This (along with the cargo bag) allows us to store small items when we are out and about.  Whether it is bags of groceries or rolls of paper, or tools.  They are easy to get to.  We are still trying to figure how to fasten this side to side so it stays taut, but we will do something there.  Otherwise, we love having this.  If you have the Bakflip cover and had to lower your accessory rails, you have to be selective where it attaches, but no problems there either.
