Understanding the Best Way to Tow a Car Behind an RV: Your Options Explained

When it comes to the best way to tow a car behind an RV, there isn’t a one-size-fits-all answer. Your choice depends heavily on your RV type, the vehicle you intend to tow, your budget, and personal preference. Each method offers distinct advantages and disadvantages.

Let’s explore the primary methods for towing a vehicle behind your home-on-wheels.

Why Tow a Car Behind Your RV?

Having a separate vehicle at your destination offers incredible flexibility and convenience.

  • Local Exploration: Easily drive into towns, national parks, or trailheads without unhooking your entire RV.
  • Errand Running: Simple trips to the grocery store or fuel station become much easier.
  • Maneuverability: A smaller car is far more nimble for navigating tight spots or crowded areas.
  • Emergency Transport: In unforeseen circumstances, a separate vehicle can be invaluable.

Weighing Your Options: A Quick Overview

Before diving deep, here’s a snapshot of the three main methods for towing a car behind an RV:

  • Flat Towing (Four-Down): All four wheels of the towed vehicle are on the ground.
  • Tow Dolly: The front two wheels of the towed vehicle are on a small trailer, while the rear two wheels are on the ground.
  • Car Hauler Trailer: All four wheels of the towed vehicle are on a full-sized trailer.

Each option has specific requirements and implications for your vehicle and RV setup.

Flat Towing (Four-Down): The Popular Choice for Many RVers

Flat towing, also known as “four-down towing,” is often considered the most convenient method once set up. Your towed vehicle travels directly behind your RV with all four of its wheels on the ground, just as if it were being driven. This method minimizes the hassle of loading and unloading.

It’s a popular choice for those seeking a streamlined towing experience, offering many benefits for regular travelers.

Pros and Cons of Flat Towing

Understanding the upsides and downsides helps determine if this is the best way to tow a car behind an RV for you.

Pros:

  • Simplicity: No need to store or maneuver a dolly or trailer at your campsite.
  • Ease of Connection: Once the base plate is installed, connecting and disconnecting is relatively quick.
  • Less Maintenance: No extra tires or wheel bearings to maintain, unlike a dolly or trailer.
  • Better Fuel Economy (Marginal): Generally lighter than towing a trailer.

Cons:

  • Vehicle Compatibility: Not all vehicles can be flat towed. Many automatic transmissions and some manual transmissions are not suitable.
  • Upfront Cost: Initial setup can be expensive due to specialized equipment.
  • Wear and Tear: The towed vehicle’s tires, suspension, and driveline accumulate mileage.
  • No Backing Up: You cannot back up your RV with a flat-towed vehicle attached without risking damage.

Essential Flat Towing Gear

A complete flat towing setup requires several key components:

  • Base Plate: Custom-designed brackets that attach to the frame of your towed vehicle, providing connection points for the tow bar.
  • Tow Bar: The primary connection between your RV and the base plate, typically telescoping for easy hookup.
  • Safety Cables: Two independent cables that act as a backup connection in case the tow bar fails.
  • Supplemental Braking System: Required in most states and highly recommended everywhere. This system applies the towed car’s brakes in conjunction with the RV’s brakes. Options include surge, proportional, and fully integrated systems.
  • Wiring Harness/Lights: Connects the RV’s taillights, turn signals, and brake lights to the towed vehicle’s lights for safety and legality.

Vehicles Suitable for Flat Towing

Compatibility is the single biggest factor for flat towing. Always consult your vehicle’s owner’s manual to confirm if it can be flat towed “four-down.” Look for sections on “recreational towing” or “dinghy towing.”

Commonly flat-towable vehicles include:

  • Jeep Wranglers (manual and some automatic versions)
  • Certain Honda CR-Vs (older models)
  • Specific Chevrolet models (e.g., Equinox, Sonic)
  • Many manual transmission vehicles (though still confirm with manufacturer)

Never assume a vehicle is flat-towable without verifying with the manufacturer’s manual or a qualified RV towing specialist. Incorrect flat towing can cause severe transmission damage.

Tow Dolly: A Versatile Solution for Front-Wheel Drive Vehicles

A tow dolly lifts the front two wheels of your towed vehicle off the ground, while the rear two wheels remain on the road. This method is particularly popular for front-wheel drive (FWD) cars, as it protects the transmission from wear and tear.

  • Cost-Effective: Generally less expensive upfront than a full flat-tow setup or a car hauler trailer.
  • Protects Transmission: Keeps the towed vehicle’s drive wheels off the ground, preventing mileage accumulation on the drivetrain.
  • No Backing Up: While challenging, it’s generally possible to back up a very short distance with a dolly, unlike flat towing.

