I think they have the shore power as primary and the coach as secondary so when the micro wave comes on the Honda is still the primary because it is sending power to the transfer switch and the coach generator doesn't take over. Camping World thinks I'm crazy for thinking this is the way it supposed to work, but don't get me started on their ass's.
Sounds like you already know where to look for your issue, the transfer switch.
I just want to make sure I under stand how you are running power from your Honda... Are you hooking in the shore power cord to the Honda? If so, you are correct, it should switch over as soon as the onboard genset is running. If you are somehow plugging it into an outlet on the camper and feeding circuits that way, that would be an issue (not saying this is what you are doing, but someone might try that
Here is a good RV Tech Mag article
which may help, even though you sound like you know what the issue is....
