Just looking at the picture, I would ask a couple of questions:
- how adjustable is the WDH? Setting them up for the correct height and tensioning of the chain is pretty important to get the weight distribution correct.
- I assume the chains have a quick release at the camper frame clamps. Undoing or screwing shackle screws every time is way too much work for me.
- the only anti-sway would be the rotational resistance of the chain connection plate under the ball. Is this designed to be anti-sway or just WDH?
I ended up with an Equal-i-zer 600/6000 which appears to be a quite a bit more adjustable. Because it uses spring bars which provide 4 point anti-sway as well as WDH, the location of the camper frame clamps is not nearly as critical, and can be moved a few inches either direction to avoid obstacles on the camper frame.
Mounting the spring bars is a simple matter of inserting them into the hitch - sprung retaining button in a slot holds them in place. Raise the tongue of the hitched camper with the tongue jack until the bars pivot into place. Insert retaining pins in the camper frame clamps, retract tongue jack and I'm good to go.
I have not tried other setups, but I am very happy with what I have. I would not want to tow my camper without it - I tested without in the dealer lot before taking delivery. Without the WDH, both camper and van "bounced" a lot even at 20-30 MPH. With WDH, the van rides normally even when hitched up. Good enough that DW feels comfortable driving the rig - was definitely NOT the case with our old Explorer and PUP (without WDH). Drives normal and no sway to 75MPH on I-25 (tested, but normally tow at 65 or less due to camper tires).
The Explorer was light in the front, which could be felt in the steering. And the rig would start to sway at 62MPH, scaring the DW on I-80 Sierra Mt downgrades.
