This awning worked great and following the measuring instruction it fit perfectly. Installation was fairly easy admittedly we watched a couple installation videos to ensure we were were doing it correctly. We were able to get it on securely and the fit seems to be tight with no sags or loose fits areas. The awning seems to be well made and something that would last for years on end with proper care and storage. The awning is made of 16 ox durable material that is tripled layered with PVC and talc for sunscreen protection, the middle layers is a polyester high strength wire mesh that adds to the durability and long life. The inner most layer has a PVC coating. The multi layers help with resistant to fading and making clean up easier. We have used the cover throughout the summer and so far so good, it is as good as the day we got it. The awning also provides reasonable protection from rain. I say reasonable because it protects again water falling down not blowing in sideways. This awning is so well made that we are planning on getting another one for our side patio at home. This would be the perfect size to cover patio and protect it from elements. We have priced other awning and found that this one has the very best value. And the feel is compatible to all of the other versions we have seen if not better altogether. The last awning we had it took about 3 years but it was eventually deemed trash. It had faded so badly and had started to crack, I am assuming from dry rotting. This is a really nice solution for our RV and summer time travels. I would recommend this to anyone looking. Overall we are rating this a 10.
