SIZING WD AND TRAILER HITCH SYSTEMS
•Weigh loaded trailer tongue to determine proper system size.
•Choose a system with tongue rating at or above the actual trailer tongue weight.
•Tongue rating of trailer hitch must meet or exceed the measured tongue weight of the trailer. OEM hitches
may not be rigid enough for tongue weight and may need to be replaced (too much flex and won’t carry the
load).
•Total trailer gross weight rating must never exceed tow vehicle rated gross tow rating.
