Recommended Flat Towing Equipment For A 2021 Grand Cherokee L

Question:

My RV has air brakes. The brake system you recommended has hydraulic brakes. Will it still work or do I need something like the Air Force One?

To flat tow your 2021 Jeep Grand Cherokee L you'll need a tow bar, base plate, braking system, tow bar wiring kit, and safety cables. I have the following recommendations for you below:

Tow Bar: etrailer SD Non-Binding Tow Bar for Roadmaster Direct-Connect Base Plates # e74ZR. This tow bar is specifically designed to fit Roadmaster direct-connect base plates. It features non-binding latches and telescoping, self supporting arms that make connecting and disconnecting your Jeep on any terrain a breeze. It has an adjustable head that tilts up or down 3" and the shank has a built-in 1-1/2" rise or drop to keep tow bar parallel with road while towing without the use of a high/low hitch adapter. It also comes with safety cables included.

Base Plate: For an Overland model you'll need the Roadmaster Direct-Connect Base Plate Kit # RM77ZR and for a Summit model you'll need the Roadmaster Direct-Connect Base Plate Kit # RM59ZR. Both of these kits have direct-connect style attachment points for fast and easy hookup and disconnect. They both have removable arms for a clean factory look when not in use.

Tow Bar Wiring Kit: Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. This diode kit allows you to use your Jeep Wrangler Unlimited's tail lights and wiring system while preventing feedback from your RV.

Note: Product intended for models with 3.6L engine. See your local dealer for wiring harness information if your vehicle needs MOPAR RV towing wiring harness kit #82216418AA.

Braking System: Roadmaster BrakeMaster Braking System with BrakeAway for RVs with Hydraulic Brakes # RM-9060. This truly proportional braking system connects directly to your 2022 Newmar Kountry Star's hydraulic brakes and applies the brakes in your towed car using the same force that you apply to the brakes in your RV.

It will require the Roadmaster BrakeMaster Custom Fit Seat Adapter # RM49ZR and Roadmaster Universal Stop Light Switch Kit # RM-751000 to properly fit you Jeep and alert you when the brakes are being applied in your Jeep.

Safety Cables: Since the # e74ZR already has safety cables included you won't need to purchase any separately.

Since your 2022 Newmar Kountry Star has air brakes you will want an air brake compatible system like the Demco Air Force One Supplemental Braking System w/ Wireless Coachlink # DM26VR instead. This system is a one time installation that uses the air pressure from your RV's brakes to apply the brakes in your towed car in the same manner. The low-profile box installs out of the way and is always at the ready, so no setup is required. The included wireless braking monitor will alert you when the brakes are being applied in your 2021 Jeep Grand Cherokee L or in the event of a breakaway.
