In 2003 when I purchased my new 19" boat I wanted to find something to store it in for the winter. I found a this 10x20 canopy at my local Costco. It was a breeze to put together. I have had this canopy now for more than 5 years and its still standing, its a little dirty from the trees in my back yard and has some minor tears but as long as you clean the roof off of snow as you get some substantial snow falls of a few inches it wont collapse. I have had a few neigbors have the same canopy who did not clear the snow or have lost it in a storm in wind. I have been lucky thus far it has held up very well. This canopy has so far saved me approximately 1000 dollars by not having to shrink wrap my boat which would cost me about 200.00 every winter. I paid 169.00. In the summer when my boat is not in it I put the lawn mower and four wheeler and many other items as it is a big storage unit for just about anything.
