If you mean rvawningsmart.com then I can comment.
I ordered from them last spring. The awning fabric arrived quickly and was exactly what I ordered, no surprises. You can't beat the price!!
The installation was not hard. The only caution I would throw out there is the installation is better with three guys as opposed to two. One on the roof and two on the ground.
The fabric replacement instructions are on the awning hardware manufacturers website.
The awning fabric was heavier than the original and I am very happy with it. Looks fantastic, clean easily and rolls up properly.
My only complaint was that it smelled of new vinyl for the first few uses until it got "aired out". The first two times we deployed it you could smell the "newness" from 20 feet away. Not a bad smell by any means, but a smell just the same.
Would I buy this product again? - yes. Would I recommend to a friend? - yes.
Hope this helps.
