Abstract

A hollow compartment is formed in the bottom wall of the present truck bed protective liner and defines a ballast chamber to permit inserting liquid ballast in the ballast chamber when it is desired to provide additional weight on the rear portion of the truck and also permitting removal of the liquid ballast from the ballast chamber when it is desired to reduce the weight on the rear portion of the truck. The hollow compartment is preferably provided by spaced-apart upper and lower bottom wall members extending substantially throughout the width and length of the protective liner and being joined along their front and side edges to the corresponding front and side walls of the protective liner. A rear wall is joined to the upper and lower bottom walls of the opposed side walls of the liner to completely enclose the ballast chamber.
