how to flat tow a car

Question

EmmettDella · Accepted Answer

Flat towing, also known as dinghy towing, involves pulling a car with all four wheels on the ground behind a motorhome or tow vehicle. The most critical step is verifying your specific car is flat towable; many modern vehicles with automatic transmissions are not, as towing them can cause severe transmission damage due to a lack of lubrication. You must consult your owner's manual or the vehicle manufacturer for explicit approval.

The essential equipment includes a sturdy baseplate mounted to your car's frame, a tow bar that connects to the baseplate, a breakaway switch that automatically applies the car's brakes if it becomes detached, and lighting wiring to sync the towed car's brake and turn signals with the motorhome. Safety checks are paramount. Ensure the tow bar is securely locked, the safety cables are properly attached, and that the steering wheel is unlocked (usually by turning the ignition to the "accessory" or "on" position without starting the engine).

Before hitting the road, practice turning and backing up in a large, empty parking lot to get a feel for the combined length and handling. Make it a habit to do a full walk-around inspection at every stop, checking all connections and tire conditions. Local laws vary, so always confirm towing regulations, including any required additional mirrors, for the states you'll be driving through.

Essential Equipment for Flat Towing	Purpose & Key Considerations
Vehicle-Specific Baseplate	Provides a secure, frame-mounted connection point for the tow bar. Must be model-specific.
Tow Bar	The rigid or folding link between the vehicles. Rigid bars are simpler; folding are easier to store.
Breakaway System	A vital safety device with a battery and switch that engages the towed car's brakes if it separates.
Tail Light Wiring Kit	Ensures the towed car's brake, turn, and tail lights function with the motorhome's signals.
Supplemental Braking System	Often required by law in heavier rigs; it applies the towed car's brakes when the motorhome brakes.
Mirror Extensions	Provide a clear view behind the wider combined vehicle, a legal requirement in many states.

My biggest fear was wrecking my transmission. I learned the hard way that you can't just hook up any car. The manual is your bible—check the "Recreational Towing" section. If it says "no," believe it. For my Jeep, it was a yes. The baseplate install was a weekend project, but the peace of mind knowing it's done right is worth it. Now, the pre-trip check is just part of the routine: lights, brakes, connections. It becomes second nature.

Think of it like a three-part system: the car, the connection, and the driver. First, the car must be designed for it. Second, the hardware—tow bar, baseplate, lights—has to be high-quality and correctly installed. Third, and this is key, the driver needs to adjust. You're now driving a 50-foot train. Gentle acceleration, wider turns, and planning your stops are non-negotiable. It's not difficult, but it demands a different mindset.

Honestly, the most overlooked part is the supplemental brake. Legally, if your towed car weighs over a certain limit—often 1,500 to 3,000 pounds depending on the state—you need a system that activates its brakes. It's not just about legality; it's about safety. Without it, you're relying solely on your motorhome's brakes to stop all that extra weight, which drastically increases stopping distance and wears out your brakes fast. It's an investment that pays for itself in safety.

From a technical standpoint, the permission to flat tow hinges on the transmission and transfer case. A manual transmission is often safe because it's mechanically disconnected in neutral. For automatics, it's trickier; the pump that lubricates the gears is usually engine-driven. If the engine is off, there's no lubrication, leading to rapid overheating and failure. This is why many modern AWD vehicles are not flat-towable. Some 4x4s with a true "Neutral" setting on the transfer case are the exception, as this disengages the drivetrain entirely. Always get manufacturer confirmation.
