A tow truck is disclosed equiped with an improved body assembly, underlift assembly and lifting boom assembly. The body assembly includes a left body unit and a right body unit. Each body unit has a structural unit and a plurality of exterior panhed to the structural unit. The structural unit is preferably formed from flanged aluminum panels that are attached by adhesive. The improved underlift assembly comprises a support arm coupled to the vehicle. A base is coupled to an end of the support arm, a boom base is pivotally attached to the base at a first pivot point and a boom is pivotally attached to the boom base at a second pivot point. A first actuator is coupled to the support arm and the boom base. The operation of the first actuator pivots the boom base with respect to the support arm. A second actuator is coupled to the boom base and the boom. The operation of the second actuator pivots the boom with respect to the boom base. The first actuator is used to position the boom during lifting operation, and the second actuator is used to position the boom into a folded rest position. The improved lifting boom includes two lifting hydraulic actuators that are coupled to the lifting boom on each side and angled inward to provide improved stability.
