Vehicle Series 3500 Single Rear Wheels 3500 Dual Rear Wheels Hitch Type Fifth Wheel Gooseneck Fifth Wheel Gooseneck Maximum Tongue Weight 1 360 kg (3,000 lbs) 1 587 kg (3,500 lbs) Total Weight on the Vehicle's Tires Be sure the vehicle's tires are inflated to the inflation pressures found on the Certification label on the drivers door or see Loading the Vehicle on page 5‑29 for more information. Make sure not to exceed the GVWR limit for the vehicle, or the RGAWR, with the tow vehicle and trailer fully loaded for the trip including the weight of the trailer tongue. If using a weight distributing hitch, make sure not to exceed the RGAWR before applying the weight distribution spring bars. Do not exceed the maximum allowable tongue weight for the vehicle. Choose the shortest hitch extension that will position the hitch ball closest to the vehicle. This will help reduce the effect of trailer tongue weight on the rear axle. Trailering may be limited by the vehicle's ability to carry tongue weight. Tongue or kingpin weight cannot cause the vehicle to exceed the GVWR (Gross Vehicle Weight Rating) or the RGAWR (Rear Gross Axle Weight Rating). See "Total Weight on the Vehicle's Tires" later in this section for more information. After loading the trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they are not, adjustments might be made by moving some items around in the trailer. Weight of the Trailering Combination It is important that the combination of the tow vehicle and trailer does not exceed any of its weight ratings - GCWR, GVWR, RGAWR, Trailer Weight Rating or Tongue Weight. The only way to be sure it is not exceeding any of these ratings is to weigh the tow vehicle and trailer combination, fully loaded for the trip, getting individual weights for each of these items. 5-62
