Coupler Maintenance Guide

One of the most essential parts of travel trailer

ownership is following a routine maintenance

schedule. Because our trailers are built to last,

a routine maintenance will help ensure your

trailer is safe on the road for years to come. Your

maintenance schedule should be scheduled around

an annual schedule and your travel plans.

This guide can ensure your coupler stays in good

shape. Though this guide covers the essentials

of coupler maintenance, be sure to use your best

judgment about maintaining your trailer and visit a

mechanic regularly to keep things in tip-top shape.

COUPLER MAINTENANCE

Make sure pieces are not damaged, bent, or

functioning improperly. On occasion, you may need

to tighten or replace different coupler components to

make sure you can tow safely.

We have more information about replacing the

threaded nut on page 2.

You can replace the locking plate by unscrewing

the threaded nut (see page 2 for instructions) and

inserting the locking plate in place. Make sure the

angled pieces are facing down. You can see the

angeled pieces of the locking plate in the image to

the right.

THREADED NUT MAINTENANCE In addition to the routine maintenance that should be done to your coupler and hitch, this guide outlines how to best replace the threaded nut underneath your coupler to promote safe towing conditions. CHECKING THE NUT It’s important to check your threaded nut, or locknut, on a routine basis but at least once a year or before long trips. You want to ensure that the threaded nut is secure, not damaged, and tight enough.
