Abstract: A rack of unitary one-piece construction for mounting to a vehicle is disclosed. The rack may be made of plastic, and may be manufactured by injection moulding. The rack may be mounted and fastened to and fastened to a truck bed. The rack protects the rear window and the roof of the truck cab when the rack is mounted to the truck bed. A connector that is received in a stake pocket and fastened to a rail of the truck bed may be used to fasten the rack to the rail of the truck bed. The injection-moulded one piece plastic rack may allow for flexibility of ease of installation and uninstallation at leisure. Line of sight from the cab through the rear window may be provided with the rack mounted to the vehicle. The load supported by the rack may be distributed to its base.

Abstract: A skirt panel is provided herein for interconnection to another abutted similar skirt panel for attachment beneath a lower, outer longitudinally-extending edge of a trailer including a rear wheel assembly of a tractor-trailer rig, thereby to provide a continuous fairing extending downwardly from the trailer. The skirt panel includes a monolithic, generally-rectangular composite reinforced thermoplastic structure, having vertical lateral side edges configured and arranged for connection to associated vertical lateral side edges of abutting similar skirt panels. This provides a longitudinally-extending fairing for extending contiguously on each side of the trailer, a front face of the thermoplastic structure being provided with a plurality of longitudinally-extending, vertically-spaced-apart arcuate protrusions. The outer face of the thermoplastic panel preferably also is provided with dimples.
