This disclosure describes a work site utility carrier that configures into a dolly and hand truck in its retracted mode and a work bench in its elevated mode. A lower receptacle formed as part of a chassis with wheels, and an upper receptacle are pivotally connected by a unique positioning apparatus. In a retracted position the two receptacles lie side-by-side with their top surfaces essentially planar. In this mode, the carrier serves as a dolly or a hand truck. In the elevated mode the second receptacle pivots up to station securely above the chassis, The top of the second receptacle becomes a work bench. The receptacles may comprise tool boxes. One or both tool boxes may include tool drawers. Unique latching mechanisms positively secure the carrier in either mode. The latching in an elevated mode is aided by the weight of the upper receptacle.
