I've already replaced the 12V battery at the front of the trailer with a 100Ah lifepo4 battery to use for the existing 12V loads.

Let me advise you to work differently with the Muliiplus product line, which I know pretty well (even though I don't have one):
The legacy version you mentioned ('2000w') does not have adequate peak power to handle the reactance of a decent size microwave oven. The current Victron 120 volts Victron '3000' model (5500 peak watts, 3000 continuous) might be OK with that. I use a 3000/600 rated inverter to run a '900 watt' microwave.

On the current model, the battery charge capability is 70A into the "24 volt model" (up to 28.8 volts)and 120 amps into the "12 volts model" (with default voltage up to 14.4 volts).
The "12 volt" capability is roughly 6/7 as good as the "24 volt" capability, it would allow you to avoid the separate battery on the tongue. Running multiple 12v battery packs in parallel requires one additional BMS (about $130 each for the good ones), perhaps providing better redundancy at low cost. The multiplus connect DC battery wires on posts, not bare wire plugs - and 2x 2/0 cables (12v) would be adequate for running your Inverter at full power.

Although the newer '300 models' have better inverter monitor and configuration is still done by the 'legacy' VE bus connector ports (from a PC). Cellphones still cant' be used to control it directly.
