How to Use This Calculator
- Enter your vehicle GVWR and subtract passenger weight and in-vehicle cargo weight.
- Enter the trailer weight (loaded GVWR or scale weight at a truck stop).
- Set the tongue weight percentage (typically 10-15% of trailer weight for travel trailers).
- Review available towing capacity, tongue weight, and safety margin.
- Never tow a trailer that exceeds your vehicle's rated capacity -- exceeding limits risks brake and structural failure.
