Place the trailer on a scale with axles only on the scale (see 2). If the weight
on the axles exceeds the axle system Axle Weight Rating (GAWR), then
some of the personal cargo must be redistributed forward in order to place
some of this weight on the tongue.
The tongue weight should be in between 10% - 15% of the trailer’s total
weight, but must not exceed the manufacturer’s maximum recommended
hitch weight of the tow vehicle or hitch. To determine tongue load, unhitch
tow vehicle and place the tongue hitch post on a scale. The trailer must be
properly loaded as determined above, with your allowable personal cargo
and variable weights.
Use a scale, such
as a bathroom
scale, that has a
lower weight limit
than your tongue
load to check the
tongue weight by
using the following
method (see illus-
tration).
Place a piece of wood of approximately the same thickness as the bathroom
scales on the ground in line with the trailer hitch jack as shown. It should be
so spaced that a short piece of pipe or other round piece will lay exactly one
foot from the centerline of the jack extension. Place the scales so that another
round piece can be exactly two feet from the centerline of the jack extension in
the other direction. Place a 4 x 4 on the two round pieces and screw the jack
extension down on the top of the 4 x 4 until the tongue of the trailer is sup-
ported by it. Multiply the scale reading by three. This will be the tongue weight
of your trailer. If you exceed the capacity of the bathroom scales, increase the
two-foot dimension to three or four more feet, but always multiply the scale
reading by the total number of feet between the wood and scales.
Note: Be sure trailer is level when you read scales.
