Abstract: The invention is a stabilization system for a fifth wheel trailer that prevents rocking and swaying of the trailer when parked. The rear end of the trailer is supported by a pair of adjustable supports that have a top railing joining them. The rail is moveably mounted on the two supports and is secured to the under side of the trailer. Each of the supports is independently adjustable to lower it to the ground. A pair of cross-braces connect the top of one adjustable support to the base of the other support to prevent swaying of the trailer when parked. A tripod type support is placed under the front end of the trailer to support the front end and to eliminate swaying at the front end of the trailer.
