Understanding Toyota Highlander Towing Basics

Before you attach anything to your Highlander, you need to understand the basics of vehicle towing behind an RV. Not every car can be towed behind a motorhome. Some vehicles can be flat-towed with all four wheels on the ground. Others need a dolly or a full trailer. The method you choose depends entirely on your vehicle’s drivetrain and transmission design.

Why Drivetrain Matters for Towing

The drivetrain of your Highlander determines how power reaches the wheels. Toyota offers the Highlander in front-wheel drive and all-wheel drive configurations. Some older models came with rear-wheel drive. Each drivetrain handles towing differently. Front-wheel drive vehicles, for example, have different transmission stress when being towed compared to rear-wheel drive vehicles. All-wheel drive vehicles add even more complexity because all four wheels are connected to the drivetrain.

When you tow a vehicle with the engine off, the transmission does not receive lubrication the way it does when the engine is running. This can cause serious damage to internal components. Toyota addresses this concern in the owner’s manual for each Highlander model. Some models allow flat towing safely. Others strictly prohibit it and require a dolly or trailer to keep the transmission protected.

Transmission Considerations

The transmission type in your Highlander is another critical factor. Automatic transmissions generally have more restrictions when it comes to flat towing. The gears and internal components rely on engine-driven fluid circulation for lubrication. When the engine is off and the vehicle is being pulled, this fluid circulation stops. Manual transmissions often handle flat towing better because they do not rely on a pump for lubrication in the same way.

Toyota’s automatic transmissions in newer Highlander models are designed with specific tolerances and fluid systems. Towing these vehicles incorrectly can void the warranty and lead to expensive repairs. Always consult your owner’s manual before deciding on a towing method. When in doubt, use a dolly or trailer to eliminate any risk of transmission damage.

Can You Flat Tow a Toyota Highlander?

Flat towing means pulling the vehicle with all four wheels on the ground behind the RV. This method is popular among RV owners because it requires minimal setup and takes up no extra space. But flat towing is only safe for specific vehicles that Toyota has approved for this method.

Which Highlander Models Support Flat Towing?

The ability to flat tow a Highlander depends on the model year and drivetrain. Older rear-wheel drive Highlander models with manual transmission were generally approved for flat towing. These vehicles could be towed with all four wheels on the ground without causing drivetrain damage.

However, most modern Highlander models use all-wheel drive and automatic transmissions. Toyota does not recommend flat towing for these configurations. The all-wheel drive system connects all four wheels to the transmission and transfer case. Towing an AWD Highlander with all four wheels on the ground can cause severe damage to the transmission and transfer case components.

Here is a simple breakdown of flat towing eligibility:

• Rear-wheel drive with manual transmission: Generally approved for flat towing. Check your specific model year.
• Front-wheel drive with automatic transmission: Typically not approved for flat towing. Requires a dolly or trailer.
• All-wheel drive with automatic transmission: Not approved for flat towing. Requires a dolly or trailer.

What the Owner’s Manual Says

Your Toyota Highlander owner’s manual is the ultimate authority on towing. Every Highlander comes with a section dedicated to towing and recreational vehicle towing. This section specifies exactly which towing methods are approved for your particular model. It also outlines speed limits, distance restrictions, and any special requirements.

Do not rely on forum posts or advice from other RV owners. Towing regulations and recommendations change between model years. What worked for a 2010 Highlander may not apply to a 2023 model. Always read the manual for your specific vehicle before setting up your tow rig.

Tow Bar Setup for RV Towing

If your Highlander is approved for flat towing, you will need a proper tow bar setup. A tow bar connects the front of your Highlander to the rear of your RV. This setup allows the vehicle to follow the RV smoothly and safely on the road.

Choosing the Right Tow Bar

Not all tow bars are created equal. You need a tow bar specifically designed for the Toyota Highlander. Universal tow bars may seem convenient, but they often do not provide the secure fit and proper geometry needed for safe towing. Look for a tow bar that is vehicle-specific and rated for your Highlander’s weight.

Popular tow bar brands for the Highlander include Blue Ox, Roadmaster, and Demco. These manufacturers offer base plates that bolt directly to your Highlander’s frame. The base plate creates a solid connection point and makes attachment and detachment quick and easy. Invest in a quality tow bar and base plate. These are not areas where you want to cut corners.

Essential Accessories for Flat Towing

A tow bar alone is not enough. You need several accessories to ensure a safe and legal towing setup. Here is what you will need:

• Vehicle-specific base plate: Bolts to the Highlander’s frame for a secure tow bar connection.
• Safety cables: Provide a backup connection between the Highlander and the RV in case the tow bar fails.
• Supplemental braking system: Applies the Highlander’s brakes when the RV slows down. Required by law in most states.
• Wiring harness: Connects the Highlander’s lights to the RV’s electrical system for brake lights and turn signals.
• Towing mirrors: Extend your rearview visibility to see the Highlander and trailer clearly.

Each of these accessories plays a vital role in your towing safety. The supplemental braking system is especially important. When the RV brakes, the towed vehicle continues moving forward due to momentum. Without a supplemental brake, the Highlander pushes against the RV, causing dangerous stopping distances and potential damage.

Dolly Towing as an Alternative

If your Highlander cannot be flat-towed, dolly towing is an excellent alternative. A tow dolly lifts the front wheels of the Highlander off the ground while the rear wheels remain on the road. This method works well for front-wheel drive and all-wheel drive vehicles that cannot be flat-towed.

How Dolly Towing Works

With a tow dolly, the front of your Highlander is loaded onto the dolly and secured with straps or chains. The rear wheels roll freely on the pavement. This setup keeps the transmission lubricated because the wheels that connect to the transmission are either off the ground or rolling freely.

