A vehicle-attached lifting device and tool support is provided. The device comprises a dual-rail frame supported in an upright configuration by the vehicle tow hitch, wherein an internal subassembly support frame is positioned between the rails for the purposes of supporting different lifting and tool support subassemblies. Along the sides of the upright frame is a pair of ground support members that extend downward towards the ground to support the frame during operation, preventing the load from compressing the vehicle suspension or damaging the same. A winch controls the vertical positioning of the support frame within the dual-rail frame, which controls the position of a lifting or tool support subassembly. Many subassemblies are contemplated for use with the present invention for the purposes of assisting a user without requiring manual input therefrom. The device can also adjust with relation to the vehicle using different trailer hitch attachments.
