Aug 20, 2014I had a 2011 Winnebago Class A motorhome with the same problem. The overflow line was poorly designed and it dumped most of the water out by sloshing or creating a vacuum/siphon that sucked most of the water out of the tank. I took it to the dealer to have it looked at under warranty and there was not much that could be done due to the location of the tank.
If most of the water in your tank is disappearing is probably caused by vacuum/siphon from having the tank too full. I got around the problem by traveling with the tank 3/4 empty and filling it to the top when I got to my destination.
Good luck!
