THEN......
I started generator while still plugged into shore power. AC, lights, and refer were all on. Then lights went out, AC stopped, and refer turned off... and almost all 12V items are dead...except for power slide and the power step.
What went wrong?
I'm not sure I should plug back into shore power???
I checked 12V fuses all appear good.
I checked AC breakers and they did not break. Turned them off and back on.
Is it the transfer switch? I can hear it running before I disconnected it.
Generator runs fine but will not power AC or anything
Where should I start?
I hope I did not fry my entire system:(
Thanks for the assistance.

Either one of those NOT making good contact will not allow for ANY 12V DC from 'Converter' or battery
As for the 120V AC...
opening up ATS and 'exercising contacts (pushing on them) freed them up
Any way you now have 120V AC and 12V DC
Along with a better understanding of your ATS and Converter :B

I think there may be some confusion based on the Shore Tie and Generator 120 Volts AC being "30-amp service" and the 30-amp auto fuse on the 12-volt-DC Converter/Charger unit.
Is your ONAN generator a MicroQuiet, 4KY series? If so, there's a circuit breaker ON the genny itself. Remove the access cover with its two latches. Facing you, there's the Start/Stop Switch. "Around the corner" to the right, lies the breaker, on the side of the panel with the Start/Stop on the Front.
To be ON, the Breaker Handle needs to be pulled toward you.
I'm gonna take a flyer here, and suggest that the Auto Transfer Switch/ATS did it job and threw the shore tie load to the genny. But the genny couldn't handle the surge and tripped that little breaker.
Problem with this logic, is the ATS should have flopped the load back over to the Shore Tie. Unless that was too much surge, too.
Something else I've learned. We have a 31-ft with 15000 Coleman A/C, an ONAN 4KY, and an ATS. Sounds like your setup. If the A/C is running, I can start the generator and it'll pick up the A/C "seamlessly." The A/C keeps running. But when I try plugging into shore tie with A/C running, then shutting the ONAN off, the transfer is ragged, and the A/C loses power for long enough that the compressor stalls on high head pressure.
Doing what I just said isn't a good idea, and I've stopped doing it. Our A/C doesn't have any compressor timeout built in, so I now shut it off before transferring either way, and wait about 10 minutes before re-starting it. Just wanted to point out that odd things happen on connect/disconnect to 30-amp 120 VAC power with heavy loads running.
Something's got your Converter/Charger (OB's third pic) offline. Your Step and Slide are no doubt hard wired right to your Coach (House) battery, and the other stuff you're missing is driven by the C/C unit.

1. I removed the (2) 30A blade fuses from inverter (INTELI POWER 9100 - model PD9160A). Both were good and I reinstalled.
2. I opened up the ATS box (same one as image above - IOTA ITS-30R) and insured all connections were tight. Nothing loose. I pused on contacts several times. Nothing stuck. Closed box.
3. I switched generator 30 amp switch off and back on. It was not tripped.
4. I plugged in shore power. Turned on lights and they worked. Tried AC and all good. Micro, TV amd all 12V items worked as they should.
5. I unplugged shore power. Turned on genny. Waited a minute. Turned on AC and it worked fine.
Everything is back to normal.
What could it have been?
Thanks for the support!

ON THE GEN CONTROL PANEL OR NEAR OUTPUT CABLE

Don't know of a 120V AC auto transfer switch with 30A fuses ??
How many power cords are connected to this device with the 30A fuses?
For a 120V AC ATS there would be ONE from shore power cord, ONE from Generator and ONE going out to MAIN AC PANEL
30A Fuses on a ATS :H
30A ATS
Converter has 30A 'reverse Polarity' fuses for battery/converter protection.

Do shut off the generator.
Do plug into shore power.
Do reset any GFCI outlets.
What make and model is the generator?

3. Are there fuses directly on the inverter/converter?

2. Typically, where are house battery fuses?
3. I know the transfer switch has two 30amp blade type fuses. I checked one and it was fine. I need to check the second one?
Thanks

Next would be transfer switch...may not have swapped to gen side
Turn everything off
Plug into shore power and see if you get AC power
Then unplug shore power----start gen and see if ATS swaps and you get AC power
