A mounting device for a support unit for commercial vehicles includes at least one supporting area, a first fixing area and a second fixing area, wherein the supporting area is configured to absorb the supporting forces in the supporting direction from the support unit or a support tube, wherein the first fixing area and the second fixing area are configured to fix the mounting device to a semi-trailer, wherein the first fixing area has at least one hole, wherein the second fixing area has at least one hole, and wherein the holes are configured to receive a fastener.

A method of retrofitting a trailer having a crank jack with a jack housing and a jack leg into a hydraulic jack includes removing mechanical components from within the jack housing, the mechanical components comprising gearing of the crank jack, placing a hydraulic cylinder within the jack housing, wherein the hydraulic cylinder comprises a main cylinder and a ram piston extending outwardly therefrom as the main cylinder is filled with pressurized fluid, securing the hydraulic cylinder by fastening a top portion of the hydraulic cylinder to the jack housing using a fastener inserted through a hole in a platform positioned within the jack housing, and further securing the hydraulic cylinder by fastening the ram piston to the jack leg using a bolt extending through a pre-existing hole in the jack leg.

A vehicle leveler spacer and method of using the vehicle leveler spacer that may be selectively attached to a retracted leveler of a vehicle, such as a trailer or motor home. The spacer at least partially supports the vehicle upon extension of the leveler to the ground. The spacer includes at least one connector to selectively connect the spacer to the retracted leveler. The spacer may include one or more drain holes. The connector may be a magnet, strap, clamp, or another mechanical connector. The top surface of the spacer may include a rim along its perimeter configured to retain a pad of a leveler. The spacer may form a gap between the bottom surface and a supporting surface, e.g. the ground, when the spacer is connected to a retracted leveler. The connectors enable the spacer to be quickly attached or removed from a retracted leveler of a vehicle.
