Within the RV's Main Panel, though, and since all breakers are traditionally only single 120v 3-wire circuits, the Neutral acts as though it does in any other typical household outlet.

So, there is incoming 240v power, yes, but the Main Panel doesn't 'provide' 240v service to any of the single 120v circuit breakers, at least in the typical RV wiring scheme.


I think I have too much time on my hands!! Fun.

And not enough good information. Neutrals do not go to any standard breakers in either a house or RV. And there are no "240" VAC or "120" VAC breakers; 240 VAC are ganged double breakers, one for each hot leg which are connected to the two "hot" busses. Then there are neutral busses and ground busses.
