Rusty and Texas Diesel, I have had the Jordan Research Ultima 2020 trailer brake controller on my Ram for over two years now. They have since updated the internal portion of the unit and made a few inprovements to the actuating cable assembly. You are correct, it has THE MOST ACCURATE proportioning of ANY trailer brake controller on the market because of the trick actuating system.
Recently, I had an internal problem with my Ultima 2020 and talked with Jordan Research about this. Even though I believe it was out of warranty they sent me out a brand new (complete) Ultima 2020! Apparently they were upgrading any of the earlier units with the latest version to those experiencing problems. I guess I could safely add Jordan Research to my list of outstanding vendors!
The Ultima 2020 has a real high quality black anodized aluminum case that requires no mounting bracket (you screw directly through the case in the holes provided). In addition, there is a large red LED readout and a green LED continuity light, and of course, a manual gain button. Also noteworthy is the unit does not have to be mounted directly on centerline with the brake pedal and can me mounted at any angle (no pendulum).
What I like best about the unit is (after it's setup properly), you don't even know the trailer is behind you..... no tell tale bumps from the trailer until the pendulum kicks in (i. e. , lag) or strange stopping characteristics associated with some electronic (only) type controllers.
The Tekonsha controllers are very popular and very reliable... I just thought I would add another choice and an explanation for a little known controller.
