An extendible hauling rack is provided to expand the hauling capacity of vehicles with roof racks. A user places the extendible rack's hitch receiver mount over a trailer hitch on the rear bumper of a vehicle and locks the lock on the hitch receiver mount so that the trailer hitch is securely fastened in place. The user then typically removes a sliding pin on a sliding extension on the extendible rack and raises or lowers the sliding extension to the correct height so that the support bars on the extendible rack provide a level surface matching the height of the hauling rack on the vehicle. The user reinserts the sliding pin through a hole in the base of the extendible rack and the height adjustment hole for that height on the sliding extension. A spring-loaded button may also be used to fasten the sliding extension adjustably to the base.
