Worth knowing about the 2022 3500

  • LED lighting. The license plate is a sealed LED unit with no user-replaceable bulb. A failure means replacing the assembly.
  • Bulbs. Codes are for halogen reflector headlamps; the manual lists a W21/5W for the base tail and backup lamp, and LED packages are sealed.
  • Wheels. Single-rear-wheel trucks take 130 lb-ft on cone nuts and dual-rear-wheel trucks 129 lb-ft on flat-face nuts, per the owner's manual.
  • Fuel. The Cummins diesel version runs on ultra-low-sulfur diesel, and tank size depends on cab, bed and engine.
