    4 out of 5

    Excellent tonneau, saddlebag needs work Excellent tonneau, installed easily. LED light strip installed under rail with battery box "stuck" via double sided tape on bed wall in order to access set screws on battery box to change batteries, will see if hotter weather melts the adhesive, cheap compared to the quality of the tonneau. Saddle bag needs work, outer straps serve no clear purpose, velcro flap works loose with any weight...5 lbs in my case... in the bag. Needs stiffener in outside wall of bag as well as ends and bottom for stability. Suggest incorporating a sewn-in sleeve running the length of the support bar, slide the bar into the sleeve, velcro flap becomes secondary anchor...sacrifice removing the bag for structural durability. Undercover customer service rep acknowledged that the bag is not made in house.
