I've got a Prodigy in my 99 CTD. I've towed a friend of mine's Jeep (trailered around 9,000 lbs. ) twice across country.
My Dad & brother both have Prodigy controllers in their pickups. Dad's tows a 28' dually tandem gooseneck hauling cherries in the summer.
All 3 rigs have no issues at all with the Prodigy, it works well. Even with the semi-wet load behind Dad's rig, it's been a very effective controller.
In a recent model truck, a Prodigy should be a 5 minute install. 2 screws to mount the bracket, plug the controller in. Done.
Technically, the Jordan should be a superior controller as it it does measure pedal travel rather than using an inertial sensor. I can see how that'd be desirable under slick conditions. I can't speak to installation, though. From what I've seen and read, getting the cable rigged to the pedal can be a sensitive operation. If you can do that, and do some simple wire matching to the trailering pigtail, it shouldn't be a bad installation.
Frankly, if you're only towing 5k, I'd go Prodigy and not look back. UNLESS... ... you tow on slick surfaces and have had problems sliding.
