Your Driving and the Road Towing a Trai/er (CONI) Hitches It's important to havethe correct hitch equipment. Crosswinds, large trucks going by, and rough roads are a few reasons why you'll need the right hitch. Here are some rules to follow: If you'll be pulling atrailer that, when loaded, will weigh more than2,000 pounds (900 kg), be sure to use a properly mounted "weightdistributing" hitch and sway control of the proper size. This equipment is very important forproper vehicle loading and good handling when you're driving. Will you have to make any holes in the body of your vehicle whenyou install a trailer hitch? If you do, then be sure to seal the holes later when remove you the hitch. If you don? seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. (See the Index under Carbon Monoxide in Exhaust.) Dirt and water can, too. The bumpers on your vehicle not are intended for hitches. Do not attach rental hitches or other bumper-type hitches to them. Use only a framemounted hitch that does not attach to the bumper. Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer so that the tongue will not drop to 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. Follow the manufacturer's recommendation for attaching safety chains. Always leave just enough slack so you can turnwith your rig. And, never allow safety chains drag on the ground. to
