A wrecker-hoist combination attachment for mounting on the bed of a truck includes an A-frame having one end supported by the truck bed and the upper apex supported by a support member connected between the apex of the A-frame and the truck bed. The A-frame includes a base bar with a pair of lower legs extending upwardly from and removably engaging the base bar. A midbrace removably engages the upper ends of the lower legs and receives the lower end of a pair of upper legs. A pulley assembly is removably engaged in a first position on the upper ends of the upper legs when the attachment is operated as a hoist. Alternatively, the pulley assembly is engageable in a second position on the upper end of the lower legs with the upper legs and midbrace removed for operation of the attachment as a wrecker. The support member is adjustable in length to support the upper end of the A-frame in both the first and second positions. A winch is mounted to the truck bed for drawing in or letting out a cable which extends over the pulley assembly and downwardly adjacent the end of the rear of the truck bed for engaging loads thereto.
