I have a ?. If you are running your gen going down the road for ac, the 110v system in the coach is powered up so the buzz box is charging the house battery and the engine Alt is also. Could this overcharge the house battery?

One, you can turn off the breaker to the BuzzBox or simply unplug it.
Two, get a modern inverter and install a battery combiner.

Could this overcharge the house battery? The battery will charge from the higher of the two voltages. The battery will only get overcharged if one source is too high for it. Think of a water tank with two pumps pushing water into it. It can only get to the pressure of whichever source is higher pressure. If there is no check valve (diode) it will flow through the tank from the higher pressure source to the lower pressure source, and stay at about the pressure of the lower pressure source. With a check valve (diode) on the lower pressure source it will never exceed the pressure of the higher one.
