Flat towing a 2021 Jeep Wrangler is a popular way for RV owners and adventurers to bring their vehicle along without using a trailer. The Wrangler is known for its “flat tow” compatibility, but doing it right takes more than just hooking up and driving off. Here’s a clear, practical guide for safely flat towing your 2021 Wrangler, so you avoid mistakes and enjoy a smooth journey.
Why Flat Tow A 2021 Jeep Wrangler?
The 2021 Jeep Wrangler stands out among vehicles because it is designed to handle flat towing (also called “dinghy towing”) with ease. Unlike many cars, you don’t need to disconnect the driveshaft or install complicated aftermarket parts. This makes the Wrangler a top choice for people who travel by motorhome and want a capable SUV when they reach their destination.
What You Need Before You Start
Before you flat tow, gather these essentials:
- Tow bar rated for your Wrangler’s weight
- Base plate kit for secure attachment
- Safety cables for extra security
- Tow braking system (often required by law)
- Wiring harness for brake and signal lights
Always check that all equipment is compatible with the 2021 Wrangler and is installed according to manufacturer instructions.
Preparing Your Jeep For Flat Towing
Improper setup is a common beginner mistake. Follow these steps to avoid damage:
- Place the transfer case in Neutral (N). This disconnects the wheels from the drivetrain.
- Put the transmission in Park (for automatic) or in gear (for manual).
- Turn the ignition to the ACC position. This unlocks the steering wheel but does not power the engine.
- Release the parking brake.
Important: Never tow with the transfer case in 2H, 4H, or 4L. Doing so can ruin your transmission.
Quick Reference: Transfer Case & Transmission Setup
| Component | Correct Position | What It Does |
|---|---|---|
| Transfer Case | Neutral (N) | Disconnects drivetrain |
| Transmission (Auto) | Park (P) | Prevents rolling |
| Transmission (Manual) | Any gear | Prevents rolling |
Attaching Your Wrangler To The Tow Vehicle
- Connect the base plate: Attach the tow bar to the base plate on your Wrangler according to the instructions.
- Attach safety cables: Cross them under the tow bar and connect to both vehicles.
- Plug in wiring harness: This syncs your Jeep’s lights with your RV or tow vehicle.
- Install supplemental braking: Place the braking system inside the Jeep as needed.
Pro tip: Crossing safety cables under the tow bar creates a cradle. If the tow bar disconnects, the cables can catch it and prevent the bar from digging into the road.
Testing Before You Tow
Testing prevents problems on the road. Here’s what to check:
- Ensure all connections are tight and secure.
- Test that your Jeep’s brake lights and turn signals work with the tow vehicle.
- Double-check the transfer case and transmission are in the correct positions.
- Make sure the steering wheel is unlocked (important for cornering).
A quick walk-around before leaving can catch issues that could cause costly damage or accidents.
Driving Tips And Safety
Flat towing feels different from normal driving. Your Wrangler will track behind your RV or tow vehicle, but you must still drive carefully.
- Accelerate and brake slowly to reduce stress on the tow bar and cables.
- Allow extra stopping distance. Even with a braking system, it takes longer to stop.
- Avoid sharp turns and U-turns, which can stress towing components.
- Check all connections at every stop.
Keep in mind, the 2021 Jeep Wrangler weighs between 4,000 and 4,500 lbs. Make sure your RV or tow vehicle is rated for this weight.
Common Mistakes To Avoid
New flat towers often make these errors:
- Leaving the transfer case in the wrong position: This can destroy your transmission.
- Forgetting to unlock the steering wheel: This leads to tire wear or even damage to the steering system.
- Not using a braking system: Many states require it, and it’s safer for you and others.
- Skipping safety cables: These are your last line of defense if the tow bar fails.
Cost Comparison: Flat Towing Vs. Trailer
Is flat towing cheaper? Here’s a quick look at average costs:
| Item | Flat Towing | Trailer |
|---|---|---|
| Initial Equipment | $1,500 – $2,500 | $2,000 – $5,000 |
| Storage/Space | Minimal | Requires large space |
| Setup Time | 10-15 minutes | 20-30 minutes |
| Fuel Economy | Better | Worse (more drag) |
Non-obvious Insights For Beginners
- The battery may drain if the ignition is left in ACC for long trips. Consider a battery disconnect switch or check at stops.
- Some states require additional reflectors or breakaway systems. Check local laws before you travel.
- After long towing, shift the transfer case out of Neutral and drive your Jeep a few miles. This helps lubricate the transmission.
Wrapping Up
