How to Tow a Car Behind an RV
Discover how to safely tow a car behind your RV. From choosing the right towing method and equipment to legal rules and safety tips, this guide helps make your RV travel smoother, safer, and more convenient.
Towing a vehicle behind your RV or motorhome adds a whole new level of convenience and freedom to your adventures. Once your motorhome is parked, having a smaller car makes it easy to grab groceries, explore scenic side roads, or navigate areas where a large RV simply won’t fit.
But towing isn’t as simple as attaching a hitch and hitting the road. To tow safely and confidently, you need to plan ahead. That means checking your motorhome’s towing capacity, choosing the right towing method, and installing the proper gear, from tow bars and safety cables to a secure, high-quality baseplate.
This guide walks you through everything you need to know; the benefits, the different towing methods, and essential safety tips, so you can hit the road prepared and make the most of your RV travel.
Why Tow a Car Behind an RV?
Many RV and motorhome owners quickly realize that a towed vehicle provides freedom that an RV alone cannot. Driving a 40-foot motorhome into a crowded city or through narrow campground roads isn’t practical, and that’s where towing comes in.
A compact SUV or jeep towed behind motorhome setups offers the flexibility to explore nearby attractions or handle daily errands without moving your entire rig.
Benefits of Bringing a Towed Vehicle
Bringing a towed vehicle on your trip offers convenience, flexibility, and added peace of mind during your travels.
- A towed car allows you to visit grocery stores, trailheads, and attractions without breaking down your RV setup at the campground or giving up a hard-to-find overnight RV parking spot.
- Smaller vehicles, like jeeps or sedans, are easier to maneuver and park than large RVs.
- Having a car available provides peace of mind in case your RV experiences mechanical problems during long trips.
- You can tow your car behind using different setups, from flat towing to a car hauler, depending on what vehicles can be flat towed and what equipment you own.
When Towing Makes Sense for RV Travel
Towing is especially practical on extended road trips, snowbird migrations, or vacations where you’ll be moving between multiple destinations.
It also makes sense for travelers who spend long stretches in one location but want a reliable way to explore without moving their motorhome.
In short, if you plan to camp in one place for days or weeks at a time, towing your car behind during RV travel adds a layer of convenience and mobility that’s hard to beat.
Towing Methods for RV Owners
RV owners have three main ways to tow a car: flat towing, using a tow dolly, or a car trailer. Each method has its own benefits and fits different vehicles and towing needs.
Flat Towing (Four-Down Towing)
Flat towing, often called four-down towing, means towing a vehicle with all four wheels on the ground. It’s one of the most popular setups because of its simplicity and quick hookup process. Many jeeps and certain SUVs are designed for this method, which is why they are common sights behind motorhome setups at campgrounds.
Advantages:
- Easiest and fastest to connect and disconnect.
- No need for bulky equipment or extra storage.
- Keeps campground parking simple.
- Lightweight compared to trailers.
Disadvantages:
- Only certain vehicles (often manual or select automatics) are approved for flat towing.
- May require installation of a baseplate, tow bar, and safety cables.
- Possible need for transmission modifications (lubrication pump or driveshaft disconnect).
- Exposes the car to all road debris and weather.
Tow Dolly (Front-Wheel Lift)
A tow dolly lifts the front wheels of the vehicle off the ground, leaving the rear wheels rolling. This method works well for many front-wheel drive cars that aren’t approved for flat towing. It’s a reliable way to safely tow when flat towing isn’t an option.
Advantages:
- Allows towing of most front-wheel drive vehicles.
- No need for expensive vehicle modifications.
- Generally easier on transmissions than flat towing.
- Equipment is widely available for rent or purchase.
Disadvantages:
- Dolly requires storage space when not in use.
- Slightly more complicated to load and secure.
- Reduced maneuverability in tight spaces.
- Rear wheels and undercarriage still exposed to road debris.
Car Trailer (Open or Enclosed)
A full car trailer or car hauler carries the entire vehicle, keeping all four wheels off the road. This is the most versatile solution, since it allows you to tow any make or model, regardless of drivetrain or towing restrictions. An enclosed trailer also shields the car from road debris and weather during transit.
Advantages:
- Suitable for any make or model, including those not approved for flat towing.
- Enclosed trailers provide full protection from weather and road debris.
- No wear and tear on towed car’s tires or drivetrain.
- Ideal for classic or luxury vehicles.
