WHAT MATTERS

Built around the complete towing picture

TowGauge separates vehicle identity, manufacturer ratings, vehicle-specific labels and equipment fitment rather than treating them as one data source.

Coupler type

Start with the actual trailer coupler or king-pin system.

Installed vs stored

Some locks secure a connected trailer; others protect an unattended trailer.

Weather resistance

Outdoor exposure makes corrosion resistance and key design important.
