Towing confidence, calculated
Get a clear 0–100 towing safety score—and see exactly which limit is tightest before you hitch up.
Excellent Match
Your setup is within the entered limits.
Scoring Engine v1
Use the ratings on your vehicle door label, owner’s manual, hitch, trailer tag, and—when possible—certified scale tickets.
Transparent by design
The 100 points reward safety margin and preparation. They never average away a manufacturer-limit violation.
Loaded trailer versus maximum tow rating.
People, cargo, hitch hardware, and tongue weight.
Hitch rating plus trailer-type tongue ratio.
Estimated combined vehicle and trailer weight.
Brakes, controller, ratings, chains, and tires.
Terrain and weather reduce the available margin.
Verify before you hitch
The Defender + Chaparral demo begins with an 8,200 lb tow rating and the Chaparral’s published 3,500 lb dry boat weight, then adds illustrative trailer, fuel, gear, and passenger weight. Those assumptions are not a substitute for your exact vehicle label, trailer tag, equipment ratings, or scale weights.
Tow Genius is a planning and education tool, not a certification that a combination is legal or safe. Follow the most restrictive applicable vehicle, hitch, trailer, tire, and local-law limit.
