How it works
In plain English, three steps. Payload capacity is GVWR minus curb weight — the most weight the vehicle itself may carry. Payload used is passengers weight plus cargo weight plus tongue weight, because all three press on the vehicle. Payload remaining is capacity minus used. A negative remaining number means the vehicle is overloaded as loaded.
Example: capacity is 7,050 − 4,700 = 2,350 lb. Used is 350 + 200 + 1,200 = 1,750 lb. Remaining is 2,350 − 1,750 = 600 lb.
Frequently asked questions
Does tongue weight really count as payload?
Yes. The trailer's tongue presses down on the hitch and the tow vehicle, so it uses payload just like cargo in the bed does.
What counts as curb weight?
The vehicle with standard equipment and a full tank, before passengers and cargo. Your door sticker's payload figure already reflects your exact configuration — use that to cross-check.
What if payload remaining is negative?
The vehicle is overloaded as loaded. Remove cargo, lighten the trailer's tongue load within its safe range, or use a vehicle with a higher payload rating.
