I wonder if the benefits of having slide awnings or not is more dependent on geographic location.
I live in the south central part of our province which is flat land prairies and usually there is a wind of some sort. There are trees in our parks, but more of the leaf variety and not as many of the fir variety with needles.
The dealer and our friends with TT just told us to check the top of the slides for debris before retracting them and if there is to just sweep them off.
Until we purchased a TT and starting camping with it, I wasn't even aware of slide awnings and started to read about them on various forums. I was starting to think, damn I should have enquired about them when we bought the trailer and had them installed. So I started to look for them on the trailers in the parks we were going to in our area.
What I noticed in our area is that there are very few trailers with slide awnings which makes me think in our geographic location they are really not required or emphasized by the dealers. I always check the top of our slides before retracting them and have only had to sweep them off a couple times.
However I could see in our northern campgrounds where there are a lot of fir trees and little wind to blow leaves, etc off that they would be very beneficial.
