Can rough roads create a suction from the water tank vent?

I have been driving some windy and hilly roads on Highway 101 on the Oregon Coast with the MH, and it seems that I have lost water from the water tank. Can surging water in the tank leak out the vent...

The vent tube is connected to a nipple at the top of the tank - no way it could suction the water out, but it is an outlet for sloshed water. I have a tapered plastic plug I use to plug ours while underway. We still have some loss as the fill is a couple inches higher than the top of the tank, and the fill cap doesn't seal very well.

Could be what you are experiencing on rough & curvy roads too.
