Absolutely! This was designed to work best when pulling 5th Wheel Trailers as many of our customers pull them. When you don’t have your 5th wheel connected, your truck bed is as secure as a trunk with easy access to all areas of your truck bed. However, when you want to hook up the fifth wheel, you simply fold the cover up all the way up and against the rear cab (window) of the truck. Hook up your 5th wheel or Gooseneck trailer and you are ready to go! Once you get where you are going and disconnect the trailer, unfold the cover and return to the fully closed position and you have a secure trunk again.
