A load-bearing system configured to rotatably support heavy cargo loads supported from a vehicle, the system configured for attachment to a frame of the vehicle, the system comprising:

• a pivot platform coupled to the frame of the vehicle and comprising first and second swing arms pivotably mounted to the pivot platform, each swing arm in the first and second swing arms comprising a first end coupled to the pivot platform and a second end coupled to a mounting platform, the mounting platform rotatably mounted to the second ends of the first and second swing arms, the mounting platform configured to permit attachment thereto of one or more cargo carriers that are configured to support cargo thereon or therein;
• and
• a locking assembly coupled to the frame of the vehicle and comprising a lever pivotably mounted to a plurality of linkage arms, the locking assembly configured to detachably couple to the mounting platform;
• wherein the lever of the locking assembly pivotably adjusts to a first position to lock the mounting platform into a first position against the vehicle, wherein the lever of the locking assembly pivotably adjusts to a second position to unlock the mounting platform and permit rotation of the mounting platform away from the vehicle so as to expose the portion of the vehicle blocked by the mounting platform when in the first position.
