The tongue weight of a trailer should be what percentage of the gross trailer weight?

The tongue weight of a trailer should typically be between 10% to 15% of the gross trailer weight. This ensures proper weight distribution and stability while towing, helping to prevent swaying and improving control. For example, if a trailer weighs 3,000 pounds, the tongue weight should ideally be between 300 to 450 pounds. Proper tongue weight is crucial for safe towing and vehicle handling.
