Truck Camper Payload Calculator
Most truck owners have never done this math — and dealers won’t do it for you. Pick your truck, describe your camper and load, and see in seconds whether your rig is safe, tight, or overloaded.
Your truck
Payload auto-fills from our database (typical values). For your exact number, check the yellow Tire and Loading Information sticker on your driver’s door jamb — it beats any database.
Your camper
Use the manufacturer’s dry weight — we’ll add the real-world extras below. (Dealers advertise dry weight. Nobody camps dry.)
People and gear
Food, clothes, chairs, tools, recovery gear, the dog — it adds up fast. When in doubt, overestimate.

Payload questions, answered
What is truck payload capacity?
Payload is the maximum weight your truck can carry in the cab and bed — passengers, cargo, and a truck camper combined. It’s calculated as GVWR minus the truck’s curb weight, and your exact number is printed on the driver’s door jamb sticker.
Why does payload matter more than towing for truck campers?
A truck camper sits in the bed, so nearly 100% of its weight counts against payload — unlike a trailer, where only tongue weight does. A truck rated to tow 12,000 lbs might only carry 1,800 lbs of payload.
How much does water really weigh?
Fresh water weighs 8.3 lbs per gallon. A typical 20-gallon tank adds 166 lbs before you load a single sock. That’s why this calculator adds water on top of dry weight.
What happens if I exceed my payload?
Overloading strains suspension, brakes, and tires, worsens handling and stopping distance, can void your warranty, and may create legal liability in an accident. Aim to stay under 85% of rated payload for a real-world safety margin.
Estimates only. Truck payloads in our database are typical values — configurations vary. Always confirm your exact payload on the door jamb sticker and follow your vehicle and camper manufacturers’ ratings.
