This is by far my favorite tonneau cover I have owned. I have had a Bakflip in the past, I had a revolver X I liked it as well but this MX4 is a great cover, light and easy to install. I also love the fact that I can tow my fifth wheel with the tonneau cover unfolded all, but one section so I can utilize my rear window while in tow.
Installation was pretty fast and straightforward. Had trouble with the final stretching and latching of the top. Latching mechanism is not worth of this top. Just sufficient. Winter install here in Michigan. Had to heat my garage and put a bathroom space heater in the truck bed and close the tailgate for about an hour. Finally latched into place. Would have been a lot easier on a hot summer day.
