Whoa guys, the main purposes of the WD bars is to shift weight from the rear axle of the TV towards the front axle, and I would think that means transferring any overloaded weights on the rear axle that causes it to sag forward, including weight in the bed of the pickup. Make sense?
a second consideration could be when the rear axle hits a bump, that upward force on the hitch and WD bars could temporarily exceed the normal weighted pressure on those bars??
We have the Reese SC hitch, which is very similar to the Equalizer except the L Bracket that the WD bars rest on has brake pads that Reese claims has more friction (and makes less noise) than the metal to metal friction of the equalizer. In any event, we have had zero sway in our set-up below.
