TowCheck: Towing Calculator

Free to download. Know if your truck-and-trailer setup is within every weight limit—payload, GVWR, tongue weight—before you pull out of the driveway.

Most tow calculators only weigh the trailer. That's why they tell you you're fine when your truck is 300 lb over.

TowCheck counts the whole load: trailer tongue weight, passengers, dogs, propane, fresh water, and everything in the bed. In seconds you get one color-coded verdict on whether your real, loaded setup is legal and safe.

HOW IT WORKS

Enter your truck and trailer once, straight off the door-jamb and tongue placards. Check off who and what's coming. Get an instant verdict: clear, caution, or over the limit, with a breakdown showing exactly which number is close or exceeded.

WHAT IT CHECKS • Truck payload • Truck GVWR • Trailer GVWR • Tongue weight percentage (the 10 to 15 percent window) • Hitch receiver rating

The verdict updates live as you check people, pets, and gear in and out, so you can see what to leave behind to get back under your limits.

WHY TOWCHECK • Counts the whole load, not just the trailer • Works fully offline, on device. No account, no sign-up • Save trip profiles (lake weekend, horse show, job site) and switch loadouts in a tap • Pre-tow checklist for your walkaround: hitch, safety chains, tire pressure, lights, doors, jacks • Private by design. Your vehicle and trip data never leave your phone

Free forever: the full weight calculator, trip profiles, and pre-tow checklist.

TOWCHECK PRO (one-time $2.99) • Weight Estimator: photograph gear, a person, or a pet for an instant weight estimate • Rating-Label Scanner: scan a GVWR straight off a truck or trailer sticker instead of typing it

Built for RV, boat, and horse-trailer owners, contractors, and weekend haulers.

TowCheck is a planning aid, not a substitute for a certified scale. Always follow your vehicle and hitch manufacturer's ratings.
