Has anyone ever done an upgrade to the factory installed roof vent over their bed? The one that came with our trailer (Flagstaff 21 FB) is such a flimsy piece of junk that we can't really use it. If there is any breeze at all, it will rattle and keep you up all night. I don't really want to install a fantastic fan or put a rain cover over the vent. We like looking at the sky at night even though those occasions are few when there is no wind.
