ABSTRACT:
A cargo carrier includes a trailer bed having a rear end raising and lowering structure including a pivotal tail section, said bed being slidingly supported by a carriage. The tail section is operable to pivot in response to fore and aft sliding movement of the bed on the carriage to lower and raise the rear end of the bed relative to the ground. In a modification, a second carriage is pivotally attached to the rear of the first carriage by a connecting frame, and slidingly supports the bed. The carrier also has a front end raising and lowering structure having members attached to the front end of the bed and adapted for attachment to a towing vehicle for lowering and raising the front end of the bed in response to fore and aft movement of the towing vehicle.
