charging 12v when gennie is on in my custom mobile office

Hi, I am making a mobile office out of a 7x10' trailer. The plan is to have a few things that can run off a pure sine inverter on 12v deep cycle for when the generator isnt on. The generator is mainly to run the mini-split for when its too hot or cold inside...
I'll be drawing a few hundred watts off the inverter for LED lighting, laptop, a charging phone, maybe the 12" fan... and there's a couple DC direct loads like a little water pump and a 50W car audio amp.
And I'd like the generator to bulk then float the battery when I either need some air conditioning or the inverter (or separate voltage readout) is telling me I need some DC charging.
It seems like my loads will try to draw off a charger if I simply wire one from the AC of the gennie right to the 12v and over-tax it.
My goal is to not interrupt drawing off the 12v system when its needing to be brought back up by the charging system.
Is this possible without say, needing to get into a A & B battery bank setup?
I know that somehow solar/wind/turbine off-grid feeds the bank while people are using the power. How do I best set this up between just my Champion A/C inverter generator and my 12v deep cycle(s)?
thank you for your inputs,
