Gross vehicle weight rating is simply the maximum allowable weight of an entire vehicle when it's packed up and ready to go -- that includes the weight of the vehicle itself, all of the necessary fluids for operation (gasoline, diesel, oil and so on) and any cargo, passengers and tools. A vehicle's GVWR is calculated by its manufacturer, and you can typically find it in your owner's manual or on the vehicle's doorframe, near the door latch. You might also find your vehicle's GVWR on Web sites that list these numbers.

Curb weight is simply how much the vehicle weighs on its own, without any cargo or passengers. This measurement includes a full tank of gas and any other fluids that keep a car running.

So, a vehicle's payload capacity -- the amount of stuff it can safely carry after you've filled up the tank with gas and topped off all of the fluids -- is just a matter of subtraction.

Gross vehicle weight rating - curb weight = payload capacity

For example, if you have a car with a GVWR of 3,500 pounds (1,588 kilograms), and its curb weight is 3,000 pounds (1,361 kilograms), you would subtract 3,000 pounds from 3,500 pounds.

3,500 pounds (GVWR) - 3,000 pounds (curb weight) = 500 pounds (227 kilograms) of payload capacity

Thanks. I know how to calculate it, but was looking to see if anyone know the manufacturers specified maximum cargo capacity. I do have the GVWR and Front and Rear axle weight ratings. I am going to have the vehicle weighed tomorrow.

I just need to show that we are exceeding the manufacturers recommended rear axle weight rating.

 

Going for AFG?

As a matter of fact I am.:thumb: You have any experience with them?

 

There is a tag in the glove box door that list maxium camper weight - typically what that truck can handle in the bed and still allow for passangers.

 

My super duty gasser was allowed 2450 lbs.
Basically 8800 gvw minus 6350 curb weight
with over 3k In the bed, my overload springs would not even touch.
I have had 3200lbs in the bed, and 800lbs on my hitch ball, easily.

 

I had it weighed yesterday and we are ~500 over the GVWR with my ass and full set of gear in it. We normally respond with two firefighters with gear so that would add approximately another 300lbs.
