HOW TO USE THIS TOOL

Compare Tow Vehicles: what the result means

Use before buying a tow vehicle to expose payload differences hidden by advertised tow ratings.

Steps

  1. Enter one realistic loaded trailer.
  2. Add shared people, cargo and hitch assumptions.
  3. Enter vehicle-specific payload and tow ratings.
  4. Compare margins rather than headline maximums.

Formula

Payload margin = payload rating − occupants/cargo − hitch − estimated tongue weight.

Important limits

  • Use ratings for the exact configuration or physical vehicle label.
  • This comparison does not choose a vehicle for you.
