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 weighing station,
building supply company, trucking company, junk yard, etc.
