Amazing how many systems in an RV do not protect themselves but rather rely on operator for proper operation.
You think the transfer switch is a no-brainer, check this out. On my ancient 1990 Winnebago, there is a rocker switch on the dash. If you push it one way, it momentarily gangs the house battery to the engine battery for an emergency start. No problems there.
But if you push it the other way, it stays that way, and allows the alternator to charge your house batteries while the engine is running.
BUT if the generator is also running and you do this - it will smoke your vehicle voltage regulator. This is explicitly warned against in the owner's manual. I have accidentally smoked the VR this way before.
You would think there would be some kind of interlock that prevented this situation.
