This is my second Duck case. What I love about this cover is that it fits perfectly in my regular Silverado cab, the thickness makes it waterproof, and the cover has eight grommets, two in the front and back and four in the middle. This allows you to use the four nylon cords that come with the Duck case. The laces securely fix the cover to the car. The only downside to this particular cover is the two blue stripes that run the full length of the cover. The green parts of the duck cover are three layers, the blue stripes are only one layer. Blue bars are weak points. My first Duck cover lasted about a year as it tore along the entire length of the blue stripes after exposure to the elements. I will look for a similar case without the blue stripes.
