A portable retractable adjustable cargo rack assembly intended to affix to an existing cargo support system of a vehicle, meaning roof-mounted (but not limited to such), and to deploy to a near juxtaposed position to facilitate loading and unloading of cargo, thereby alleviating the need for vertical assistance or mechanical devices to deploy or secure. The assembly includes roller bearing housings that attach securely to the existing vehicle rack cross-members, and are secured to the portable rack assembly allowing movement over the surface of the pre-existing cross-members from a secured position atop the vehicle to an extended loading/unloading position at a near-juxtaposed position with respect to the plane of the roof of the vehicle-while remaining attached to pre-existing base frame. This invention also includes a clamping device that secures the assembly to the existing vehicle rack atop the vehicle. Two or more telescoping cross-shafts are included in this invention that may be used to secure and/or support cargo while atop base structure. A retractable support brace attached to the cross-shafts can be deployed to rest against the vehicle or telescoped to the ground to give support while loading/unloading. Two shafts or frames, positioned opposite each other, lengthwise with respect to the direction of the vehicle, connecting the roller housing and clamps to the assembly, respectfully.
