I noted you have the same model and year of Renegade as we have. Only think I changed was adding a few towel hangers and mainly I added a rear air dump switch on the dash. I think the 2020s have but not the 2019. I forget cost but I had the parts and had it installed and total cost was about 500. Also I use a different Brake system the Air Force One which uses the air from the air brakes of the rv to feed a module which is mounted under the hood of the Dodge Ram 2015 3/4 diesel pickup which I tow. I like it much better as it applies brakes to the toad at the same amount you push on the brake in the coach. Nothing to hook up inside the toad between the seat and a reed valve mounts between the arm on the brake pedal in the toad and fire wall well up in the dash, hook air line to front bumper and you done. Hope you find this information useful.
