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.
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
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
Free — with an optional $2.99 one-time Pro upgrade.
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.
