What powers what varies from rig to rig... Set your coach battery to STORE - and see what still has power - most likely those will be coming from the chassis battery. (some have found coach batteries still have a drain when in STORE - why I said 'most likely')
Really is little in the RV that needs AC. TVs, Microwave, A/C (assuming propane fridge since a residential fridge unit would have an inverter already.)
I carry a small plug in inverter but have rarely used it. I added a 12v TV and Bluray player in the bedroom, a 12v adapter for my laptop, a few 12v USB outlets. When boondocking, I only start the genny if I need A/C or microwave (neither of which would be practical on inverter in my setup).
As Whirnot suggested - try some camping and see.
Inverter/battery/solar setups vary widely - typically the first question needing answering is what do you expect to draw in watts, and for how long? Then a suitable system can be designed. Of course the price tag follows the amount you need.
