At first I was hesitant to buy this product and not the GMC brand. The difference was almost $70. Decided to stay on these liners. It appears to be an easy install. My only complaint is that it doesn't fit perfectly. You will have a gap of about 1 inch at the bottom. Considering it saved $70 I'd say I'd just deal with the 1" or even build something to fill that gap. I'll take a picture and post if I remember .