Dolly towing is slightly more involved than flat towing. You need to load and unload the Highlander onto the dolly at each stop. This can be inconvenient at busy campgrounds or rest areas. But the peace of mind that comes with knowing your Highlander is safely towed is well worth the extra effort.

Benefits of Dolly Towing

Dolly towing offers several advantages over flat towing for the Highlander. First, it is safe for all drivetrain configurations, including AWD and automatic transmission models. Second, it reduces wear on the transmission because the drivetrain is not under load during towing. Third, dollies are widely available for rent at RV dealerships and camping supply stores.

Some popular dolly options include the Demco Roller Falcon and the Roadmaster Dolly. These dollies feature easy-loading ramps, secure wheel straps, and built-in lighting connections. Choose a dolly with a weight capacity that exceeds your Highlander’s curb weight for a safe setup.

Legal Requirements and Safety Considerations

Towing a vehicle behind an RV is subject to state and local laws. These laws vary widely, and failing to comply can result in fines or, worse, accidents on the road. Understanding the legal requirements before you hit the highway is essential.

State Towing Laws You Need to Know

Most states require a supplemental braking system when towing a vehicle behind an RV. Some states also have speed restrictions for towed vehicles. For example, certain states limit flat-towed vehicles to 55 miles per hour, while others allow speeds up to 65 miles per hour. Your tow bar and dolly setup must comply with the laws of every state you plan to travel through.

Here are common legal requirements for RV towing:

• Supplemental brakes: Required in most states for vehicles under 3,000 pounds when towed.
• Safety cables: Required in all states as a backup connection between the towed vehicle and the RV.
• Lighting connections: The towed vehicle’s brake lights and turn signals must be connected to the RV.
• Speed limits: Some states impose lower speed limits for towed vehicles.
• Length restrictions: The combined length of the RV and towed vehicle must not exceed state limits.

Check the laws for every state on your route before you depart. A quick online search for “state towing laws” will give you the information you need. When in doubt, install a supplemental braking system and follow the most restrictive speed limit. It is always better to be safe than sorry.

Safety Tips for Towing a Highlander Behind an RV

Safety should always come first when towing. Here are some practical tips to keep in mind:

1. Inspect your setup before every trip: Check the tow bar, base plate, safety cables, and braking system for wear and proper connection.
2. Practice backing up and turning: Towing a vehicle changes the way your RV handles. Practice in an empty parking lot before your trip.
3. Monitor the Highlander during stops: Check the wheels and brakes for overheating on long drives. Towed vehicles can experience brake fade.
4. Follow the recommended towing speed: Exceeding the speed limit for towed vehicles puts extra stress on the tow bar and braking system.
5. Keep the Highlander in neutral: Always place the vehicle in neutral when towing. Never tow in park or drive.

Common Mistakes When Towing a Highlander Behind an RV

Even experienced RV owners make towing mistakes. These errors can lead to vehicle damage, legal trouble, or dangerous situations on the road. Here are the most common mistakes to avoid.

Ignoring the Owner’s Manual

This is the biggest mistake you can make. Every Highlander model has specific towing guidelines from the manufacturer. Ignoring these guidelines can void your warranty and cause costly drivetrain damage. Read the manual. Follow the manual. It is that simple.

Skipping the Supplemental Brake

Some RV owners skip the supplemental braking system to save money or avoid installation hassle. This is a dangerous and often illegal decision. Without a supplemental brake, your stopping distances increase dramatically. In an emergency, the towed Highlander will push the RV, making it nearly impossible to stop safely.

Using the Wrong Towing Method

Flat towing an AWD Highlander that Toyota does not approve for flat towing is a recipe for disaster. The transmission and transfer case can suffer catastrophic damage within miles. Always confirm your Highlander’s towing eligibility before choosing a method. When in doubt, use a dolly or trailer.

Neglecting Regular Inspections

Your towing setup takes a beating on the road. Straps loosen, cables wear, and connections can corrode. Inspect everything before each trip and during rest stops along the way. A five-minute inspection can prevent a costly breakdown or a dangerous accident.

Expert Tips for a Smooth RV Towing Experience

Towing a Highlander behind an RV becomes second nature with practice. Here are some expert tips to make your experience smooth and stress-free.

First, invest in a quality tow bar and base plate. The connection between your RV and the Highlander is the most important part of your setup. A reliable tow bar gives you confidence on the highway and prevents rattling or disconnections. Look for brands with strong warranties and positive reviews from other RV owners.

Second, plan your routes with towing in mind. Some mountain passes and steep grades put extra strain on your braking system. If you are towing through hilly terrain, allow more stopping distance and use lower gears on descents. Your RV’s engine and brakes work harder when pulling a toad, so plan accordingly.

Third, keep a maintenance log for your towing setup. Track when you replaced cables, checked brake pads, and inspected the tow bar. This log helps you stay on top of maintenance and provides valuable records if you ever need to file a warranty claim or insurance report.

Finally, enjoy the journey. Having a separate vehicle at your destination opens up a world of exploration. You can visit remote campgrounds, hike trails that require a car, and run errands without dragging your entire RV. Towing a Highlander behind your RV gives you the best of both worlds.

Conclusion

So, can I tow a Toyota Highlander behind an RV? The answer is yes, but with important conditions. Your Highlander’s drivetrain, transmission, and model year determine the safest towing method. Rear-wheel drive manual transmission models can often be flat-towed with a proper tow bar setup. AWD and automatic transmission models typically require a dolly or trailer to protect the drivetrain.

Always consult your owner’s manual before towing. Follow Toyota’s specific guidelines for your vehicle. Invest in quality accessories like a vehicle-specific tow bar, base plate, supplemental braking system, and safety cables. Respect the legal requirements in every state you travel through.
