A wheel-less cargo carrier or dolly has multiple telescoping or expandable support beams that can remain attached to a vehicle in a retracted configuration when not in use. For use of the wheel-less cargo carrier, the beams are extended and engaged with a floor, fence, or other structural portion of the wheel-less cargo carrier. Telescoping beams can include multiple rails where smaller rails nest within larger rails and slide relative to the larger rails as the beams are being extended or collapsed. The rails can share a common top surface, so that a base or floor of the wheel-less cargo carrier lies on a flat support structure. |
