"Sway bars should not be used to compensate for poor hitch set up. "
I X2 that statement.
Recommend getting scale weights after you are loaded for a trip.
If your tongue weight is sufficient and the trailer is level or slightly nose low and WD setup properly you should not have a sway problem provided all weights are within the TV and trailer capacity.
Make sure tires are also within their weight capacity.
After all this I would recommend sway control which is integral with many WD systems.
I want sway control for those times you may have to dodge a deer, dog, or someone who has cut you off. Also for a large Motor-home that passes you going 20 mph faster than you.
