Or what you can do it what I did. I use a 120volt 15amp DPDT toggle switched. This way I go between the inverter and the breaker to selected plugs. Granted there are 30 amp DPDT switches out there and by no means would I used this switch to alternate power for the microwave.

At any rate, if you wish to power the entire AC electrical system from the inverter, using an additional transfer switch, you can put the transfer switch in a few different places, and I think where it ought to go depends mostly on what priorities you would like for the various power sources. I'll attempt to illustrate with rather crudely drawn diagrams.
With just a generator and a shore power connection, the generator typically has priority over the shore power (and a delay before the transfer switch changes over to permit it to get up to speed and under control), like this. I'm using a start to mark the priority input to the ATS.
If you want the inverter to have priority over both the generator and the shore power connection, you can connect the new transfer switch after the existing transfer switch with the inverter having the priority input, like this.
If you want the inverter to have priority between the generator and the shore power input, you can connect the new transfer switch between the shore power input and the existing transfer switch, like this, giving the inverter the priority over the shore power.
If you want the inverter to have the lowest priority, you can connect it similarly to the previous except swap which input to the new transfer switch has priority.
If your shore power cord is permanently attached to the RV and gets stored in some sort of a compartment, I would suggest not getting a transfer switch and instead simply installing a socket in the storage compartment to plug the shore power cord into. That would cost considerably less money, probably be easier to wire, and is not a significantly greater amount of work to use in typical cases as you simply plug the cord in when you stow it.
My personal opinion is that powering the entire RV 120V electrical system from the inverter is rarely the best option. I would rather have selected circuits that are either switched or dedicated to inverter usage. That's personal preference, not absolute gospel truth.
I wanted to thank you for your help and instructional diagrams, they were a big help...chose the inverter installation with least priority. Finished last night. Inverter and generator ATS are working fine. Today will try shore power to make sure everything is ok. Again TY.

Great job in explaining...TY
