Abstract

Abstract A lightweight utility trailer with a lockable enclosure to provide additional carrying space for vehicles having small trunk areas. The utility trailer is closely connected to a towing vehicle by two pivoted, laterally spaced apart attachment members. Two pivoted wheel assemblies allow the utility trailer to follow a towing vehicle's rear end movements, so as to facilitate the parking and the overall operation of the trailer. A unique frame and suspension provides a low mounting for the center part of the trailer body. The trailer body is attached to the frame by slides to allow the trailer body to be in a closely coupled relationship with a towing vehicle during a towing operation, and yet permit the trailer body to be moved apart from the towing vehicle to allow easy access to the vehicle trunk. A low, lift-over, cut-out is provided in the rear of the trailer body to allow easy placing of objects in the trailer body, and removal of the same.
