ABSTRACT:
An apparatus for limiting the side sway, or yaw, of fifth wheel recreational trailers when such trailers are parked without being attached to the towing vehicle. Such trailers have a steel housing projecting downward below the front, or cantilevered end. This invention includes two steel tubes, each tube having a pipe tee at one end. One tube is placed on each side of the housing with the teed end in the right angle formed by the housing and the trailer body. The bare end of each tube is supported on a separate baseplate. Each baseplate has a knob projecting upwards. The knob fits partway into the tube, and allows the tube on each side of the trailer to adopt a proper supportive position, almost regardless of the unevenness of the ground. The tubes are connected by a chain which is made and kept taut by a turnbuckle.
