Abstract: A vehicle attachable cargo rack assembly for transporting firewood includes a frame comprising a base that is rectangularly shaped. A pair of end rails is coupled singly to and extends from opposing end members of the base. A front rail is coupled to a front member of the base and extends between the pair of end rails so that the frame is configured to stack pieces of wood. A hitch attachment that is coupled to the front rail is three point type and thus configured to couple to a three point hitch that is coupled to a first type of vehicle, positioning a user to lift and transport the frame. A shank that is coupled to the base and extends from the front member is configured to couple to a hitch receiver that is coupled to a second type vehicle, positioning the user to transport the frame.
