Weight distribution hitch needed?

While it may not be 'required' you'll find the towing experience much better with a WDH. It will handle better. You will want anti-sway. Greatly helps when towing in wind and when semi's pass. If you go with the Equalizer brand WDH hitch it includes built in anti-sway. These types of WDH's do not require any separate anti-sway devices which often must be disconnected when backing.
