TowCheck: Towing Calculator

Already towing? Get a clear go/no-go on every weight limit. Still shopping? See what your truck can really tow. Both count your people, pets and gear. Free.

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 CAN MY TRUCK TOW?

Still shopping for the trailer? Enter just your truck and TowCheck flips the question around: the tongue weight to stay under, and the loaded trailer weight that usually means, in plain words — a small travel trailer, a mid-size boat, a car hauler. Your passengers, pets, and gear are already counted, so it's your number, not the brochure's. Add your truck's tow rating and TowCheck caps the answer with it, and always tells you which limit is doing the work.

WHAT IT CHECKS • Truck payload • Truck GVWR • Trailer GVWR • Tongue weight percentage (the 10 to 15 percent window) • Hitch receiver rating • Tow rating, when you're sizing up a trailer

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 • Answers both questions: is this rig safe, and what could this truck tow • 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
