8-56 Driving and OperatingIf a weight-carrying hitch or aweight-distributing hitch is beingused, the trailer tongue (A) shouldweigh 10‐15 percent of the totalloaded trailer weight (B).After loading the trailer, weighthe trailer and then the tongue,separately, to see if the weights areproper. If they are not, adjustmentsmight be made by moving someitems around in the trailer.Trailering may be limited by thevehicle's ability to carry tongueweight. Tongue weight cannot causethe vehicle to exceed the GVWR(Gross Vehicle Weight Rating) orthe RGAWR (Rear Gross AxleWeight Rating). The effect ofadditional weight may reduce thetrailering capacity more than thetotal of the additional weight.Consider the following example:A vehicle model base weight is2 495 kg (5,500 lbs); 1 270 kg(2,800 lbs) at the front axle and1 225 kg (2,700 lbs) at the rear axle.It has a GVWR of 3 266 kg(7,200 lbs), a RGAWR of 1 814 kg(4,000 lbs) and a GCWR (GrossCombination Weight Rating) of6 350 kg (14,000 lbs). The trailerrating should be:Expect tongue weight to be at least10 percent of trailer weight (386 kg(850 lbs)) and because the weight isapplied well behind the rear axle,the effect on the rear axle is greaterthan just the weight itself, as muchas 1.5 times as much. The weightat the rear axle could be 386 kg(850 lbs) X 1.5 = 578 kg (1,275 lbs).
