Ease of Installation
They look nice, but the instructions indicated that you apply them right to the existing bed caps which are plastic. Did that, and I have had to put them back on twice after seeing them looking like they were going to pop off. And its looking like I will have to do it again. Would of rather had pre-drilled holes and a nice bolt securing them down. So yeah, not happy.
