This item was far and away the cheapest, most flimsy product I have had the misfortune of ever purchasing. It was impossible to reinforce to any degree that was comfortable in even the slightest breeze, it was constantly banging against the side of our RV. I do not recommend this product at all. The one I purchased is currently in the back of my truck headed to the dump after 1 week of use! DO NOT BUY!