Disadvantages:
- Heaviest and most expensive towing setup.
- Requires substantial towing capacity from your RV.
- Takes up significant storage and parking space.
- Takes longer to load, unload, and secure the vehicle.
| Towing Method | Vehicle Compatibility | Equipment Requirements | Protection During Transit |
| Flat Towing | Limited to vehicles approved for flat towing (e.g., many jeeps) | Tow bar, baseplate, safety cables | No protection from weather |
| Tow Dolly | Most front-wheel drive vehicles; some all-wheel drive | Tow dolly, straps, safety chains | Front wheels lifted; rear exposed |
| Car Trailer | Any vehicle that fits the trailer | Car hauler, tie-downs, safety chains | Full protection if enclosed |
The best towing method depends on what you drive, your motorhome’s weight capacity, and how you prefer to tow on long trips. Some travelers prioritize ease and speed at the campground, while others value flexibility and protection, so always confirm vehicle-specific towing approvals and safety guidelines.
How to Choose the Right Towing Setup
To have a safe and smooth trip, picking the right towing setup is key. It should match your RV’s details. The setup you choose depends on your RV’s class, towing capacity, and the vehicle you plan to tow.
RV Class and Towing Capacity Requirements
Every motorhome comes with a manufacturer-listed towing capacity, which is non-negotiable when deciding how to tow your car behind. This figure is based on the RV’s gross combination weight rating (GCWR), engine size, transmission, and braking ability.
Exceeding it is not just unsafe, it can void warranties and cause serious damage to both vehicles.
Typical ranges look like this:
| RV Class | Typical Towing Capacity |
| Class A | 5,000 – 10,000 lbs |
| Class C | 3,000 – 6,000 lbs |
| Class B | 1,500 – 3,500 lbs |
For example, many Class A motorhomes can safely tow larger SUVs or even a jeep, while a smaller Class B camper van may be limited to lightweight compact cars or motorcycles. Always verify your RV’s owner’s manual before deciding whether vehicles can be flat towed or if you’ll need to use a tow dolly or car hauler.
Tow Bars, Base Plates, and Braking Systems
Once you know what your motorhome can handle, the next step is selecting the right towing equipment. The three essentials are a tow bar, a baseplate, and a supplemental braking system.
- Tow bars link your RV to the towed vehicle. They come in rigid-arm designs or modern self-aligning styles, which make hookup faster at a campground or roadside.
- Baseplates are installed on the towed vehicle’s frame and act as the anchor point for the tow bar. If you plan to safely tow a jeep behind motorhome setups, for example, the correct baseplate kit is crucial for strength and alignment.
- Braking systems synchronize the towed car’s brakes with the RV, ensuring both vehicles slow together. Supplemental braking is required by law in many states and is essential for safety when towing on highways or mountain passes.
When picking a towing setup, make sure all parts fit well and meet safety standards.
Step-by-Step: How to Set Up a Towed Vehicle
Before you start your journey, setting up your towed vehicle is crucial. It ensures a smooth towing experience. This process involves several important steps that focus on safety and detail.
Step 1: Hitch Installation and Safety Checks
The foundation of any towing system is the hitch. It must be rated for the combined weight of your motorhome, tow bar or dolly, and the vehicle being towed. Proper installation is critical, an improperly secured hitch can cause the towed car to detach on the highway.
Key checks before you tow your car behind include:
- Confirming the hitch is attached directly to the RV or motorhome frame, not just the bumper.
- Ensuring the hitch height aligns with the tow bar so the setup is level (no more than three inches above or below the baseplate height).
- Tightening all bolts and connections to the manufacturer’s torque specifications.
- Inspecting for rust, cracks, or loose welds that could weaken the mount.
Step 2: Securing the Tow Bar or Dolly Correctly
Once the hitch is confirmed, the next step is connecting the tow bar or dolly. With flat towing, the tow bar attaches directly to the baseplate installed on the towed vehicle’s frame. If you’re towing a jeep or another model that can be flat towed, this step is straightforward but still requires careful inspection.
| Tow Bar/Dolly Component | Securing Method | Safety Check |
| Tow Bar | Connect to the vehicle’s baseplate with locking pins and safety clips | Ensure both arms are locked and cables crossed beneath the hitch |
| Dolly | Position front wheels on ramps and secure with heavy-duty wheel straps | Verify wheels are centered, straps are tight, and safety chains are crossed |
Following these steps ensures the equipment won’t loosen during travel or while maneuvering into a campground.
