1. Turn off the AC and hence no Meanwell load.
2. With portable panels lay them face down or whatever so that there is no load.

I will say again. If you hook several different chargers to a battery system, be it 12 volt 24 volt or xx Volt. so long as all the charging systems are set to the same voltage.. IT IS NOT A PROBLEM. No switching needed, (NOTE This applies ONLY to DC systems) as the one with the highest output voltage wins and gets the job of charging while the others automatically idle or at the very least throttle back big time.
IF you are worried that multiple chargers might exceed the battery charge rate then (for a 24 volt system)
Run multiple charge controllers.. Stage one (All sources) set to like 30-40 volts, these the outputs go to the input of the 2nd stage. Set up for the battreies.. Or alternatevely you can get one that limits current only but .. While I know how to build one, I don't know where to buy one.

So you want to use the truck inverter for 120VAC to the Meanwell in the rig to produce 32VDC which will be connected to the solar controller input to charge the 12V batteries while driving. At other times you'll have solar panels connected to the controller input. And at other times you'll have shore power for the Meanwell. Does that sum up what you want to do?
That raises a lot of questions for me about this working as you expect. But as an experiment go for it and let us know the results.

Thinking some more about this, is there any inherent reason why you couldn't simply connect the power supply and the solar panels in parallel, possibly with a blocking diode or two if you're feeling particularly paranoid? Why have a switch at all?

Careful about using circuit breakers as switch as many are not rated to be used as a switch.
Langir specs says to use in conjunction with switch

I used this one from Home Depot but is not rated for DC. In actual practice of infrequent use it has been fine.
