Flat towing a 2021 Jeep Wrangler is a popular choice for RV owners and adventure seekers. This Jeep model is designed with features that make flat towing possible, but mistakes can cause expensive damage.
If you want to bring your Wrangler on the road with you, it’s important to understand the right way to do it step by step, with all the details that matter.
What Is Flat Towing?
Flat towing, also called “dinghy towing,” means pulling your vehicle with all four wheels on the ground. The 2021 Jeep Wrangler is one of the few modern SUVs that supports this method from the factory. This is possible thanks to its transfer case design, which lets you disconnect the drivetrain from the wheels.
Why The 2021 Jeep Wrangler Is Ideal For Flat Towing
Many modern vehicles can’t be flat towed because their transmissions or drivelines can get damaged. The Wrangler, however, is built for this. According to Jeep, the 2021 Wrangler’s 4×4 system allows for safe flat towing when set up correctly. This makes it a favorite for RV enthusiasts who want to explore off the beaten path.
Essential Equipment For Flat Towing
To flat tow your 2021 Wrangler, you’ll need more than just the Jeep and an RV. Here’s what you need:
- Tow bar: Connects the Wrangler to your RV.
- Base plate kit: Attaches to the Jeep frame to provide secure mounting points.
- Safety cables: Backup connection in case the tow bar fails.
- Tow bar wiring kit: Connects your Jeep’s lights to the RV for legal signaling.
- Supplemental braking system: Required in most states, helps stop the Jeep when you brake the RV.
- Drop/rise hitch adapter (if needed): Keeps the tow bar level.
A common mistake is skipping the supplemental braking system. Not only is this illegal in many areas, but it also puts extra strain on your RV brakes.
Step-by-step Guide: How To Flat Tow A 2021 Jeep Wrangler
Setting up your Wrangler for flat towing isn’t difficult, but every step matters. Here’s how to do it:
1. Prepare The Jeep
- Park on a level surface.
- Turn off all accessories and set the parking brake.
- Ensure the Wrangler is in park (automatic) or neutral (manual transmission).
2. Transfer Case Settings
- Start the engine, press the brake pedal.
- Shift the transmission into neutral.
- While holding the brake, shift the transfer case lever to neutral (N).
- Confirm the “N” indicator lights up on your dash. This step is critical—if the transfer case isn’t in neutral, you can destroy the transmission.
3. Transmission Settings
- For automatic: After the transfer case is in neutral, shift the transmission to park.
- For manual: Leave the transmission in gear (typically first or reverse).
4. Attach The Tow Bar And Cables
- Install the base plate kit if you haven’t already.
- Connect the tow bar to the base plates.
- Attach safety cables in a criss-cross pattern under the tow bar.
- Connect the wiring kit for brake and turn signals.
- Hook up the supplemental brake system.
5. Final Checks
- Double-check all connections.
- Make sure the steering wheel is unlocked so the front wheels can turn freely.
- Release the parking brake.
Missing the steering wheel unlock is a common error. If the wheels can’t turn, you’ll damage your tires and steering system.
6. Test Everything
- Walk around the Jeep and RV.
- Test all lights and brakes.
- Check for any warning lights on the dash.
