Your correct, the "Equal-i-zer" brand WDH has integrated sway control thus doesn't require the separate friction sway control arm.
The Eaz-Lift WDH requires the separate friction sway control arm. Also, if the TT is longer then 25ft most standard WDH manufactures recommend an additional friction sway control arm on the opposite side.
WDH's with integrated sway control (Equal-i-zer, Reese Strait-Line, etc.) will provide enhanced TV handling should a sway event arise.
