Travel Trailer Tongue Weight Percentage Calculator

A travel trailer tongue weight calculator starts with loaded trailer weight and a percentage estimate, then shows how much of that weight moves into truck payload.

Tongue weight percentage estimates how much of the loaded trailer weight is carried by the truck at the hitch.

For travel trailers, 10-15% of loaded trailer weight is a common starting range when no measured tongue weight is available.

TowMargin defaults to 13% for travel trailer estimates, and the field is editable when you have a better number.

Edit 13% if a tongue scale, CAT scale comparison, or manufacturer loading note gives you a better tongue-weight estimate for the loaded trailer.

On a 6,800 lb loaded trailer, 12% tongue weight is about 816 lb. At 14%, the estimate is about 952 lb.

That 136 lb difference can decide whether payload or receiver tongue margin is close.

Decision chain: the percentage turns loaded trailer weight into estimated tongue weight, then TowMargin applies that tongue weight to payload and receiver tongue checks.

Changing tongue weight percentage affects used payload, payload remaining, receiver tongue margin, and GVWR checks when actual truck weight is entered.
