Abstract: The present invention is a trailer tongue that can be rolled to an extended and retracted position. The present trailer tongue comprises a housing having and interior portion and an exterior portion. At least one track is located along the interior portion of the housing. In a particularly preferred embodiment, two tracks are welded to on the interior portion of the housing. The trailer tongue further includes a rollaway mechanism that preferably includes at least one wheel for rolling along the track. In a particularly preferred embodiment, the rollaway mechanism includes two wheels for rolling along the tracks welded to the interior portion of the housing. The wheels are positioned to cooperate with the tracks so that the slide mechanism rolls easily along the tracks from an extended position to a retracted position.
