    Abstract: A trailer support stand. The stand includes a base having a plurality of peripheral edges. A series of legs extend upwardly from the base and are connected at their upper ends to a generally flat plate. A ball is mounted in spaced relation above the plate and the peripheral edge of the plate extends radially beyond the outer diameter of the ball. A conventional socket coupling member on the trailer tongue is adapted to be engaged with the ball to thereby support the trailer tongue at trailer hitch height. The stand is non-tipping and when the trailer coupling is locked to the ball, the trailer is theft proof.
