To find the true payload of a truck it is important to do some research. We, at Alaskan Camper, suggest weighing your truck or the one you are planning to buy. It is best to do this with the normal amount of passengers in it. Then subtract that number (scale weight) from the GVWR (Gross Vehicle Weight Rating). This can be found on the door jamb sticker on the truck. In the picture below you will see that GVWR is 11,500 lbs. So let’s say the scale weight of the truck and passengers is 8,340 lbs. Now it’s just simple math.
11500 – 8340 = 3160 lbs
Also remember that certain suspension enhancements, like air bags, do not increase the payload they just make the truck ride level. They do not change brakes, bearings, axles etc.
