Tongue Weight Calculator for Travel Trailer Payload
A tongue weight calculator is useful only when that number is also counted against truck payload and receiver tongue rating.
Tongue weight counts against payload because that weight is carried by the truck.
TowMargin adds estimated tongue weight to passengers, cab and bed cargo, hitch hardware, and accessories when estimating used payload.
Use a measured tongue weight from a tongue scale or certified scale when you have one. Otherwise, use an estimate based on loaded trailer weight and an editable tongue weight percentage.
A 6,500 lb loaded travel trailer at 13% tongue weight adds about 845 lb to the truck before driver, passengers, gear, and hitch hardware are added.
Decision chain: loaded trailer weight creates the tongue weight estimate, tongue weight uses truck payload, and the same tongue weight must also fit the receiver tongue rating.
That is why TowMargin shows payload remaining, receiver tongue margin, loaded trailer weight, and the limiting factor in the same report.
Recheck payload rating, receiver tongue rating, loaded trailer weight, and scale readings before relying on a close result.