Cons:

  • Storage: Requires storage space at your campsite or home when not in use.
  • Loading/Unloading: Involves more effort to load and secure the vehicle onto the dolly.
  • Maintenance: The dolly itself has tires, bearings, and lights that require maintenance.
  • Maneuverability: Adds an extra pivot point, making turns wider and potentially more challenging to back up.
  • Supplemental Braking: Still requires a supplemental braking system, often integrated into the dolly itself or a separate unit.

What You Need for Dolly Towing

Beyond the dolly itself, ensure you have these components:

  • Tow Dolly: Choose a dolly with brakes (surge or electric) for safety and compliance.
  • Wheel Straps: Securely fasten your vehicle’s front wheels to the dolly.
  • Safety Chains: Connect the towed vehicle to the dolly as a backup.
  • Lights: Ensure the dolly has functioning brake lights, turn signals, and running lights, connected to your RV.
  • Supplemental Braking (if not integrated): A separate unit that works with your RV.

Best Use Cases for a Tow Dolly

A tow dolly shines in specific situations:

  • When your primary tow vehicle is FWD and not approved for flat towing.
  • If you plan to switch towed vehicles frequently, as dollys are often more universal.
  • For budget-conscious RVers looking for a reliable towing solution without the higher initial investment of flat towing or a full trailer.

Some rear-wheel drive (RWD) and all-wheel drive (AWD) vehicles can be dolly towed if the drive wheels are on the ground and the transmission can be disengaged or the driveshaft removed. Always verify with your vehicle’s manufacturer.

Car Hauler Trailer: Maximum Protection for Any Vehicle

A car hauler trailer, also known as an enclosed or open trailer, carries your entire towed vehicle with all four wheels off the ground. This method provides the ultimate protection for your vehicle, as it incurs no mileage or wear and tear during transit.

It’s often the best way to tow a car behind an RV for luxury vehicles, classic cars, or those not suitable for other methods.

Advantages and Disadvantages of Trailer Towing

While offering maximum protection, car hauler trailers come with their own set of considerations.

Pros:

  • Universal Compatibility: Can tow virtually any vehicle, regardless of its drivetrain or transmission.
  • No Wear and Tear: The towed vehicle accumulates no mileage, preserving its condition.
  • Storage Space: Enclosed trailers offer additional secure storage for gear, bikes, or other items.
  • Backing Up: Allows for easier backing up compared to flat towing (though still requires practice).

Trailer Towing Equipment Checklist

To safely tow a car hauler, you’ll need:

  • Car Hauler Trailer: Open or enclosed, ensure it has a sufficient Gross Vehicle Weight Rating (GVWR) and working brakes.
  • Tie-Down Straps: Heavy-duty straps to secure the vehicle to the trailer deck.
  • Wheel Chocks: To prevent the vehicle from rolling during loading and securing.
  • Trailer Hitch & Ball: Properly rated for the trailer’s weight.
  • Weight Distribution Hitch (Optional but Recommended): Can improve stability for heavier trailers.
  • Brake Controller: Essential for trailers with electric brakes, allowing you to control the trailer’s braking from the RV.

When to Choose a Car Hauler

A car hauler trailer is the ideal choice for:

  • Towing vehicles that cannot be flat-towed or dolly-towed (e.g., many AWD/RWD cars, luxury vehicles).
  • Protecting a valuable or classic car from road debris and wear.
  • RVers who need extra storage space in an enclosed trailer.
  • Those prioritizing the absolute preservation of their towed vehicle.

Key Considerations Before You Tow: Safety, Weight, and Compatibility

Regardless of the method you choose for the best way to tow a car behind an RV, several critical factors must be addressed before you ever hit the road. Overlooking these can lead to dangerous situations, legal issues, and costly damage.

Prioritizing safety and proper setup is non-negotiable for a successful towing experience.

Towing Capacity: Don’t Overload!

This is arguably the most important factor. Every RV has a maximum towing capacity, which is the maximum weight it can safely pull. You must know your RV’s Gross Combined Weight Rating (GCWR), Gross Vehicle Weight Rating (GVWR), and tongue weight capacity.

  • GCWR: The maximum allowable weight of the fully loaded RV and the fully loaded towed vehicle/trailer combined.
  • GVWR: The maximum allowable weight of the fully loaded RV itself.
  • Tongue Weight: The downward force exerted by the trailer’s coupler onto the RV’s hitch ball. For flat towing, this is negligible. For dollys and trailers, it’s critical.

Weigh your RV fully loaded for travel, and then weigh your towed vehicle. Never exceed your RV’s stated towing capacities. Overloading can damage your RV’s engine, transmission, brakes, and suspension, and significantly compromise safety.
