The "GVRW" is the Gross Vehicle Rated Weight. That's the most the truck should weigh with diver, passengers, gas, water, oil, and payload, etc. The GROSS weight of the truck. The other numbers are max weight on the front and rear wheels.
They have nothing to do with the curb weight of the truck. Best way to find out your actual weight is to take it to a truck stop with a scale. They'll charge you $15-20 I think to weigh your truck. I might suggest you take everything out of the truck that didn't come with it. Then wait until until the gas tank is almost empty. (gas weighs 6-7 lb per gal) have it weighed. Then gas up.
