Planning a new RV Solar install, possible options and looking for opinions.

I have some parts to install on a new 5th Wheel and trying to decide what is a better layout. The parts I have as per my tag, I also have a Tristar MPPT 60A controller (will probably not use this, because I want to shift to an entirely Victron based system and have everything bluetooth to my phone), but I want to add an additional portable ground mount PV for when the rig is parked in the shade (could possibly put it on the roof, there is clearance).
I had the 3 Kyoceras in parallel in an old system (individually fused on the positive legs, because I had ports to add the 4th PV panel, just never got one), it worked well, filling up 4 Vmaxtanks 125Ah AGM's in 24V system for the last 2 years, I could even run the RV's AC for a few hours at a time. But now I will probably go Lithium (that is another question, but thinking TESLA modules, Battleborn, or alibaba prismatics) in at least 1000Ah, thinking 2 of the TESLA's for more bang for my buck, but I may have to come up with a cooling solution.
Thinking of the 24V versions, but not sure what specific Victron Charge Controller and Inverter/Chargers I should get to cover the possible 4th panel (or which panel should I look for, do I need to match Vmp and Imp exactly?). I will probably use the Trimetric 2030-RV as a secondary SoC and get the Victron 712 Battery monitor, unless I can get enough selling it locally when I list the Tristar.
Any obvious things I'm missing or should plan for?
3 Kyocera KU340-8BCA, Victron MPPT 150/100 Tr, Victron 712 with temp sense, 2 Vmaxtanks 12V 125A AGM batteries,
Victron 12V 3000W Multi inverter, want to upgrade to 600-800 Ah of lithium batteries, not sure if Lifepo4 or drop ins.
