Right, which also means that an autostart on the generator will not help because the 120 VAC output from the generator is fed to the converter, which creates the 12 VDC to charge the batteries.

The OP needs to absolutely confirm that the house batteries are in fact charging when only the generator is running. He earlier stated he thought the batteries were charging from the generator.

He can do that by starting the generator and looking at the converter input voltage. There's either 120 VAC there or there's not. He also needs to look at the battery post voltage just on the generator. He needs to be above 13 volts.

I suspect the batteries are not charging from the generator either which would confirm the blown converter.

Otherwise he has a wiring problem where that converter 120 VAC outlet is directly wired to the generator output instead of to the coach side of the automatic transfer switch.

Another possibility is that he has 120 VAC at the converter outlet only when the converter is unplugged. He could have a wiring problem where a high-resistance connection (such as a bad converter breaker) drops the 120 VAC at the converter outlet when the converter tries to draw power.

I was speaking of my Xantrex RS2000,I assumed others are the same. Assumed got me again. 120VAC may be detected with a VOM, however it will not provide wattage until a load is detected. The Xantrex tests the circuit for a load based on a customizable setting time length to reduce battery drain.
