my understanding.. any trailer over 6,000 pounds total weight .. needs a WDH.
for truck hitch and frame.. prevents the jacking at the receiver .. over bumps and uneven roads...
Maybe for a certain brand/model of truck, but it is not an overall requirement.
Many receivers are rated for 1,500lbs+ of tongue weight and 15,000lbs+ of trailer weight, withOUT a WDH. And, 1500lbs in the back of a heavy duty pickup is barely enough to make it squat.
When you get up into the world of heavy duty pickup trucks with properly-rated receivers, WDH becomes optional based on personal preference and personal experience. WDH can not only improve handling, but it can also improve the ride, reduce the "push-pull" feeling you get from large vehicles passing by, and with the right hitch, prevent sway.
