I would confirm the engine alternator is working by 1. Turning the merge switch off, measure engine battery voltage, crank engine and set on high idle, measure engine battery voltage again. It should be higher with the engine running.
You cannot assume that because the inverter was running the fridge that the alternator is charging the batteries. The inverter will invert UNTIL it hits whatever value you have the low voltage cutoff set.
Be careful with the merge switch until you find the problem or you could kill all the batteries in the coach.
If you have a bad house battery and you were driving with the merge switch on then you were putting a terrible load on the alternator.
