Section 3: Pre-Travel Information

Wire Harness/Connector Plug

A 7-way wire harness/connector plug is wired into your trailer to connect electrical power
from the tow vehicle for travel. This supplies power to the RV brakes, taillights, clearance
lights, turn signals, brake lights, etc. Wiring to operate your brakes must be the same size in
both the tow vehicle and RV (the RV brake wiring is 12-gauge wire).
When attaching wires to your tow vehicle, tape all the connections for moisture protection.

The connector plug may build up corrosion with extended use and should be cleaned
periodically to insure good electrical contact. Make sure the connector plug is kept clean
and protected from road elements as you travel.
Weighing Your Tow Vehicle & RV
When the RV is fully loaded it should be weighed. The actual weight of the vehicle, all
options, liquids, the hitch weight, and your personal cargo is important for you to know so
you do not exceed the GVWR. Two important factors when loading your RV are total weight
and balance.
It is imperative that you verify compliance within all applicable weight ratings. Overloading
your RV will void the Towable Limited Warranty and the warranties of many component
part manufacturers.
Periodically weigh your RV at a public scale to determine proper load distribution. To
obtain the side-to-side weights, there needs to be enough space on either side of the scale
to accommodate the RV being partially off the scale. Keep in mind that individual scales
will operate differently.
To weigh your tow vehicle and RV
Total weight of your tow vehicle and RV must not exceed the GCWR.
Do not assume that you can tow a RV that happens to be within the
capacity of the tow vehicle hitch. By doing so, you may exceed the total
GCWR of your tow vehicle and RV towing combination.
It is important to redistribute the load to avoid component failure as well
as to improve the handling characteristics of the vehicle and not void the
Towable Limited Warranty.
