Bathroom vent on North Trail 28BRS

We recently had some windy weather. Was checking on the trailer in storage and I was on the roof, vent cover for the bathroom was riped off. Obviously the wind did it. They dont look very sturdy. Found the cover on the ground near the trailer. Is this something that happens alot, or do I need to replace the cover with something more heavy duty. Thanks

A new cover should be easy to get. Most RV dealers have them....but there are 2 different types. Take off the upper hinge and take it with you. The covers get very brittle over time and it doesnt take much for them to blow away. Do you have a cover over it?? If not, I would get one and install it. That way you will not get any water inside the coach even if the cover goes bad. Wal Mart sells the Camco brand covers.
