I just installed them on the bunk over the cab. I get a lot of wind noise inside the cab. Some guys put air foils on there rigs. It was mention about these air tabs in a older post. I found a local company that carried them so I wanted to give them a try. I hopping it will cut the bugs also. I will keep everyone inform on the results. I might mention they were easy to install I snap a chalk line use my thumb as a spacer. Then you peel the paper off and it has sticky on the back of them. Simple.... ART