Step 3: Testing Lights, Brakes, and Tire Pressure
Electrical and braking systems must be tested before every trip. The wiring harness ensures that the towed vehicle’s turn signals, brake lights, and hazard lights function in sync with the RV. Supplemental braking systems should be tested to make sure the RV and towed car stop together, reducing strain on the motorhome’s brakes.
Final Pre-Trip Checks
Here’s some quick final checks to ensure your RV and towed car are fully road-ready
- Verifying that all lights, brake, turn, and hazard are fully operational.
- Engaging the supplemental braking system and confirming that it activates when the motorhome brakes.
- Checking the tire pressure of the towed car or jeep and adjusting to the manufacturer’s recommended PSI.
By following these steps and performing the necessary safety checks, you can ensure a safe and enjoyable towing experience.
Legal and Safety Considerations
Towing a car behind an RV comes with legal and safety rules. Knowing these can help you avoid fines and ensure a safe trip.
State Laws on Towed Vehicle Braking Systems
Most states require supplemental braking systems when you tow your car behind if the towed vehicle exceeds a certain weight. These systems synchronize the towed vehicle’s brakes with the motorhome, reducing stopping distance and preventing excessive strain on the RV’s brakes.
| State | Braking System Requirement | Weight Threshold |
| California | Supplemental braking required | 1,500 lbs |
| Texas | Not required under state law | N/A |
| Florida | Strongly recommended; required for some setups | 2,000 lbs |
| Colorado | Supplemental braking required | 3,000 lbs |
| New York | Supplemental braking required | 1,000 lbs |
If you plan to tow your car behind across multiple states, always check the USA.gov’s Motor Vehicles (DMV) website for current regulations. This page lets you quickly find your state’s DMV website, where you can review the latest towing regulations and requirements. Supplemental braking is not optional in most places, and even in states without specific thresholds, it’s a best practice to install one.
Maximum Towing Speeds and Weight Limits
Every towing method, flat towing, dolly towing, or using a car hauler comes with weight and speed limits. These limits are in place to keep both your motorhome and towed vehicle stable on the road.
| Towing Equipment | Maximum Vehicle Weight | Recommended Speed Limit |
| Tow Bar & Baseplate | 3,500 lbs (vehicles that can be flat towed) | 60 mph |
| Tow Dolly | 4,000 lbs (most front-wheel drive vehicles) | 65 mph |
| Car Trailer / Car Hauler | 5,000+ lbs (any vehicle that fits) | 65 mph |
Exceeding these limits increases the risk of sway, brake failure, and drivetrain damage. Always match your towing setup to your RV’s GCWR (Gross Combined Weight Rating). For instance, a Class A motorhome can typically manage a full-size SUV on a car hauler, while a Class C is better suited for towing smaller vehicles or jeeps that can be flat towed.
Safety Requirements to Always Follow
To safely tow in compliance with both state and federal regulations:
- Cross safety chains under the hitch to prevent the tow bar or dolly from dropping if it disconnects.
- Use a breakaway switch on supplemental braking systems are required in most states to stop the towed vehicle if it detaches.
- Confirm the baseplate, tow bar, and braking system are rated for the exact weight of the vehicle you’re pulling.
- Respect campground rules on speed and vehicle movement, as some prohibit dolly storage in common areas.
By taking legal and safety rules seriously, you can tow your car behind without risking fines, accidents, or liability issues. Proper equipment, compliance with braking laws, and adherence to speed limits ensure that your motorhome setup is road-legal and ready for long-distance travel.
Tips for Safe Driving While Towing Car Behind your RV
Driving a motorhome with a vehicle in tow requires adjustments in handling, braking, and overall awareness. Whether you flat tow a jeep, use a dolly, or pull a car hauler, mastering these techniques ensures that you can safely tow your car behind and arrive without issues.
1. Turning While Towing
Turning with a towed vehicle requires a wider radius. The towed car does not follow the exact path of the motorhome, so you must slow down and give yourself extra clearance. This is especially important when maneuvering through campground loops, fuel stations, or city streets.
2. Braking With Extra Weight
Braking distances increase when towing. Even with a supplemental braking system, the added weight of the towed car demands gradual stops. Anticipate slowdowns earlier and avoid sudden braking to protect both your RV and the baseplate or tow bar setup.
