Do you have a picture. I have been looking at a replacement for my MX4. The hail kills them. It looks like the Agricover is a thicker layer of aluminum than the MX4. This is my 3rd MX4 and I really like the cover, just have been looking for something with a thicker layer on top.
New guys, remember when you get your truck you can sign up for "MY GMC" and purchase online and you get 20% off of your first purchase. I used it when I bought this cover and ended up paying Just under $900 for it. It is labeled under a different brand because GMC sells it, but I talked with BakFlip for information on install.
