Abstract
The invention comprises a seating plate including a concentric swivel leveler to be used for leveling a trailer on an uneven ground surface by inserting a connected trailer jack into the swivel and establishing a stationary position wherein the trailer is substantially level. In certain embodiments, a spacer is also provided with a receiving well for the swivel such that a height of the seating plate above the ground surface is increased such that the trailer jack need not be extended as far as it would but for the spacer. A spacer may be of durable material and includes reinforcing support members help support large loads. In certain embodiments, the swivel may be fastened to the spacer using nuts, bolts and the like so the swivel may swivel about the receiving well while the seating plate maintains a height above the space top to allow for the swiveling action.
