Trailer Information
The “Trailer VIN Tag” location on your trailer will be toward the front of the trailer on the tongue
of a bumper pull trailer or on the bunk frame of a gooseneck or fifth wheel trailer.
The trailer VIN tag contains the following critical safety information for the use of your trailer.
2.1.1.1
GAWR
The GAWR is the maximum gross weight rating that an axle can support. It is the lowest of the
axle, wheel or tire rating. Usually, the tire or wheel rating is lower than the axle rating and
determines GAWR.
2.1.1.2
GVWR
GVWR is the maximum allowable gross weight of the trailer and its contents. The gross weight
rating of the trailer includes the weight of the trailer and all of the items within it (such as cargo,
water, food and any other supplies). GVWR is sometimes referred to as GTWR (Gross Trailer
Weight Rating), or MGTW (Maximum Gross Trailer Weight). GVWR, GTWR and MGTW are all
the same rating
The sum total of the GAWR for all trailer axles may be less than the GVWR for the trailer,
because some of the trailer load is to be carried by the tow vehicle, rather than on the trailer
axle(s). The total weight of the cargo and trailer must not exceed the GVWR, and the load on
an axle must not exceed the GAWR.
2.1.1.3
PSI
The tire pressure (PSI or Pounds per Square Inch) should be measured when the tires are cold.
2.1.1.4
VIN
The Vehicle Identification Number
2.1.2
Tow Vehicle
When equipping a new vehicle or an older vehicle to tow your trailer, ask the vehicle dealer for
advice on how to outfit the towing vehicle. Discuss the following information and equipment
with the vehicle dealer.
2.1.2.1
Overall Carrying and Towing Capacity of the Vehicle
Vehicle manufacturers will provide you with the maximum capacities of their various models.
No amount of reinforcement will give a 100 horsepower, 2500 pound truck the towing capacity
that a 300 horsepower 5000-pound truck has.
