To displace the same amount of weight, the Andersen would place no more strain on the coupler than a more traditional WDH. It's all leverage, whether that leverage is created by chain tension or by bars. The direction may be different, but leverage should be similar. As for the wear on the chain guides, that is due to either using the wrong kit for the frame size, or installing the guides so they are not lined up properly. We have had zero issues with our Andersen hitch over 3 1/2 years.

The only issue I saw with the Andersen that affected multiple customers was the braking material protruding from the socket that holds the ball. They apparently redesigned that to correct it, because ours has not had the problem.

A coupler is designed to take high vertical force (tongue weight), continual moderate horizontal force pulling the ball back, and occasional force in the other horizontal directions.
A conventional WD system greatly increases the vertical force on the coupler and ball, but the Andersen applies horizontal force, pushing the coupler against the back of the ball.

Because the effect of the WD is due to applying torque (about the lateral axis) to the coupler, the same load transfer effect means the same torque, regardless of WD system design. I agree that the shank is being used as a lever inserted into the receiver, and so to the receiver and tow vehicle it doesn't matter what hardware is used to pry on the lever.

On the other hand, because the lever arm of the Andersen is short (the height from ball centre to chain plate) compared to the lever arm of a traditional WD system (the length of the spring bar), the chain force is much higher... there's a reason that the Andersen No-Sway's chain is so thick! The other issue is that while the conventional WD pulls down on the trailer frame and in reaction pushes up on the coupler, the Andersen pulls forward on the trailer frame and in reaction pushes back on the coupler. That's higher forces, and horizontal instead of vertical.

I can see that Brian. But do you think it would cause a coupler to fail? Ours works like it's brand new.

EDIT: I should have said it did work like it was brand new, until I had it cut off and replaced with a Collar-Lok coupler for ease of hooking/unhooking.

It depends on the coupler. The only moving part in most couplers is some sort of jaw at the bottom in the back, which is only intended to keep the coupler from pulling up off of the ball. Pushing against it with hundreds of pounds, all of the time, works out for most of them (which is either good design or sheer luck), but some can't take it.

The Bulldog Collar-Lok should be very tolerant of this use (or abuse).

The less expensive alternative that Escape was offering in 2014. I believe this is it:
Pro Series - Weight Distributing Kit - Round Bar

Escape set it up for me.

Yep, that's what we had with the 17B and mistakenly thought that since the Andersen cost more(2X+ Pro Series) it had to be better. Went back to Pro Series- installed easily myself and is far easier to set up and the ball is 2-3" further back which lets us open the tailgate.

Just in case anyone was confused about these models... a Grand Cherokee isn't just a bigger Cherokee - the only things that these two very different models have in common are Jeep badges and "Cherokee" (a traditional Jeep brand) in their names.

Historically, I think Cherokee was born first, I have a 1991 Cherokee Sport I'm restoring and the original owner.It has a 6 cyl straight six and a 3500# capacity. It was a great marketing ploy in 1992 when Chrysler came out with the Grand Cherokee model, to create a demand for and compete with the Cherokee, both within one company. Previously there was the Jeep Wagoneer which ended I think around 1991.

I bought a used Cherokee Chief. Shortly after I got it, the full-time 4x4 crapped out and cost me $1,200 for repair ( a lot of money at the time ). The dealer had had the vehicle painted in order to sell, and tiny bubbles formed all over it.
Oh, and the first gas shortage arrived in North America. The V8 got about 6-8 miles per gallon.
