Coupling To The Tow Vehicle ! WARNING Coupler-to-hitch mismatch can result in uncoupling, leading to death or serious injury. Be sure the LOAD RATING of the hitch ball is equal or greater than the load rating of the coupler. Be sure the SIZE of the hitch ball matches the size of the coupler. A gooseneck trailer will have one or two drop leg jacks for raising and lowering the gooseneck ball receiver. Because several drop leg jack mechanisms are available, the general instructions below may vary slightly from the jack manufacturer’s instructions. If the trailer jack on your trailer does not resemble the jack shown in the figure below, follow the instructions provided by the jack manufacturer. If you do not have these instructions, contact your dealer for assistance. Note: Inspect and lubricate jacks periodically for optimal performance. See the “Inspection, Service & Maintenance” section for service details.
