We can definitely help and get your 2021 Jeep Grand Cherokee Trailhawk outfitted with a complete flat tow set up. I'll go ahead and list out every part you need to make it easy to order:

- Base Plate Kit: Roadmaster Direct-Connect Base Plate Kit # RM-521440-5

- Tow Bar: Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar # RM-676

- Wiring Kit - Jeep WITHOUT ParkSense: Roadmaster Universal Hy-Power Diode Wiring Kit # RM-152
OR
- Wiring Kit - Jeep WITH ParkSense: Roadmaster Wiring Kit with Smart Diodes # RM47ZR

- Supplemental Braking System: Demco SBS Stay-IN-Play DUO Supplemental Braking System # DM86VR

- Towed Vehicle Battery Charge Wire Kit for Demco Supplemental Braking Systems # DM66VR

The Roadmaster Direct-Connect Base Plates are great because they have removable tabs which means your Jeep is going to maintain its clean aesthetic when you aren't flat towing it. The Nighthawk is easily the best tow bar you can get because of its aluminum body which makes it lighter and easier to handle than other tow bars, and long 52" reach which allows your Jeep to track behind your motorhome better than bars with shorter arms.

The Nighthawk even includes both safety cables and an electrical cord so you don't have to buy those separately. The diode wiring kit will prevent any type of electrical feedback to keep your Jeep's electrical system safe, and you'll connect it to the cord that comes with the Nighthawk. Just make sure you get the right kit, depending on if you have the optional ParkSense proximity sensor feature on your Grand Cherokee.

As for the braking system, the Stay-IN-Play DUO is easily the best because it gives you braking proportional to that of your motorhome. So when you hit the brakes on your motorhome, your Jeep is going to get the same amount of braking power, resulting in much smoother braking than other systems. The battery charge line will keep your battery charged at all times, even on long journeys.

Finally, to protect your Grand Cherokee from rocks and other debris hitting it while you are flat towing, I recommend considering a rock guard, the Roadmaster Tow Defender Protective Screening # RM-4750.
