Been on the phone. Looking like problem is in the charger/inverter.  When we killed the 30A power to charger/inverter, the microwave started working.  We then turned the inverter off while having the 30A breaker to it on, the microwave worked. 

I was thinking the inverter has transfer switch in it. Just looked at drawing and it is showing a separate transfer switch for just inverter.

There is another 30A breaker in main panel but it was lot labeled. I am now guessing that is going to the transfer switch on inverter output. 

Going to need to get Eddie to find that and check that out,

There could be one.  That drawing I posted is for a 2003, which had a Maverick transfer switch as OEM.  I don't know if Eddie actually has a SurgeGuard branded one, and if so, if it has its own transfer switch.  I thought the '06s used the same system, but now I'm wondering if maybe not.

Fixed!!! So far at least. Spoke with a tech at MOT and finally got everything to work. The shore side contact switch had 120 volts going in and coming out which is strange because it didn't work in the coach. After killing the shore power the tech had me manually cycle the contact switch in and out several times. When I turned on the shore power I got full power to all the outlets and the microwave. He said those contacts get ashy and also will burr when you turn on shore power and it has a load. He suggested turning everything off before plugging into shore then turn on a/c's etc.

I'm guessing it's an amp thing and not just a voltage issue. When I get home I'll take some memory clothe and buff that contacter.

I'll update if anything changes for future reference.

Also huge thank you to @turbojack and everyone for your help.

Thank you Michelle it's the SurgeGuard.  That diagram you posted is very close to my coach.

In thinking about this for people in the future what should be the first thing they check.  As I have thought about this over a large Margarita I have come up with first question that should have been ask.

First question we should have asked is "Do  Both/All  AC's work?" If they both/all work we then know that the coach has both phases into the coach so pedestal, plug, cord reel and main transfer switch work. We then would be more directed to the inverter Transfer switch instead of the main power to the coach.

The transfer switch is an easy check and definitely should have been at the top of the list.  That being said I still can't grasp the fact I had 120 on both legs in and out of the transfer switch. That being said and obviously after the fact. The contacts on the shore side should have been obvious since I had full power on the generator side.  I learned a lot yesterday and I thank you all for your help.  I hope I can return the favor one day.
