Abstract: A sport utility vehicle cargo area liner is provided which is made of a flexible semi-rigid material such as ABS plastic. The liner has a bottom, two side walls each of which have at their uppermost edges near the wheel well a ledge which fits over the wheel well, and a leading edge and trailing edge. The leading and trailing edges are curved upwardly to allow the liner to easily slide over the sill of the sport utility vehicle cargo area and also to allow objects longer than the liner itself to be placed into the cargo area without the necessity of removing the liner or interfering with the vehicle seats. A stop strap system with a quick disconnect feature is provided to keep the liner safely in place yet it allows the quick removal of the liner. A harness is also provided to secure items in the liner.
