All parts came in undamaged. Instructions for installing were pretty simple but you had to read them carefully. Really an 2 person job but was able to install by myself., just took a little longer. Everything fit great. Am very satisfied with the product!!
Thank you Tonneaucovered .

so far I like the look of the cover, sleek, smooth, not orange peely.easy install, one broken plastic clip for the arm braces, but no big deal. looks great, operates fine. My only mummer is Undercover will not allow you to drive with the top up, as in other brands, and the braces are only long enough for the folded cover to stand straight up and not rest against the back of the cab. I find this odd, when other covers allow you to brace it against the cab and drive. My question is: why would I need to put it all the way, if I were not purchasing/hauling large product that requires max headroom/truckbed space, and I need to get home or wherever. To have it wide open means I need to transport and they say no. so that's a limitation that bothers me, otherwise it stays down and I like the way it looks.
