Edit- Actually, I see you dedicated a breaker to the onboard charger so you can isolate and turn that off. Found a youtube video of this exact install. I guess the only downside is having to change the shore power cord back and forth from inverter to generator throughout the day.
Thanks again
You got it, converter must be off when doing it this way. I personally have my converter off by default and rely on solar. Converter would be a backup charging method which would then trigger the need to hit the switch.
When we camp in summer heat, then the generator comes along for running the air conditioner. But otherwise, no swapping going on and we're plugged into the inverter for the whole stay.

I ran a thirty amp cord from the inverter to an outlet. I cut the 30 foot cord and added a new male end.
Commonly referred to as a "Dead Man's Cord" or "Suicide Cord". Goes against pretty much every electrical code.
Be very careful following this advice. Even if you are aware and understand the risks, someone else may not be aware and get themselves killed.
You misunderstood. I added a dedicated outlet powered by the inverter. Then I plug the shore power cord into the outlet.
All of my modifications are up to code. It costs almost no extra money to do it safely and correctly.

I did something interesting on my new 5th wheel
It came generator ready, but I chose to not get the gen. I put a 50a plug on the front of the trailer, and tied it into the transfer box. I then mounted a 2200w inverter in the front, tied to s dual 100a LiFePO4 battery bank and attached a 30a cord to it, and added a 50a plug. I turn on the inverter, plug in the connector, and I have 120v throughout the entire trailer. I also added a switch to turn off the charger too.

If you are replacing the 30amp male end with a 15/20amp male end, so you can plug directly into the female outlet on the inverter without an adapter, that's fine.
A cord with 2 male ends (which is what your original post appeared to imply as there was no indication of changing the type/amp rating of male end), is used by some people, so they can just connect the inverter to a convenient outlet near the inverter and back feed power to the AC system. This is dangerous.

What part of dedicated female outlet do you not understand? The inverter powers the outlet. The RV is plugged into the added outlet.
In my particular case the outlet happens to be hard wired to the inverter, using 3 #10 wire rated for 30 amps.
The inverter is 3000 watts and the no load voltage happens to be 123. That means a wire rated for 24 amps would be adequate. However I chose to use 80% load which means using wire rated for 30 amps.
