A transporting dolly attachable to a vehicle includes a metal frame having a base with a top surface and a bottom surface mounted on opposed peripheral side brackets, a peripheral front bracket and a peripheral rear bracket. A center support member and outer support members are secured to the bottom surface of the base. The center support member is integrally formed as a hitch connector to engage with a conventional trailer hitch receiver. The top surface of the base provides an area to carry cargo. Swivel jacks are mounted on the frame to allow the frame to be raised and lowered, and additionally provide means to move the dolly with an attached demountable handle.
