Just re-read the above, and while I'm new, I think I have an understanding of what should work, when...
Battery-only: only 12v devices should work - lights, range hood, 12v fridge circuit (if equipped); water pump; water heater (control board); furnace fan; marker lights
Engine running: all 12v devices above along with cab climate control; in-dash stereo; turn signals (head/tail lights and hazards should always work)
Shore power: all 12v devices above along with power outlets; AC; microwave (via power outlet of course)
If 12v devices only work when the engine is running, then there's a problem with your house batteries - you say they're new, so the issue is with the interconnect like I mentioned before.
For 120v devices in the camper (coach), it should not matter if your engine is running or not; that just determines whether the batteries are being charged - that's just 12v stuff anyway.
On shore power, if your power outlets are working but your AC is not, then there's an issue with the AC or the 120v circuit powering it. You say you checked the breakers; you should pull the cover off the AC air intake and check for 120v there.
Like I said, I'm new to this, so I could be wrong...
