I called around to several shops in Colorado Springs and was unable to find anyone with direct experience with the 2017 Expy and after-market controller. One guy had done a 2018 and said that all the warning lights came on and he had to reset them with an ODBII scanner, which didn't give me a lot of confidence. So I called the dealer service dept, the same one that diagnosed the OEM controller as "faulty", and he said there shouldn't be a problem.
So I ordered the Prodigy 2 from e-trailer, with the specific adapter, and got it working in about an hour. Every time the truck starts it displays a warning about the brake module, but just press OK and it goes away. All I had to do was pull the OEM unit out of the dash and unplug it from the connector. Then plug the Prodigy into that connector. Since I wanted to have some good visibility of the device, I mounted it on the lower left dash just above the parking brake lever. I did that with the driver door open and centered it on that panel, but found that the door hit it when closing. So I had to drill new holes and move it to the right. The vehicle-specific wiring adapter is plenty long to reach that block behind the OEM device.
I've tested it with one trailer and it worked like a champ. I'm calling it a success!
