A collapsible carrier suitable for transporting a load over rugged terrain which includes a support frame assembly formed by at least a pair of spaced apart side frame members located on opposite sides of a longitudinal central axis of the frame. Cross frame members connect the side frame members to define a cargo bed. A pair of wheels located on opposite sides of the cargo bed are each individually supported by support members mounted on a pivot axis which is affixed to opposite sides of the side frame members and displaced laterally outwardly from the side frame members. The wheels are thus pivotable about these axes from a use position, wherein the wheels are parallel to each other, and disposed on opposite sides of the cargo bed to a storage/backpack transport position wherein the wheels are folded over one another and over said cargo bed. The side frame members are formed of collapsible sections that are either telescoped together or pivotally connected to each other. In the preferred embodiment the axes for the wheel supports are located outwardly from and below the cargo bed, thus enabling the wheels to be pivoted against the bottom of the cargo bed, overlying each other. In the preferred embodiment the support members, while being displaced equally outwardly from the sides of the cargo bed side frames, are of slightly different heights thus enabling stacking of the wheels as they are folded into the carrying position.
