I submitted this in the Vehicle mounted section then realized it should be put here.

Submitting my design for a first-round review. This is the first time I have attempted to design a system so please critique to help me build a robust and safe system. In the event you find ways to simply the design please let me know.
We purchased a 2022 Toyota Sienna Hybrid for use as our travel vehicle in retirement. The goal is to see the country, not spend too much time in the van, by this I mean be outside by day exploring, hiking, enjoying the outdoors or city sights with only breakfast, lunch and dinners or rainy day stuck in the van. In short only be inside during eating, evening rest, sleeping.
The system goal is to power a refrigerator, and a few other items for up to a 2 night stay in one location, move on driving to the next stop for hours while the house battery recharges. You'll notice I did not in include solar, this could be a mistake, but I prefer to leave the roof space for a cargo carrier but can add later if needed.
I have checked the current that the traction battery sends to the van 12-volt battery. A ten-minute drive with a clamp on amp meter set on max recorded 28.8 amps. I also have monitored the current with the van parked and watched current as low as 8 amps. I am connecting the clamp meter onto the red conductor from the traction battery, if I need to check other locations, please advise. I feel I do need to get gather more data on available current at the 12v battery, I need to know what the average available current is and am concerned the 28.8 amps recorded my only be start up amps. Any suggestions?
A couple of questions.
1) You will notice I included a Victron Isolated DC to DC charger; I was previously advised isolated was the correct one to use but I have no idea why? If a non-isolated charger is a better option or the correct one to use, please let me know
2) When parked with van left in ready, would the van traction battery continue to charge the SOK 206ah house battery as needed? In ready the ICE should start as needed to recharge the traction battery’
3) When parked van turned off, would the SOK battery dray any power from the van 12v battery, not good because the van ICE cannot be started without it.
