Abstract
A truck extension attachment for increasing the capacity of a truck bed to carry articles which project rearwardly out of the truck bed includes roller means mounted to the truck bed frame, a retractable frame passing through the roller means, a rear cross frame connected to the retractable frame and means for connecting the retractable frame to the rear cross frame. The roller means have one or more roller housings mounted to the truck bed frame with each roller housing having a pair of rollers vertically aligned within the roller housing. In a storage position, the retractable frame lies beneath the truck. By pulling the retractable frame rearwardly through the roller means, the retractable frame is placed in an operational position in which the retractable frame extends partially beyond the rear of the truck bed. The rear cross frame lies parallel to the rear of the truck to support articles projecting from the rear of the truck bed. In an alternative embodiment, an overhead extension attachment similar to the truck extension attachment is connected to the side frames of the truck to carry objects above the truck cab and beyond the rear of the truck.
