The same may be true of different outlets as well. I never had the need to investigate that.
Now I carry a home-made box to test both legs before I plug in.

On my 2006 Apex, the transfer switch will not switch to shore power unless both legs are testing good. I made a box that will allow me to connect 2 120v circuits (either in phase or out of phase - 2 different adapters) to the 50a shore power. I use that at home, but then have to manually manage and monitor electrical usage to work within circuit capacity. I quickly learned to keep a multi-meter and a few basic tools in the coach rather than in the electrically powered smart beds.
I also still have the original Xantrex RS2000. I have a similar issue where the Xantrax "locks up" and the inverter bypass does not work. In other words, the black breaker panel coming from the inverter is dead. The first thing I did was disconnect the very old Solar feed from the original solar panel. This feed was preventing the inverter from completely powering off, even when the battery disconnect was open. The original panel is only producing ~10v and is pretty useless anyway.
The second problem / solution was overheating. With the inverter fully shut down for about 30 minutes (shore power off, solar disconnected, battery disconnected), it cooled off and worked normally after powering everything back on. It looks like the previous owner replaced the cooling fan in the Rs2000 rather than replacing the inverter. That short cut may be at the end of its serviceable life now. I've had to do this procedure a couple times.
