Tongue weight

Tongue weight is 10–15% of the loaded trailer weight, and it counts against your payload, not your towing capacity. That is the trap: a truck can be well inside its tow rating and still be overloaded, because 1,000 lb of tongue weight landed on the rear axle.

Addition of trailer hitch weight cannot cause vehicle weights to exceed Rear Gross Axle Weight Rating (RGAWR) or Gross Vehicle Weight Rating (GVWR). These ratings can be found on the certification label located on the driver door or doorframe.

Tongue weight is a LOADING outcome, not a published vehicle spec — it depends on how YOU load the trailer, which is why manufacturers publish a percentage rule instead of a table. Too little causes sway; too much overloads the rear axle.

Common questions

How do I calculate tongue weight?

Tongue weight is 10–15% of the loaded trailer weight for a travel trailer (7–12% is often quoted for boat and utility trailers). A 7,000 lb trailer should carry roughly 700–1,050 lb on the ball.

Why doesn't the manufacturer publish tongue weight?

Because it is not a property of the trailer — it is a property of how you loaded it. Move a generator from the back of the trailer to the front and the tongue weight changes by a hundred pounds. No manufacturer can publish a number for that, which is why every one of them states the percentage rule instead of a table.

Does tongue weight count against payload or towing capacity?

Payload. It sits on your hitch, which sits behind your rear axle, so it counts against your Gross Vehicle Weight Rating and Rear Gross Axle Weight Rating — not against your tow rating. This is the single most common way people overload a truck that is 'within' its towing capacity.

Measure it rather than guess

A tongue weight scale is the only way to know where you actually are in the 10–15% band.
