My grandson just gave me pictures of his 1988 Comanche with 12" lift 35 x 12.5 tires and this does have a 125 lb Exact Center, he drives 85mph on the interstate and says it drives like an SUV. He is 26 so keep that in mind. He says it is very good and it was very very bad before the installation of EC. The EC used was an early prototype and not the current single shaft tandem.
For those who want more mounts here is maybe 50 pictures, some were tests some may have been changed, some might have not been used so this is for ideas and options. EC Pics - Google Drive
Is that a stock JL stabilizer now. If it is the ends should work with EC. Roadmaster will make sure you are happy in the end. They do have a limited life time guarantee on everything they sell. They probably have 50000 products so that is saying a lot.

Yes. For me, I don’t care about the steering stability, that’s just icing. For me, it’s all about being able to back up while towing if I need to.
Backing up IS possible John. Straight line and slowly with Comms between the drivers and it’s just fine.
So, I was under the impression that this setup would eliminate the need for a spotter. The situation I am thinking of is the need to do a U-Turn on a road that is almost but not quite wide enough, forcing me to do a three- point turn.
Don’t see how that’s possible. To back up, in a 3-point turn, the wheels of the TOAD would to do a lot of (counter)steering changes as well as lock in place.
Go watch the video at post #9. At 1:09, it shows a Class B pulling a Jeep, backing a Jeep on a curve with the wheels turned.
Ok, I watched it. It definiitely seems to hold the Jeep's wheels at center, or close to it. That's one of the points I was making; the steering wheel has to be locked so the wheels don't caster.
Here is a letter from a local fire chief explaining how his staff liked the Exact Center prototype we installed on the village Ford 5500 HD 4WD rescue ambulance. He waited for his workers to notice the improvement from the Exact Center addition. I drove this Ambulance after the install, it was like a big SUV.Here is a thread from JL Wrangler that might be helpful

The most modified is my son's 98 TJ 4" long arm lift but only 33's and a V-8. That has been a test mule for a lot of offroad and highways. He does 80 in that thing and drives with no hands. Before we started it was hard to keep in a lane, the wind would also blow him all over the road now it is rock solid and he has a 75 lb unit and he says it is just right. My grand son has a Comachee with a lift and 35's. He says it drives real good actually better than my 2018 JL Rubicon when it was stock. We also had a 2015 JKU Rubicon that was stock. We have done a lot of RVs and HD trucks. A friend who is a fire chief had a new Ambulance Rescue truck on a Ford 4500 4WD. It had a short wheelbase and had a lot of weight behind the rear axle. It was very hard to drive over 50 mph uncontrollable. We put a prototype 220 lb unit on it and it turned into a big SUV. I test drove after and it was as good as any truck/RV I have ever driven. I have a new 2021 RV a Dynamax Isatta 5 28ss explorer 4WD on a Ram 5500 chassis at 20000 lbs. It was not terrible but not near as good as I wanted. The center was soft and hard to keep now with a 220 lb unit it drives like a Suv. You would not feel the change any pressure
I would think you would be very happy with any pressure 80 to 110 lbs. We put 90 lbs on a 2015 JKU Rubicon, I drove it 250 miles and thought it was great, the owner, my son's wife thought it too heavy feeling so we changed to solid rod ends and told her we lower the pressure. She liked what she thought was lower pressure but did not like the very fast sports car-like feeling. We then changed it to 75 lbs with poly bushings and this made her very happy. We did not tell her it was lower pressure, she just thought we changed the ends. Our RV unit has an on-the-fly trim feature. That makes install final centering a 2 second button push and lets an RVer trim the center to have the EC push against side winds etc. We did not think Jeepers would want that attribute. However, I have an idea I thought you (heavy mods, big tires, big lifts) might find interesting. I am an inventor so I would be interested in getting some users to test new ideas. This one would allow you to have full EC ability when you want, a trim feature(allows center change), and the ability to lockout part first 1"-2" of tie rod movement or all tie rod movement, it would just be as it is with no stabilizer if 100% locked out. We have a patented lock that will hold 600 lbs. We would give you a toggle-like lever to flip to shut off the centering part. This ability is not a product yet.
Fox and Falcon have their adjustment because you can really feel the changes and they need them. I suspect you want it adjustable because at 3 it is very stiff. This is different. We can give you the control you need with a very good solid center and a wheel you can turn with one finger. Watch the drive video of the 2015 JKU driven with one finger, which was a 90 lb spring. We need some users to report how they like the 75 lb and then give them 100 lbs to see what they think. I do not think even at 120 lbs on a big lift, big tire wrangler will be able to be driven with one finger. If we do not tell people there is an "X" pressure push back few would notice anything. The second day you drive your rig after an EC install I think you will not notice the pressure, it will not be anything you notice as heavy. This is not even close to the resistance a Falcon or Fox creates. My 2021 Bronco Outerbanks 2.7 has a much stiffer wheel than any level of assistance we have done on EC. My wife's 2020 Lincoln Aviator has very heavy steering too. Must be a Ford thing. I do not think you will want the Falcon adjustment, this is just a solid center and a solid hold at center yet still easy to turn. We have many videos, if you search there are several on Wrangler JL. More pressure will help people who do Toad backing as it fights additional weight the front tires out on the ground making them want to turn.
I need RM to get to their pressure change in house (near complete) so we can try a few things.
Maybe this new steering stabilizer will minimize the need for constant corrections, thus a JL with a small dead spot will be less noticeable since you won't have to correct as often.
You need to try a base unit EC and see how you like it.
Yes, I already ordered it on Dec 30. Waiting for it to arrive.
Would really appreciate a performance report after install.
