Can I tow it?
Published towing capacity answers one question out of four. This works out all of them at once — towing capacity, payload, GCWR and the hitch itself — and tells you which one you actually hit first.
Can I tow it?
Four limits decide the answer, and you are bound by the tightest. Most trucks run out of payload long before they run out of towing capacity.
Not the dry weight on the brochure — add water, gear and propane.
A receiver hitch under the bumper. 10–15% of trailer weight lands on the ball.

Estimated — GCWR only
Payload is the limit you hit first — 1,515 lb of 1,700 lb used, leaving 185 lb. Tongue weight plus passengers, cargo and hitch hardware — everything the truck itself carries.
Safe band for this hitch is 700–1,050 lb (10–15%). Within the recommended band for this hitch type.
Payload defaults to a realistic mid-trim figure rather than the brochure maximum, which belongs to a stripped work truck. Replace it with the number on your yellow door-jamb sticker for a real answer. Curb weight is an estimate unless you change it and only affects the GCWR row.
The four limits, and why the famous one rarely matters
Every truck carries four separate ceilings when it tows, and you have to be under all of them simultaneously. Manufacturers advertise the second one, forums argue about the second one, and the second one is almost never the one that stops you.
- Payload — everything the truck carries: passengers, cargo, the hitch hardware, and the trailer's tongue weight. Printed on the yellow label in your door jamb.
- Towing capacity — the loaded trailer on its own. The headline number.
- GCWR — truck and trailer added together. Constrains you on long grades and in the heat more than anything else.
- Hitch rating — the receiver has its own class rating. A Class III hitch stops at 8,000 lb no matter what the truck is capable of.
The reason payload usually wins is arithmetic rather than opinion. A conventional trailer needs 10–15% of its weight on the ball to track straight. At 15%, a 10,000 lb trailer is 1,500 lb sitting on your hitch — and that comes out of a payload budget that is often only 1,500 to 1,900 lb on a well-equipped half-ton, before a single passenger.
Getting honest numbers in
Two inputs decide whether the answer means anything. Use the payload from your door-jamb sticker rather than the brochure figure, because the brochure number belongs to a two-wheel-drive regular cab with vinyl seats. And use the trailer's loaded weight, or its GVWR if you have not scaled it — dry weight leaves out water, propane and everything you own.
If you want certainty rather than arithmetic, a CAT scale at a truck stop costs a few dollars and gives you axle-by-axle weights for the whole rig. Nothing on this page beats a scale ticket.
Common questions
Why does my truck run out of payload before towing capacity?
Because tongue weight counts against payload, not against towing capacity. A conventional trailer puts 10–15% of its weight on the ball, so a 9,000 lb trailer lands about 1,100 lb on the truck before anyone gets in. Add four people and a cooler and a half-ton with 1,700 lb of payload is done — while still using barely two-thirds of a 14,000 lb tow rating.
What is the difference between GVWR, GCWR and towing capacity?
GVWR is the maximum the truck alone may weigh, fully loaded. GCWR is the maximum for the truck and trailer together. Towing capacity is the trailer on its own. They are three separate ceilings and you must be under all of them at once — which is why this calculator shows all four limits rather than one number.
Does a weight-distributing hitch increase how much I can tow?
It does not add payload or raise your GCWR. What it does is move some of the tongue load off the rear axle and back onto the front axle and the trailer, so the truck sits level, steers properly and brakes evenly. Many manufacturers require one above a certain trailer weight in order to grant the full tow rating, so it can unlock a higher published number — but the arithmetic on this page is unchanged.
Where do I find my truck’s real payload?
The yellow sticker inside the driver’s door jamb, which reads "The combined weight of occupants and cargo should never exceed X lbs". That figure is specific to your truck as built, options and all. The brochure maximum belongs to a stripped work-truck configuration and is often several hundred pounds higher than yours.
Should I use dry weight or loaded weight for the trailer?
Loaded, always. Dry weight excludes water, propane, batteries, and everything you pack. A travel trailer with a 6,800 lb dry weight routinely crosses 8,500 lb loaded. If you have not weighed it, use the trailer’s GVWR — that is the honest worst case and it is printed on the trailer.

This is arithmetic, not authorisation. The certification label on your vehicle and your owner's manual are the authority for what it may tow and carry. Overloading a truck or trailer is dangerous and in most states illegal. When it is close, weigh it.
