How To Flat Tow Jeep Wrangler : Dinghy Towing Setup Instructions

Flat towing a Jeep Wrangler requires a transfer case in neutral and a properly connected tow bar system. If you own a Wrangler and plan to take it on an RV trip, knowing how to flat tow Jeep Wrangler models safely is essential to avoid transmission damage and ensure legal compliance on the road.

Flat towing, also known as dinghy towing, means pulling your Jeep behind a motorhome with all four wheels on the ground. It saves you from needing a trailer and makes setup quick once you learn the steps. This guide covers everything from pre-tow checks to disconnecting at your campsite.

How To Flat Tow Jeep Wrangler

Before you hook up, understand that not every Wrangler can be flat towed without modifications. The process varies slightly depending on your model year and transmission type. Manual transmissions are simpler, while automatics require specific steps to prevent pump damage.

Check Your Jeep Wrangler Compatibility

Most Jeep Wranglers from 1997 onward are flat towable, but you must verify your specific year and trim. The key factor is the transfer case. You need a two-speed transfer case with a neutral position. Models like the Rubicon, Sahara, and Sport typically have this.

  • 1997-2006 TJ models: Flat towable with manual or automatic transmission
  • 2007-2018 JK models: Flat towable with manual or automatic transmission
  • 2018-present JL models: Flat towable with manual or automatic transmission, but check the owners manual for specific procedures
  • 4xe hybrid models: Require additional steps for battery disconnection

If your Wrangler has a one-speed transfer case, like some older base models, flat towing is not recommended. Always consult your owners manual before attempting to tow.

Gather The Required Equipment

You need more than just a tow bar. The right equipment makes the process safe and legal. Here is a checklist of essential items:

  • Tow bar rated for your Jeeps weight (Class III or IV recommended)
  • Base plate mounted to your Wranglers frame
  • Safety cables or chains crossing under the tow bar
  • Lighting kit with taillights, turn signals, and brake lights
  • Supplemental braking system (required in most states for vehicles over 3,000 lbs)
  • Breakaway switch that activates brakes if the towed vehicle detaches
  • Tow bar wiring harness compatible with your Jeep
  • Key for the steering column lock (if applicable)

Do not skip the supplemental braking system. Many states enforce this law, and it prevents your motorhome from pushing the Jeep during sudden stops.

Prepare Your Jeep Wrangler For Flat Towing

Preparation involves mechanical adjustments and electrical connections. Follow these steps in order to avoid mistakes.

Step 1: Set The Transfer Case To Neutral

This is the most critical step. With the engine running, shift the transmission to neutral. Then move the transfer case lever to N. You will feel it click into place. Some JL models have a push-button transfer case, so follow the on-screen prompts.

After setting the transfer case to neutral, turn the engine off. Leave the key in the ignition or use a steering wheel lock bypass kit to prevent the wheel from locking.

Step 2: Disconnect The Battery (For Some Models)

On certain JL Wranglers and 4xe hybrids, you must disconnect the negative battery terminal to prevent electrical drain. This step is not needed for most TJ and JK models. Check your owners manual to confirm.

Step 3: Install The Base Plate And Tow Bar

If you have a permanent base plate installed, simply attach the tow bar arms to the mounting tabs. If not, follow the manufacturers instructions for bolting the base plate to the frame. Torque all bolts to spec.

Connect the tow bar to the base plate, then attach the safety cables. Cross them under the tow bar to catch the Jeep if the main connection fails. Plug in the wiring harness for the lights.

Step 4: Test The Lights And Brakes

Turn on your motorhomes headlights and taillights. Walk to the back of the Jeep and confirm all lights function properly. Test the turn signals and brake lights. If something is dim or not working, check the wiring connections.

Activate the supplemental braking system according to its manual. Most systems use a brake pedal pusher or a proportional controller. Test it by driving slowly and applying the motorhomes brakes.

Flat Towing Procedure: Step By Step

Once everything is connected, you are ready to tow. Follow this procedure every time you hit the road.

