I searched the internet and was fortunate to fine the Alcocover site. The site was very user friendly, as it guided me through the process of selecting the type of cover I needed, insured that I took the correct measurements, allowed me to pick the material type (based on where it was being stored) and the color, so it would blend with the paint color of our home. Additionally, I needed clarification regarding the tie down options, so I called the 800#. The rep picked up quickly and outlined the differences. After placing my order, I received my order in a timely manner and was very happy with the quality and value of my purchase. I will definitely use Alco again!!!
