  • Cooling capability on a prolonged highway ascent modeled on a Davis Dam class on Arizona SR 68;

New calculations for trailer weight ratings: In further to a opening standards, SAE J2807 also uses a specific set of assumptions to calculate limit trailer weight ratings:

  • For light-duty full-size pickups (GVWR 3,855 kg. / 8,500 lbs.), SAE J2807 assumes that a draw car includes any options with aloft than 33 percent penetration;
  • It assumes there is both a motorist and newcomer in a vehicle, any weighing 68 kilograms (150 pounds);
