Checking Loads
The best way to confirm that all
loads are within limits is to check
them at a public scale. For public
scales in your area, check your local
phone book, or contact your trailer
dealer or rental agency for
assistance.
If you cannot get to a public scale,
you can estimate the total trailer
weight by adding the weight of your
trailer (as quoted by the
manufacturer) with everything in or
on the trailer.
If you normally pull the same load
each time you tow a trailer, you can
use a suitable scale or a special
tongue load gauge to 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.
Towing Equipment and
Accessories
Towing can require a variety of
equipment, depending on the size of
your trailer, how it will be used, how
much load you are towing, and
where you tow.
Discuss your needs with your trailer
sales or rental agency, and follow the
guidelines in this section. Also make
sure that all equipment is properly
installed and maintained, and that it
meets federal, state, province, and
local regulations.
