If you're using a "dead-weight'' hitch, the trailertongue (A) should weigh 10% of the total loaded trailer weight If you have a (B). "weight-distributing" hitch, the trailer tongue (A) should weigh 12% of the total loaded trailer weight (B). After you've loaded your trailer, weigh the trailer and then the tongue, If separately, tosee if the weights are proper. they aren't, you may be able to get them right simply by moving some items aroundin the trailer. Total Weight on Your Vehicle's Tires Be sure your vehicle's tires are inflated to the limitcold tires. You'll find for these numbers on the Certification label the driver'sdoor lock pillar or on see "Tire Loading" in the Index. Then sure you don't go over the GVW be limit for your vehicle. Hitches It's important to havethe correct hitch equipment. Crosswinds, large trucks going by, and rough roads are few reasons why you'll need the right hitch. a Here are some rules to follow: If you'll be pulling a trailer that, when loaded, will weigh more than 2,000 pounds (900 kg), be sure to use properly mounted, a weight-distributing hitch and sway control the proper size. This of equipment is very important for proper vehicle loading and good handling when you're driving. Will you have to make any holes in the body your vehicle whenyou of install a trailer hitch? If you do, then be sure to seal the holes later when you remove the hitch. If you don't sealthem, deadly carbon monoxide (CO) from your exhaust can get into your vehicle (see "Carbon Monoxide" in the Index). Dirt and water can, too. If your vehiclehas a deadweight hitch and a endgate-mounted spare tire, and your trailer has winch ortongue jack, you could have interference a between them. Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under tongue of the trailerso that the tongue will the not drop to the road if it becomes separated from the hitch. Instructions about safety chains may provided by the hitchmanufacturer or by the be trailer manufacturer. Follow the manufacturer's recommendation for attaching safety chains. Always leave enough slack so you can turn with just your rig. And,never allow safety chains to drag on the ground. 4-39
