My pole awning is permanently attached to the trailer. I made a pole frame for it that works very well. In high winds where my friends with their awnings have had to roll them in mine stays up. I do supplement the poles with ropes when wind is part of the equation or if we are going to be away from the trailer for a while as we never know about wind coming up. It works very well and my neighbor who bought my Silver Streak did an updated version of mine using the elbows one finds on boat tops that fold up and out of the way. His is much cleaner looking in how the poles fold up as part of rolling the awning up, but what we really like is that nothing needs to go into the trailer, it is all folded up nicely in the awning. I will probably update the two poles on mine that don't have the elbows and add a center pole which he has done having looked at mine to determine what improvements could be made. He did a great job.
I can put mine up and down alone in less than ten minutes but with my wife or a helper it is less than five as there is not the hassle of sliding the awning into the rail. It rolls up nicely and is not intrusive although I'd build a silver one next time rather than the blue. Mine does not have the scallops but I intend to have them made up with either snaps or velcro and include in that a way to hang my awning lights.
I've thought about a Z-D and like the simple set up and take down but I love the look of a vintage awning. I guess a snap on set of scallops would also work on a Z-D if a person wanted them. I've yet to figure out the best way to do that (snaps or velcro) but I've got a buddy who is a retired upholsterer who I'm going to tap for his knowledge one day when he's not too grumpy
