Hey Paul, congratulations on the new truck and motorhome! I can definitely help you out here. In addition to the tow bar and brake system you will need the base plate kit and your tow bar wiring. For a complete setup I recommend the following:

-Demco Tabless Base Plate Kit # DM29FR

-Demco Dominator Non-Binding Tow Bar # DM9511008 (includes safety cables)

-Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles # RM-15267

-Roadmaster Hy-Power Diodes (Qty 2) # RM-792 (extra diodes required on 2024 and newer models)

-Roadmaster Battery Disconnect for Towed Vehicle w/ Flat Tow Brake System - Gas Only # RM-766

OR

-Roadmaster Battery Disconnect for Towed Vehicle w/ Flat Tow Brake System - Diesel # RM93MR

-Towed Vehicle Battery Charge Line Kit for Demco Air Force One Braking Systems # DM66VR

Is your 2026 Renegade Super C built on the Freightliner chassis? That seems to be the most common. Assuming it is, you need the Demco Air Force One Flat Tow Brake System for 2021 and Newer Freightliner Chassis RVs w/ BrakeSync # DM23MV. If it is built on something else let me know so we can get you the right version of the Air Force One.

The rest of the parts listed above will be everything you need to flat tow your Denali. The correct battery disconnect depends on whether you have the gas or diesel model. Since the Dominator has a built-in rise/drop you probably don't need a high-low adapter. However, I would still measure to make sure you're +/- 3" of level just to be sure.

Where are you headed once you get everything set up?
