Abstract
Abstract Recreation and work-type trailers are difficult to maneuver once detached from the towing vehicle even with the conventional dolley wheel in place. This device includes a horizontal main bar with a pair of plates one at each end being mounted to the underside of the main bar by a bolt and spring loaded to give a limited flexibility thereto. A central socket is pivoted to the upper side of the main bar and receives the stem of the trailer hitch. A handle socket is secured adjacent each end of the main bar also on the upper surface thereof and incline upwardly and outwardly therefrom and selectively receive an elongated handle so that the respective end of the main bar can be elevated by the handle and "walked" forwardly or backwardly or sideways as desired thus maneuvering the trailer readily and easily.
