Abstract

Abstract A vehicle transport trailer, which is capable of carrying three to four vehicles and can be hauled by a pick-up truck. The trailer has two levels. The upper level has a rear end portion which is sloped towards the ground and is used as a ramp for loading and unloading. A hitch is attached to the front end of the upper level. A lower level is hinged to the main body of the trailer and is attached to the front end of the upper level by power activated telescoping members which are movable between a first position in which the trailer can be hauled at its hitch by a pick-up truck, and a second extended position in which the trailer is supported by the front end of the lower level and the rear end of the upper level, with the front end of the upper level and the hitch being pivoted upwardly to allow free access for loading and unloading of the lower level.
