Any trailer over 1000-1200 lbs should be towed with trailer brakes, which means either a controller or surge brakes must be present. And I am not a fan of surge brakes. Sometimes we simply must stop quickly to avoid an accident. I have towed a few thousand miles without brakes... never again. Also, if the trailer ever starts an oscillating sway, the proper way to respond is to engage trailer brakes only; you can't do that without a controller.
With that combo a wd hitch might not be necessary, but may still be desirable to level the rig and restore some weight to the steering axle. Sway control adds safety, again not entirely necessary as long as 10-15% of trailer weight is on the hitch, but for peace of mind to an inexperienced tower with a family to protect, it is a good idea. Some wd hitches contain sway control... Andersen No-Sway, Equal-I-Zer, etc. Friction sway bars work and are affordable, but not quite as effective especially when they get wet in rain.
