Unfortunately on many rv's the overflow is plumbed in such a way that once it starts to drain for any reason such as sloshing as you go around a corner, it creates a vacuum and can empty the entire tank.
YES. IF the water really IS coming out a vent/overflow line.
My vent/overflow is a little hole right next to the filler neck.
Mine also has a quick drain valve in the bottom of the tank which also could be the culprit here too.
