Problem:

How do I make the following items work together concisely? I want a concise system for my truck camper. I want an all-in-one unit that interface with so it can be used in other applications.

1) I want to have a 200 or 300 AH lithium battery (good quality + good BMS, like a SOK) for extra storage.
2) An all in one unit like an EcoFlow Pro (300 AH) for my AC output/input, solar input, and possible DC output.
3) Power 2 DC items: air conditioner and fridge.
4) Have DC charging from alternator.

What's the most concise way to do this?

Biggest questions:
1) Which battery gets the DC from the alternator as input
2) What do I hook the DC fridge and air conditioner to? (do I just add adapters to them?)
3) Can I easily use the lithium house battery to either pull/push power as needed in conjunction with the all in one? This isn't clear to me.

The fewer adapters/converters/inverters the better. (all done safely of course)

Thanks
