A heavy-duty all-terrain convertible hauler unit is provided which can be converted into various different configurations for hauling a wide variety of different kinds of cargo and material. This hauler unit includes an elongated chassis having first and second ends. A dolly-type load-support spade is attached to one end of the chassis and a pair of relatively large diameter rubber-tired wheels are mounted on the chassis at this same end, but on the side opposite the load-support spade. A longitudinally-extending handle member is mounted at the second end of the chassis when the hauler unit is used as an upright-type hand dolly. This handle member may instead be mounted on the load-support spade in a vertical position when the hauler unit is used as a horizontal-type cart. A third wheel is mounted in the center of the chassis at the second end of the chassis when the hauler unit is used as a horizontal-type cart. A pair of elongated panels are mounted on the chassis in different selected orientations to accommodate different kinds of cargo.
