Setting up my solar system
I'm in the planning stages of adding solar to my travel trailer. I currently have a battery bank of two 6V flooded lead acid GC batteries in series that is 215 Ah 12 volts. I am planning on adding ...

You're missing an opportunity if you run all 4 panels in parallel. With 4 you will yield a little better if you run 2S x 2P. Your MPPT controller can take better advantage of the higher voltage in all light conditions. You can also downsize some wiring if you choose. No point in having an MPPT if you run them all parallel. No need for any extra breakers IMO, just one to protect, and more importantly to disconnect, the entire array.
Using 24V panels in parallel for 12V battery requires a MPPT controller. PSW works for 12/12 or 24/24.
