On a recent trip to the coast here in southern Oregon, I encountered a significant rain/wind storm. Great fun watching the waves crashing on the shore. I discovered water leaking into the bathroom through the manually opening vent (it was closed). The water was some how getting in then dripping down the inside of the vent frame. An inspection of the vent from the outside hasn't uncovered an obvious source. All the screw heads of screws which secure the vent to the roof and the opening lid to the vent frame have latex caps on them. Seems possible that with the magnitude of rain & wind encountered water could be getting under the caps and entering around the screw shafts. I haven't found a crack in the plastic vent frame. Anyone else had this problem and found a source for the leak??
