● A recommended tongue weight varies in accordance with the types

of trailers or towing as described below.

● To ensure the recommended values shown below, the trailer must

be loaded by referring to the following instructions.

• Tongue Weight

The gross trailer weight should be distributed so that the tongue
weight is 9% to 11%. 
(Tongue weight /Gross trailer weight x 100 = 9% to 11%)

Gross trailer weight

Tongue weight

If using a weight distributing hitch when towing, return the front
axle to the same weight as before the trailer connection.

If front axle weight cannot be measured directly, measure the
front fender height above the front axle before connection. Adjust
weight distributing hitch torque until front fender is returned to the
same height as before connection.

The gross trailer weight, gross axle weight and tongue weight
can be measured with platform scales found at a highway weigh-
ing station, building supply company, trucking company, junk
yard, etc.
