I have had them on 3 5ers and wouldn’t be without them. We were just in a brutal storm in Galveston …. And they did make a lot of noise, but the trailer was rocking and the other noise from the storm was just as bothersome. My point – in normal wind they do not bother me, in terrible storms I do hear them flapping, but I also hear all the other noise from the storm.
And I firmly believe they keep the slide room cooler in the hot Texas heat and they cetainly keep off the elements of weather, bird poop, dust etc.
