials back its AC battery charging demand when AC loads go up. Page 14 explains dropout voltage which is the threshold for switching from inverter to shore and back. The info note at the bottom of page 14 addresses the OP's issue.

Didn't we ask about turning off converters earlier in the thread? Kind of hard to troubleshoot without all the info.

I had turned off the charger off at one point in testing and it didn't make any difference
I didn't realize the issue could be in the inverter so I hadn't mention anything about the Magnum ME2012 inverter. Sorry about that, I've only had this rig for a month and still try to figure it all out.
The drop out settings are explained on page 18

It's all good. Just to clarify, your unit is both a converter (battery charger) and inverter (12v to 120v AC). When the AC input power is good from a shore cord or generator, it charges the batteries along with sending the power to all of your AC circuits. When the AC demand exceeds the supply, it scales back the battery charging. When the AC power input voltage drops too low (dropout level) it assumes the power is insufficient and switches to inverter mode. The idea is to keep AC power inside the camper when outside power goes away without a manual switch. Since the generator was loading down when the A/C started up, the voltage dropped enough to trigger the switch to inverter mode, followed by cutting out since it couldn't power the A/C. Lowering that dropout level allows that temporarily low voltage through long enough for the A/C to spin up and the generator to recover.