  1. Start the motorhome engine and let it idle.
  2. Shift the motorhome transmission into drive or low gear.
  3. Slowly pull forward to take the slack out of the tow bar.
  4. Stop and check all connections again. Ensure the tow bar is locked.
  5. Drive at low speed for the first mile to confirm everything feels right.
  6. Monitor the Jeep in your rearview camera or mirrors. Look for sway or bouncing.
  7. Keep your speed under 65 mph (55 mph is safer for long trips).
  8. Avoid sharp turns. Make wide arcs to prevent the Jeep from hitting curbs.

If you hear unusual noises or feel resistance, pull over immediately. Check the transfer case position and tow bar connections.

Common Mistakes When Flat Towing A Jeep Wrangler

Even experienced towers make errors. Avoid these pitfalls to protect your Jeep and your safety.

  • Forgetting to put the transfer case in neutral. This can destroy the transmission within miles.
  • Leaving the steering wheel unlocked. The wheels can turn and cause the Jeep to drift.
  • Using undersized tow bars or safety cables. Always exceed the weight rating.
  • Skipping the breakaway switch. It is a legal requirement in most areas.
  • Not checking tire pressure. Underinflated tires can overheat and fail.

Another common mistake is assuming all Wranglers are the same. The 4xe model requires additional steps, such as disconnecting the high-voltage battery. Always read the supplement manual for your specific year.

How To Disconnect And Drive Your Jeep After Towing

When you reach your destination, reversing the setup is straightforward. Do not skip these steps.

  1. Park the motorhome on level ground and engage the parking brake.
  2. Disconnect the wiring harness and safety cables.
  3. Remove the tow bar from the base plate. Store it securely.
  4. Get in the Jeep and turn the ignition to the run position (do not start yet).
  5. Shift the transmission to neutral.
  6. Move the transfer case from N to 2H or 4H. You may need to rock the Jeep slightly to engage the gears.
  7. Start the engine and let it idle for a minute to circulate fluid.
  8. Test the steering and brakes before driving.

If the transfer case feels stuck, try shifting into 4L first, then back to 2H. This often frees the linkage.

Supplemental Braking Systems Explained

You cannot rely solely on your motorhomes brakes to stop a 4,000-pound Jeep. Supplemental braking systems apply the Jeeps brakes when you brake the motorhome. Here are the main types:

  • Air brake systems: Use compressed air from the motorhome. Expensive but reliable.
  • Hydraulic systems: Use a pump to apply brake pressure. Common for heavy RVs.
  • Portable brake controllers: Sit on the floor and push the brake pedal. Easy to install.
  • Permanent systems: Mount under the dashboard and connect directly to the brake pedal.

Choose a system that matches your budget and towing frequency. For occasional towing, a portable unit works fine. For full-time RVers, a permanent system is worth the investment.

Legal Requirements For Flat Towing A Jeep

Laws vary by state, but most require the following:

  • Tow bar must be rated for the weight of the Jeep
  • Safety cables or chains must be used
  • Taillights, brake lights, and turn signals must work on the Jeep
  • Supplemental braking system for vehicles over 3,000 lbs (check your state limit)
  • Breakaway switch that activates brakes if the Jeep detaches

Some states also require a separate license plate on the towed vehicle if it blocks the motorhomes plate. Carry a copy of your owners manual showing the flat towing procedure in case you are pulled over.

Maintenance Tips For Flat Towing Your Wrangler

Frequent towing adds wear to your Jeep. Perform these checks regularly:

  • Inspect the base plate bolts for looseness. Torque them every 5,000 miles.
  • Lubricate the tow bar pivot points and ball mount.
  • Check tire tread and pressure before each trip. Rotate tires every 6,000 miles.
  • Flush the transfer case fluid every 30,000 miles if you tow often.
  • Test the supplemental braking system monthly.

Also, keep an eye on the steering components. Towing with the wheels straight can stress the tie rods and ball joints. Have them inspected annually.
