A transport trailer structure for carrying vehicles such as canoes and other elongate loads has spaced apart carrier frames supported on a vehicle frame carried on wheels or other surface engaging members. Vertically extending fore and aft guides extend upwardly from the vehicle frame, and slide bearings on the carrier frames are vertically slideable along the vertical guide members to permit the mobile carrier frames to move from positions of loading to positions of transport, and back again for unloading. Collapsable spacers connect the carrier frames, and a cable wind-up and control system connects to the upper carrier frame at fore and aft locations and is operable to draw the upper carrier frame vertically from a lowered position in which loading of the upper carrier frame takes place to a raised transport position in which the collapsable spacers are restored to control the height to which the upper carrier frame may be raised. Each subjacent mobile carrier frame is then loaded and raised incrementally until the next carrier frame is in loading position. Unloading takes place in reverse order as the carriers are progressively lowered to unloading position.
