I've been going through some of the camping forums getting ready for the numerous trips we have planned out and figured I'd respond with my thoughts on the Fast Pack Awning. I bought it last year and have used it numerous times. So far, I'm pretty happy with it. The biggest issue is wind. If it is windy, one side will generally be blown down and the other will pick up slightly. This can get annoying at night as you can hear it bumping on the side of the camper. I do intend to try to 'fix' this issue by buying a pair of extending tent poles, staking one end in the ground and securing the other end to the fiberglass pole of the awning.
At first I was worried about the wind damaging it or ripping it out or a wall coming loose, but after using it in moderately windy conditions and some very heavy rain, I don't worry anymore. The one trip my family and I were on we had a very heavy downpour that lasted for an hour and flooded many tents out of the campground. The awning sagged a bit, but never went down too much.
The awning does provide good cover and shade. I can fit my Coleman Camp-Kitchen underneath it and cook in the shade or stay dry if it's raining.
So, bottom line, I'm happy with it. It is expensive for what it is, and I hope to improve upon it with some changes, but I'm happy I bought it. Once you get used to it, it goes up and comes down pretty quick.
On my website, I have a folder dedicated to some camping pictures of my Aliner. If you want to see some of it in real world use, stop by. Pictures of the awning are here on pages 1 and 2: http://www.jonathanhrovath.com/gallery/index.php?album=public/misc-stuff/other-stuff
If you have any questions, feel free to ask. I hope this helps.
