Yesterday they put a loop of tubing in the vent line that went above the tank then down. Gave me the coach back and said all would be good. No way it could siphon with a loop above the tank.
The way it appears now the tank is somehow pressurized.
Sounds like Winnebago doesn't understand a siphon. With a siphon it doesn't matter if they run a loop up high if the exit end is lower than the surface of the water. However if Winnebago had taken an extra step to cut or poke a small hole in the tubing at the top of the loop, then a siphon would be impossible. If worried about bugs glue a small piece of mosquito netting over the hole.
Based on your experience at the campground I would say the tank is somehow pressurizing. It would have been interesting to know if the flow would have stopped if you removed the fill cap to relieve any possible pressure.
