A dolly is disclosed and includes a pair of wheels; a frame mounted to the wheels and movable to an engagement position beneath the forward end of a trailer; a fifth wheel assembly; a mounting assembly and a clamp system. The fifth wheel assembly includes a track and a fifth wheel mounted thereto for movement parallel to a translation axis defined by the track. The mounting assembly connects the fifth wheel assembly to the frame far movement between a raised position, whereat the fifth wheel is positioned to receive the trailer kingpin upon movement of the frame to the engagement position, and a lowered position, whereat the forward end of the trailer is supported on the frame. The clamp system is mounted to the frame and selectively locks same against rotation relative to the trailer, to permit the trailer to be towed from its rearward end.
