Abstract: A cargo system for use within the cargo area of a vehicle. The cargo system has an elongated crossbar and at least two brackets for supporting the crossbar while it spans the cargo area. The brackets may adapt a roof top storage rack for use in the cargo area or bed of a truck. The brackets may engage standard truck bed components such as D-rings, deck rails, and cleats to secure the cargo system. The cargo system may be positioned anywhere in the cargo area depending upon the positions, i.e., sidewall or bottom, of the supports for the brackets.
