Hi Bill.
I have never had one and ordered my TC without one. For what I do, it would only be in the way. One time I had to get my Milwaukee Heat gun out to warm the sheet of ice, that had formed on the top of my slide, and then hit it with my hand to break into pieces and brushed them off. There were two other campers with me and they came over to borrow my Heat gun after watching me do my own. They had awnings and the snow had blown/drifted under their awnings and froze. They told me later that when it rains, the wind blows the rain under the awning, most of the time, to make them worthless most of the time. They do like the shade it provides, when the sun is out and it is hot.
For snow and leaves I just sweep them off. I use my TC for many more nights than most people (as you know) and still have never had a leak around the top of the slide or sides, due to rain or snow. I do get leakage from wind storms and dust, in the desert, but don't think the awning would help me there.
Donโt waste your money on an awning.
