1) regarding remote panels. Consider wire gauge for DC voltage drop.

2) Waterproof quick disconnect from RV to the remote panels.
3) gauge of wire between batteries AND to/from 2000W inverter and batteries.
I had a 2000w inverter with 4 gauge wire. It is a 2' run from the batteries to the inverter. Tested 1500W microwave for 5 minutes. Worked fine BUT the wire reached 134°F in that 5 minutes. I upgraded the wiring to 0 gauge.
You will need circuit breakers (disconnects) between the solar panels and the MPPT, MPPT to batteries, batteries to inverter.

ALWAYS DISCONNECT THE SOLAR PANELS FROM THE MPPT BEFORE DISCONNECTING THE BATTERIES.

I am going to wire my forward AC to a switch so I can manually select to run it from the inverter OR the OEM circuit breaker panel. Must be careful not to make a back feed or ground loop.
You will need a "soft start" for your AC.
I have a Victron BMV-712 bluetooth battery monitor. Can monitor it from the house 100' away.
You may want to look at a Victron Multiplus. It combines power from your batteries or shore or PV to run what you are trying to run.
I will Probably go that way eventually.
