Solar: MPPT working with converter?
If my rigs converter handles the shore power/generator charging the battery what’s the best way to tie in the MPPT/solar? A bus bar should do the trick right? Was curious how it works with shore...

When multiple sources for DC feed a load, (your battery), the one that actually supplies the current to charge the battery is the one that is the larger or higher voltage. Even as little as .01 volt is enough to make that source the draw for charging. This is Ohm's Law in action.
Ever wonder how a home's AC solar is selected over the power company's AC? Because the solar senses the power company's voltage and makes it's voltage a little more, so the load, house, draws from the solar and not the power company. It's the same with your DC solar and the AC powered charger in your RV. Some alternators are able to also charge a RV's batteries and it's the same deal; the one with the highest voltage will feed the load.
