Multiple Charge controllers? (System design question)

Looking for advice on system design, that might require multiple Charge Controllers. Here is the proposed design…

5 solar panel on the RV roof, charging 4 LiFePO4 12v, 100ah batteries in parallel. One DC to DC charger. #1 solar panel near the front of the RV. #2 and #3 solar panels near the middle of the RV. #4 and #5 panels under #2 and #3 on a drawer slide, only deployed when parked.

I also have a portable panel that I may want to use on occasion if we are parked in the shade.

Was thinking of putting #1 panel on a separate controller, then swapping it for the portable panel, if parked in shade.

Looks like multiple Solar charge controllers may be supported now, but now finding any recent information.

Roof panels are 430W.

What charging architecture would be best?

Panel specifications at max power, Vmp =33V, Imp= 14A. Portable panel is 220W.

You only need separate mppts if the panels are shaded differently or has different orientations/angles.

For panel #4 and #5, can they be on the same charge controller as #2 and #3, but in parallel? So when #4 and #5 are retracted underneath, #2 and #3 will still charge correctly?

With the 2s 2p. Switch a breaker off to the retractable ones when they are tucked in.
