Towing capacity & payload calculator

The same check the TowCheck app runs: is everything in your truck plus the trailer’s tongue weight inside your payload — and is the tongue weight, trailer weight and hitch rating each within its limit? Free, nothing stored.

Shopping for a trailer? See how much your truck can tow. Just need one number? Try the tongue weight calculator or the truck payload calculator.

Your truck

Door jamb certification label
Owner’s manual, spec sheet, or a scale

Your trailer

As you tow it: water, propane, gear on board
Leave blank to assume 12.5% of the loaded trailer weight

In the truck

Everyone in the cab plus everything in the bed — 0 if the truck is empty

Three numbers get you a verdict

  • ☐ Truck payload — or GVWR and curb weight
  • ☐ Loaded trailer weight
  • ☐ People and cargo riding in the truck (enter 0 if it's empty)

The app does even more

  • Scan the door-jamb sticker instead of typing the GVWR
  • Add each person, pet and piece of gear — the total keeps itself up to date
  • Save a profile per trip and re-check in seconds
  • A pre-tow checklist you tick off before every departure

TowCheck is an informational planning aid that does arithmetic on the figures you supply. It is not a certification or inspection service and does not replace a certified scale — always verify your weights before you tow.
