Abstract: A modular rack may feature top and bottom cross-beams mounted upon a central vertical post. A hitch structure may allow the rack to be mounted to a vehicle. Many stowage modules may be added to the rack, including a plurality of adjustable baskets for bicycles, a roof-rack simulator, a table and a hammock. A floor stand may receive the hitch structure and may allow of vehicle storage or storage in a truck bed. The baskets may be vertical or they may lean to one side to accommodate bicycles more efficiently. All modules may be positioned anywhere along the length of the cross-beams.
