Abstract: A dolly assembly for use in towing a disabled vehicle, preferably including a main tube with a dolly wheel mounted at each end, and a method of using same. In one preferred embodiment, the main tube is capable of selective expansion or contraction along its longitudinal axis, to facilitate adjustment and placement of dolly axle assemblies connecting opposed, generally parallel dolly assemblies. Force leveraging mechanisms may be used to aid the selective expansion or contraction of the main tube, such as ratchet or rack and pinion mechanisms. In an alternative embodiment, and for ease in transport, the dolly assembly may be pivotably collapsed along its main tube about either a vertical or horizontal axis.
