Abstract: A trailer hitch-mounted utility carrier for vehicles includes a carrier member having an upper wall to which vehicle accessories can be attached and a lower wall which is slotted to receive a "ball" type trailer hitch. In one embodiment, a clamping member pivotally connected to the carrier member is pivotable from a nonclamping position in which the carrier can be removed from the hitch to a clamping position in which the clamping member engages the ball to force a lower portion of the carrier into a clamped position between the ball and an underlying carrier support surface. In a second embodiment, turnbuckles exert a force between rear portions of the carrier member and underlying support to clamp a forward portion of the carrier into a clamped position between the ball and another portion of the support.
