Hitches It is important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why the right hitch is needed. Safety Chains Always attach chains between the vehicle and the trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. For trailers up to 2,000 lbs (907 kg) safety chains may be attached to the attaching points on the bumper. For heavier trailers, follow the trailer or hitch manufacturer's recommendation for attaching safety chains. Always leave just enough slack so the rig can turn. Never allow safety chains to drag on the ground. Weight-Distributing Hitches and Weight Carrying Hitches A step bumper hitch can be used for trailers up to 2,000 lbs (907 kg) total weight, and 200 lbs (90 kg) tongue weight. Notice: If a step-bumper hitch is used, the bumper could be damaged in sharp turns. Make sure there is ample room when turning to avoid contact between the trailer and the bumper. 5-53
