I had them on one 5th wheel and would never buy them again. Every time the wind blew a little, they would get to oscillating so bad that it necessitated bringing all of the slides in. Whenever it rained, they would collect water and sag down on to the top of the slide making it difficult to retract. Also leaves would occasionally become trapped between the awning and the top of the slide. I find it easier and less stressful to just clear the top of the slides with an electric leaf blower rather than deal with all of issues caused by the awnings.
