A method of carrying equipment on one side of an ATV having a front top rack, a rear top rack and a foot rest on the one side comprising the following steps: a) attaching a utility box carrying bracket to an outer side portion of the front top rack, the foot rest, and the rear top rack; and, b) mounting a utility box on each of the box carrying brackets. Then equipment may be conveniently carried in and removed from the mounted box. In a preferred aspect of this invention the utility box is generally rectangular in plan view and further comprises a utility box lid hinged to one long top side portion of the box and latched to the other opposite long side portion of the box so that equipment carried in the box is protected from the elements. A lateral side of the mounted box is dimensioned to generally follow the longitudinal shape of the fenders and running board so that the box generally fills the void above the running board and a central portion of the fenders.
