What owners say
Long-term owners of earlier versions praise the fit, the looks and the independent tailgate, and some came back for a second one. The most common complaint is leaking, especially at the front corners by the rear window and at the tailgate end, and a professional install doesn't prevent it: seven owners with dealer or shop installs still describe leaks.
