How to Convert Oven Recipes to Air Fryer
Safe towing requires checking multiple weight limits. Exceeding any single rating can cause dangerous handling, brake failure, or structural damage — and voids your warranty and insurance coverage.
The basic rule:
- Payload capacity = GVWR minus curb weight. This includes passengers, cargo, AND tongue weight.
- Tongue weight should be 10-15% of total trailer weight for conventional hitches, 15-25% for fifth-wheel.
- Combined weight (vehicle + trailer) must not exceed GCWR.
Always verify your specific vehicle's ratings on the driver's door sticker and owner's manual. Ratings vary by cab style, bed length, axle ratio, engine, and option packages — even within the same truck model.

Frequently Asked Questions
What is GVWR?
GVWR (Gross Vehicle Weight Rating) is the maximum total weight your vehicle can safely carry, including its own weight, passengers, cargo, and tongue weight from a trailer. It's set by the manufacturer and printed on the driver's door jamb sticker. Exceeding GVWR is both unsafe and illegal.
What is GCWR?
GCWR (Gross Combined Weight Rating) is the maximum total weight of the fully loaded vehicle plus the fully loaded trailer. This includes everything: vehicle, passengers, cargo, trailer, and trailer cargo. It's found in the owner's manual.
Why does tongue weight matter?
Too little tongue weight (under 10%) causes trailer sway which can lead to loss of control. Too much tongue weight (over 15%) overloads the rear axle, causing poor steering and braking. Proper tongue weight keeps the trailer stable and balanced.
Does tongue weight count toward payload?
Yes, absolutely. Tongue weight is part of your payload. If your truck has 1,800 lbs of payload capacity and you have 400 lbs of passengers and cargo, your maximum tongue weight is 1,400 lbs. Many people overlook this and exceed their GVWR.
Can I exceed my towing capacity with a weight distribution hitch?
No. A weight distribution hitch redistributes tongue weight across all axles for better handling, but it does not increase your GVWR, GCWR, or towing rating. You must stay within all manufacturer-rated limits regardless of hitch type.
How do I find my truck's actual curb weight?
The most accurate method is to weigh your empty vehicle at a truck scale (CAT scale). The manufacturer's listed curb weight is for a base configuration — dealer-installed accessories, bed liners, toolboxes, and aftermarket bumpers all add weight that reduces your payload.
