Parts to Flat Tow 2021 Jeep Wrangler


I’m in need of a flat tow setup for my ‘21 Jeep Wrangler RV toad. What’s the most economical package, to include the baseplate, tow bar, brake system, and lighting/signal?


Expert Reply:

The base plate kit can vary depending on the Jeep front bumper type. I am quoting parts based on the factory plastic bumper. If you have a factory steel bumper, Off road bumper with 3/4" D-rings or Off road bumper with 1" D-rings, just let me know so I can adjust the recommendation if necessary.

For the base plate kit I would recommend the etrailer # e98948 Invisible Base Plate Kit with removable arms. I have attached a installation video for a 2020 Wrangler Unlimited to give you an idea of what is needed.

Next you will need a tow bar. You will want the Roadmaster # RM-520 Tow bar with cross bar. For a bit more you can upgrade to the Roadmaster # RM-522 All-Terrain Non-Binding tow bar. A non-binding tow bar will let you easily disconnect your tow bar even if your coach and towed vehicle is not on level ground or at a difficult angle.

When your coach and towed vehicle are hitched together on level ground, the tow bar should be within 3” of level, otherwise you will need to add a High-Low Adapter I have attached an article explaining how to measure for an adapter, and a link to a page showing all of our adapters.

You will also need safety cables to keep the towed vehicle connected to your coach in case of a tow bar failure. I would recommend the Roadmaster # RM-645 which are 64” long and rated for 8000 pounds. I like that the connectors are made so they can not bounce off the cable hooks. I also prefer the straight cables compared to coiled – it just looks cleaner when they are all tucked away. If you find that your clevis hooks will not fit through the ears on the back of your coach you will need to add Roadmaster # RM-910022 cable connectors rated for 6000 pounds.

Next you will need a tow bar wiring kit. I recommend the Roadmaster # RM-152-98146-7 Universal wiring kit which includes everything you need to connect your RV's tail, brake, and turn signal lights to your towed car. Diodes prevent feedback and wire your car to operate as a combined system. Includes a 7-way to 6-way straight adapter cord.

Your Jeep weighs in about 4500 pounds so you will need a supplemental braking system installed in it. This will improve braking and handling, and extend the life of your coaches braking system. Additionally, most states require supplemental braking if your towed vehicle is over 3000 pounds. If your coach has traditional hydraulic brakes then I recommend the Brake Buddy # HM39524 portable system that has proportional braking and has a wireless display for your cab so you can see your braking system status or change profiles from your driver's seat. You can save a bit of money going with the Brake Buddy # HM39494 which is a basic system.

If your coach has air brakes, then instead of the Brake Buddy system, you will need the Demco # DM26VR supplemental braking system for air brakes.

I have attached an article below about supplemental braking systems.

Finally, you should double check your vehicles owner's manual to determine if your specific model vehicle can be flat towed and any special requirements in regard to fuses, equipment, and any additional service that may be required.
