Weight of the Trailer
How heavy can a trailer safely be? It should never weigh more than 450 kg (1,000 lbs). But even that can be too heavy.
Speed, altitude, road grades, outside temperature, special equipment, and the amount of tongue weight the vehicle can carry must be considered. See “Weight of the Trailer Tongue” later in this section for more information.
Maximum trailer weight is calculated assuming only the driver is in the tow vehicle and it has all the required trailering equipment.
The weight of additional optional equipment, passengers, and cargo in the tow vehicle must be subtracted from the maximum trailer weight.
Ask your dealer for our trailering information or advice, or write us at our Customer Assistance Offices.
See Roadside Service (U.S. and Canada) or Roadside Service (Mexico) for more information.
