We can get your 2021 Jeep Grand Cherokee set up to flat tow, and I'll make a list for you of all the parts that you'll need, which will include base plates, a tow bar, wiring, and a supplemental braking system. The exact parts for your '21 Grand Cherokee will be the following:
- Base Plate Kit: Demco Tabless Base Plate Kit # DM9519291
- Tow Bar: Demco Dominator Non-Binding Tow Bar # DM9511008
- Wiring Kit: Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Wire to 6-Wire # RM-152-98146-7
- Supplemental Braking System: Demco SBS Stay-IN-Play DUO Supplemental Braking System # DM86VR
OR
- For a motorhome with air brakes: Demco SBS Air Force One Supplemental Braking System # DM26VR
The Demco Tabless Base Plates ensure your 2021 Grand Cherokee keeps a streamlined look after the base plates are installed. The Dominator tow bar is the best option because it has long arms which make it easier than other tow bars to maneuver when towing, and has integrated safety cables and an adjustable tilting head so a high-low adapter won't be needed. Having these features on a tow bar means you won't have to purchase them separately to help save with some expenses.
The Flexo-Coil wiring kit is designed to prevent any type of electrical feedback to keep your Jeep's electrical system safe, and both the Stay-IN-Play DUO and Air Force One are highly recommended because they are one-time installs which will never require any type of removal or reactivation, and because they give you braking proportional to that of your motorhome. This results in much smoother braking than most systems which send out a pre-set amount of braking power and are far more rigid.
The only other thing I recommend, in order to keep your Grand Cherokee safe from rocks and debris while it is being towed behind your motorhome, is to add the Sentry Deflector for Demco Tow Bars # DM9523135.
I have added links below to a number of video reviews for you to check out as well.
