Systems, devices, and methods for a towable mobility device and/or cargo lift for a vehicle

A towable mobility device lift system for lifting and transporting a mobility device, the system comprising:

• a frame having a front end, a rear end, and a top side positioned between the front end and the rear end;
• a hitch connector positioned at the front end of the frame and configured to removably attach to a trailer hitch of a vehicle;
• a trailer hitch positioned at the rear end of the frame and configured to removably attach to a hitch-mounted accessory or a trailer;
• a plurality of wheels rotatably coupled to the frame such that the towable mobility device lift system may be towed by the vehicle;
• a platform configured to hold the mobility device and having:
• a stowed position for transporting the mobility device, the platform being positioned above the top side of the frame when in the stowed position, and
• a deployed position for loading or unloading the mobility device from the platform, the platform being in contact with a ground surface on a left side or a right side of the towable mobility device lift system when in the deployed position;
• and
• a multi-linkage lift arm having a proximal end coupled to the frame and a distal end coupled to the platform and configured to move the platform between the stowed position and the deployed position.
