-Easier than loading a roof mounted box
-Less noise than a roof box
-More fuel efficient than a roof box
-The cargo box separates allowing you to carry the contents to your campsite or hotel
-Have working keys for all 4 latch locks that improve security
-You can remove the box and just use the tray if needed
