To achieve a proper tongue load,
start by loading 60 % of the load
toward the front of the trailer and
40 % toward the rear, then re-adjust
the load as needed.

Towing a Trailer
Checking Loads
The best way to confirm that vehicle
and trailer weights are within limits
is to have them checked at a public
scale.
Using a suitable scale or a special
tongue load gauge, check the tongue
load the first time you set up a
towing combination (a fully-loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.
