Using VIN Decoder

If you already own a 2021 RAM 3500 truck and want to know the towing capacity, payload capacity, trim, curb weight, axle ratio code, and other information about your truck, you can use a VIN decoder.

A VIN decoder is an online tool that allows you to decode the unique Vehicle Identification Number (VIN) of your vehicle and provides you with detailed information about its specifications and history.

One of the popular VIN decoders is the Dodge VIN Decoder. It’s free and easy to use. Just type your vehicle VIN and get most of the information about your specific model.

Max Tow Package

For those who need even more towing capability, RAM offers the Max Tow Package.

This package includes a 30K Fifth-Wheel Hitch, the Fifth-Wheel/Gooseneck Prep Group, Auto-Level Rear Air Suspension, Cargo-View Camera, Trailer Brake Controller, Daytime Running Lamps (DRLs), and DOT Safety Kit.

With this package, the RAM 3500 can tow up to 30,000 lbs for fifth-wheel applications and up to 37,100 lbs with a gooseneck.

Important Notes

Gross Axle Weight Ratings (GAWRs), Gross Vehicle Weight Ratings (GVWRs), and Gross Combined Weight Ratings (GCWRs) are crucial for safe towing. You should never exceed these ratings to prevent accidents and damage to your vehicle.

Drivetrain Options:

The 2021 RAM 3500 offers two drivetrain options:

  • 4×2 – Lower towing capacity than 4×4
  • 4×4 – Higher towing capacity than 4×2

Cab Configuration:

The 2021 RAM 3500 offers three cab configurations:

  1. Regular Cab – Higher towing capacity than Crew Cab and Mega Cab
  2. Crew Cab – Lower towing capacity than Regular Cab and Mega Cab
  3. Mega Cab – Lower towing capacity than Regular Cab and higher than Crew Cab

Payload Calculation:

  • Payload is calculated by subtracting the Curb Weight from the Gross Vehicle Weight Rating (GVWR). (Payload = GVWR – Curb Wt.)
  • Note that in some cases, the payload value may be rounded down to the nearest 10 pounds.

Maximum Trailer Weight:

  • The maximum trailer weight is the weight that can be safely towed by the vehicle.
  • Note that in some cases, the maximum trailer weight may be rounded down to the nearest 50 pounds.
  • Payload and maximum trailer weight are mutually exclusive, meaning that if the maximum payload weight is reached, the maximum trailer weight should not be exceeded.

GCWR Calculation:

  • Gross Combination Weight Rating (GCWR) is a defined value in pounds.
  • Base weights may change due to a production audit or product change.
  • GCW can be calculated by adding the base weight, driver weight (150 pounds), maximum trailer weight, and 20 pounds. (GCW = Base weight + 150 lbs (Driver weight) + Max Trailer + 20 lbs)

Recommended Tongue Weight:

  • For a conventional hitch, the recommended tongue weight is 10-15% of the gross trailer weight.
  • The maximum tongue weight for Class V (the receiver hitch) is limited to 1700 pounds.
  • For a Gooseneck and Fifth wheel hitch, the recommended tongue weight is 20-25% of the gross trailer weight.

Hitch Requirements:

  • A fifth-wheel is required for trailers over 30,000 pounds.
  • A gooseneck hitch is required for trailers over 37,100 pounds.

GVWR and GAWR Limitations:

  • It is important to note that the Gross Vehicle Weight Rating (GVWR) and Gross Axle Weight Ratings (GAWR) should never be exceeded.
  • The GVWR is the maximum weight that the vehicle can carry, including passengers, cargo, and fuel.
  • The GAWR is the maximum weight that each axle can support.
