The effect of tongue weight is about 1.5 times the actual weight. Dividing the 900 lbs (408 kg) by 1.5 leaves you with being able to handle only 600 lbs (272 kg) of tongue weight. Since tongue weight is usually at least 10 percent of total loaded trailer weight, you can expect that the largest trailer your vehicle can properly handle is 6,000 lbs (2 721 kg). It is important that you make sure your vehicle does not exceed any of its ratings - GCWR, GVWR, RGAWR, Maximum Trailer Rating or Tongue Weight. The only way to be sure you are not exceeding any of these ratings is to weigh your vehicle and trailer. Hitches It is important to have the correct hitch equipment. Crosswinds, large trucks going by, and rough roads are a few reasons why you will need the right hitch. Here are some rules to follow: • The bumpers on your vehicle are not intended for hitches. Do not attach rental hitches or other bumper-type hitches to them. Use only a frame-mounted hitch that does not attach to the bumper. • Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, remember to seal the holes later when you remove the hitch. If you do not seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. See Engine Exhaust on page 2-39. Dirt and water can, too. Total Weight on Your Vehicle's Tires Be sure your vehicle's tires are inflated to the upper limit for cold tires. You will find these numbers on the Certification/Tire label at the rear edge of the driver's door or see Loading Your Vehicle on page 4-32. Then be sure you do not go over the GVW limit for your vehicle, including the weight of the trailer tongue. 4-44
