Sorry Marshall -- not picking, but bells go off with this statement. Let me clarify some terminology. We are speaking about after-market items that are not part of the OEM trailer A-frame or hitch and they are not inherent in a tow vehicle's receiver. WD & antisway are incorporated into the combined mechanism of many brands; eg, Reese Dual Cam, Equal-I-Zer has their own system, Hensley Arrow though expensive is the very best, Blue Ox, and many lesser "house brands" at dealers and so on...
Weight Distribution (WD) gear: Spring bars that when activated will apply torque to the tow vehicle (TV) frame so that not all the hitch weight is carried by the rear TV axle; ie, some of the hitch weight is actually transferred to the front axle. With passenger and other TV cargo, hitch weight might otherwise put a rear axle over its rated load rating. Measure to the top of all four TV wheel well enclosures before hitching. After hitching and engaging the WD gear the same 4 reference points should all settle by approximately the same amount.
Antisway: A variety of methods. First -- friction antisway is seen less commonly with new equipment and can be unreliable when you need it most -- in wet weather. Antisway works to dampen swing of the trailer if the tow vehicle makes a sudden lateral move. It helps keep the trailer in line with the tow vehicle and is not usually called on during 99% or more of routine towing. It is an invaluable aid for the inevitable, but it buys only a margin of safety and will not prevent loss of control in extreme maneuvers.
Now take a look at Don in E Texas
' avatar pic. Some tow vehicles naturally don't need weight distribution. I can make a blanket statement that the greatest majority of us will always want to utilize WD & antisway gear. I have seen my antisway function in a situation where the trailer would not have been put in harms way. I definitely want antisway providing a margin of safety for stronger emergency avoidance and braking situations.
