Abstract: Apparatus for stabilizing recreational vehicles and the like while in stationary use, providing increased lateral stability and improved ease and rapidity in installation and removal, comprising two legs pivotally connected to a horizontal support member and extending longitudinally downward therefrom to engage the ground. The legs diverge outwardly with respect to one another and the horizontal axis of the vehicle frame and are connected near their lower ends with means for applying a pulling force from one support member to the other so as to pull the two support members towards one another and to provide tension between the support members and prevent them from separating while in use.
