A truck bed or liner for installation in a pickup truck bed or cargo vehicle exhibits improved electrical charge dissipating characteristics. The preferred embodiment bed is manufactured of high density polyethylene (HDPE) or similar material containing particles of conductive material such as carbon black dispersed therethrough. In a first alternate embodiment, the bed defines a two-layer composite or sandwich. The upper layer of HDPE or similar material includes dispersed carbon black particles whereas the lower layer is free of such particles. A second alternate embodiment of the invention comprehends a bed liner for disposition in a pickup truck or the like wherein the conductive material is dispersed throughout the liner material. In a third alternate embodiment, the bed liner of the second alternate embodiment is combined with the composite conductive and non-conductive layers of the first alternate embodiment. In a fourth alternate embodiment, a bed or liner of HDPE or similar material includes an open mesh fabric or webbing which has carbon black particles dispersed therein. The mesh or webbing is secured to the upper surface of a liner made of HDPE, preferably by autogenous bonding.
