Gross Combined
Weight Rating (GCWR)
Represents the maximum weight of both your loaded vehicle and your loaded trailer combined.
Curb Weight
The
weight of an empty vehicle — without payload or driver — with standard equipment, fuel, coolant and oil. It is also known as the vehicle weight.
Gross Vehicle
Weight Rating (GVWR)
The actual weight of the entire Chevy Truck or SUV and its contents, including fuel and occupants.
Axle Ratio
The
relationship between driveshaft revolutions per minute and the rear axle’s revolutions per minute. The most powerful and efficient ratio for each individual vehicle is determined by the frequency and the usual weight being hauled.
Trailer Tongue Weight
The amount of weight put on the trailer tongue to keep it balanced for a safe driving experience.
Gross Trailer Weight
The weight of a loaded trailer.
Fifth-Wheel and Gooseneck Hitches
These are designed for heavy trailering. Located in the bed of the truck, these hitches position the trailer’s kingpin weight over, or slightly in front of, the truck’s rear axle. Fifth-wheel and
gooseneck hitches are most frequently used with travel trailers, horse trailers and other large trailers.
Trailer Weight
Rating
This rating is determined by subtracting the tow vehicle’s weight (curb weight) from the Gross Combination Weight Rating (GCWR). Base vehicle (curb) weight plus 150 lbs. each for the driver and a front passenger is used, so additional passengers, equipment and cargo weight reduce this rating.
