Vehicle trailer system

A vehicle trailer system for loading, transporting and unloading a load, the vehicle trailer system comprising:

• a trailer, arranged along a front-to-back, longitudinal direction, the trailer comprising:
• a trailer front structure for attachment to a towing vehicle;
• a wheeled, trailer rear structure, pivotably attached to the trailer front structure about a side-to-side, transverse pivot axis;
• a carriage mounted for bidirectional travel on the trailer rear structure along the longitudinal direction;
• a carriage hitch carried by the carriage, the carriage hitch configured for coupling to the load;
• a movable arm pivotably carried by the trailer rear structure;
• and
• an arm actuator operably engaging the movable arm to selectively position the movable arm in a lowered position in which the carriage can travel over the movable arm, and in a plurality of raised positions in which the movable arm extends above the carriage.

• a carriage hitch ball carried by the carriage, the carriage hitch ball configured for providing a ball-joint coupling to the load on which the load can rotate sideways;
• a movable arm pivotably carried by the trailer rear structure;
• an arm actuator operably engaging the movable arm to selectively position the movable arm in a lowered position in which the carriage can travel over the movable arm, and in a plurality of raised positions in which the movable arm extends above the carriage;
• at least one user-operable control for operating the arm actuator.
