Payload capacity is the single most important number when matching a camper to your truck. Get it wrong, and you risk safety issues, warranty voiding, and a miserable driving experience. Get it right, and you'll enjoy worry-free adventures for years.
What Is Payload Capacity?
Payload capacity is the maximum weight your truck can safely carry in and on the vehicle — that includes passengers, cargo, tongue weight from a trailer, and yes, your camper. It's calculated with a simple formula:
Payload Capacity = GVWR − Curb Weight
Key Terms Explained
GVWR (Gross Vehicle Weight Rating)
The maximum total weight your truck is designed to handle — including the truck itself, all passengers, cargo, and the camper. This number is set by the manufacturer and can be found on your driver's door jamb sticker. Never exceed this number.
Curb Weight
The weight of your truck as it sits in your driveway with a full tank of gas and all standard equipment — but no passengers or cargo. This number varies depending on your truck's configuration: cab size, bed length, engine, 4WD vs 2WD, and optional packages.
Dry Weight vs. Wet Weight
Camper manufacturers typically advertise dry weight — the weight of the camper with no water, propane, batteries, or gear inside. Real-world wet weight (also called loaded weight) is almost always 500–1,000 lbs heavier once you add:
- Fresh water (8.3 lbs per gallon)
- Propane tanks (20 lbs each when full)
- Batteries (40–70 lbs each)
- Personal gear, food, clothing, tools
- Optional accessories (solar panels, awning, etc.)
Pro tip: Always plan for wet weight, not dry weight. A good rule of thumb is to add 15–25% to the manufacturer's dry weight to estimate your real-world loaded weight.
How to Find Your Truck's Payload
- Door jamb sticker: Open your driver's door and look for the yellow and white sticker. It lists your specific truck's GVWR and payload capacity. This is the most accurate source because it accounts for your exact configuration.
- Owner's manual: Lists payload by configuration, but may not match your exact build with options.
- Manufacturer's website: Build-and-price tools often show payload for configured trucks.
- Weigh your truck: For the most accurate curb weight, take your truck to a CAT scale (common at truck stops). Subtract that from your GVWR for true available payload.
The Payload Math in Practice
Let's walk through a real example:
| GVWR | 7,050 lbs |
| Curb Weight | − 5,150 lbs |
| Available Payload | = 1,900 lbs |
| Driver + Passenger | − 350 lbs |
| Camper (wet weight) | − 1,200 lbs |
| Remaining Margin | = 350 lbs ✓ |
In this example, the truck has 350 lbs of remaining margin — enough for a dog, some extra gear, and a safety buffer. That's a good match.
Safety Margins Matter
You should aim for at least 10% payload margin after accounting for the camper's wet weight and passengers. This gives you a buffer for:
- Items you forgot to account for
- Extra water or supplies for remote trips
- Passengers you didn't plan for
- Emergency supplies or recovery gear
What Happens If You Exceed Payload?
- Safety: Braking distance increases dramatically. Steering becomes unpredictable. Tire blowout risk increases.
- Warranty: Most truck warranties are voided if the vehicle is operated over GVWR.
- Legal: In many states, operating over GVWR is a traffic violation. If you're in an accident while overloaded, insurance claims can be denied.
- Wear: Accelerated wear on suspension, brakes, transmission, and tires. What should last 100k miles might fail at 50k.