3. Reversing Safely
Flat towing systems cannot be reversed while connected. Attempting this risks damaging the tow bar or baseplate. If you need to back up, disconnect the car first. Dollies and car haulers allow reversing but require slow movements and a spotter to prevent jackknifing.
4. Handling Hills and Descents
On steep grades, use tow/haul mode or lower gears rather than relying on brakes alone. Overheating brakes is one of the most common towing hazards. Managing speed on descents is critical to safely tow, especially when your RV is pulling at or near capacity.
5. Driving in Crosswinds
Crosswinds and passing trucks create added sway. Reduce speed when conditions are windy and maintain both hands on the wheel. Vehicles can be flat towed at highway speeds, but only if you stay within the towing equipment’s speed limits.
6. Speed Control by Towing Method
Each towing method has limits. Tow bars often carry a 60 mph maximum, while dollies and car haulers may allow up to 55 mph. Exceeding these speeds can lead to sway or equipment failure. Always verify the manufacturer’s ratings before a trip.
7. Checking Connections on the Road
Plan regular stops every 100 to 150 miles to inspect your towing setup. Check tow bar pins, safety chains, and wiring harnesses. Confirm that lights are functioning, tires are properly inflated, and braking systems are synced. For jeeps or other vehicles that can be flat towed, confirm transmission settings remain correct throughout travel.
Common Mistakes to Avoid When Towing
Even experienced RV owners can make errors when setting up to tow a car behind motorhome trips. Many of these mistakes come from overlooking small details, but they can cause equipment damage, unsafe driving conditions, or even accidents.
1. Overloading the RV’s Towing Capacity
One of the biggest mistakes is ignoring the motorhome’s towing limits. Pulling more weight than your RV is rated for can overheat the engine, damage the transmission, and make braking unsafe. Always check the Gross Combination Weight Rating (GCWR) before you tow your car behind, especially if using a car hauler that adds significant load.
2. Using the Wrong Towing Method
Not all vehicles can be flat towed, yet owners sometimes attempt it without checking manufacturer guidelines. Towing a car that requires a dolly or trailer without the proper setup can ruin its transmission or drivetrain. For example, many jeeps are designed for flat towing, but sedans and all-wheel-drive vehicles often need a dolly or car hauler.
3. Incorrect Baseplate or Tow Bar Installation
If the baseplate on the towed vehicle is installed incorrectly or the tow bar is misaligned, the connection can fail under stress. This mistake often happens with DIY installations. Always use manufacturer-approved baseplates and ensure the tow bar is level within three inches of the hitch height on the motorhome.
4. Forgetting Supplemental Braking
Some RVers assume their motorhome’s brakes are enough for both vehicles, but this is a dangerous assumption. Without a supplemental braking system, stopping distances increase dramatically. In many states, towing without one is also illegal. To safely tow your car behind, confirm that the braking system is installed, tested, and rated for your setup.
5. Not Checking Lights and Wiring
Another common error is overlooking the wiring harness and light connections. If the towed vehicle’s brake lights and turn signals don’t match the RV’s, other drivers won’t know your intentions. Before leaving a campground or rest stop, always confirm that hazard lights, brake lights, and turn signals are synced correctly.
6. Ignoring Tire Pressure and Wear
Flat towing and dolly towing both place stress on the towed vehicle’s tires. Low tire pressure or uneven wear can lead to blowouts on the highway. Always check and adjust tire pressure before you tow your car behind, and inspect for tread damage at every fuel stop.
7. Attempting to Reverse While Connected
Trying to back up while flat towing is a mistake that can bend tow bars, damage baseplates, or cause the vehicle to jackknife. If reversing is necessary, disconnect the towed car first. With dollies or car haulers, reversing is possible, but only with patience, a spotter, and careful movements.
Conclusion
Towing a car behind a motorhome adds flexibility, safety, and convenience to your RV lifestyle. Whether you choose flat towing for vehicles that can be flat towed, a dolly for front-wheel drive cars, or a full car hauler for maximum protection, the key is matching the right equipment to your RV’s towing capacity.
From navigating campground roads in a small jeep to exploring nearby towns without moving your RV, the benefits of bringing a second vehicle are clear. By avoiding common mistakes, following proper setup steps, and respecting towing limits, you’ll enjoy a smoother, more confident journey every time you tow your car behind.
