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.
