If the objective is to buy one high-quality tow bar that will last for the lifetime of multiple vehicles, the Sterling is the primary contender.

Your Full Dinghy Setup: More Than Just a Tow Bar

A tow bar is merely one component of a larger system required for legal and safe flat towing. The baseplate, which is the frame-mounted bracket on the front of the towed vehicle, must be specifically engineered for that exact make, model, and year. Do not attempt to universalize this part; the safety of the connection depends on a precise, vehicle-specific fit.

Beyond the hardware, supplemental braking is mandatory in almost all jurisdictions when towing a vehicle behind a motorhome. Modern systems range from portable, floor-mounted units to permanent, hard-wired systems that activate the car’s brakes proportionally to the motorhome’s braking. Ignoring this requirement is a significant safety hazard that places undue stress on the motorhome’s braking system and increases stopping distances to dangerous levels.

Finally, consider the auxiliary lighting system. Whether using magnetic tow lights or a diode kit that taps into the towed vehicle’s own tail lights, ensure all signals are visible. A complete dinghy setup also requires breakaway cables, which act as a failsafe to activate the towed vehicle’s brakes should the tow bar ever separate from the hitch.

Understanding Tow Bar Ratings and Vehicle Weight

Every tow bar has a specific weight rating, and exceeding this limit is a dangerous practice that can lead to catastrophic hardware failure. Always calculate the weight of the towed vehicle while it is in its “travel-ready” state, including all gear, fluids, and aftermarket additions. Never assume the base curb weight is sufficient, as internal cargo can quickly add hundreds of pounds.

The weight rating of the tow bar must also be compatible with the RV’s receiver hitch rating. If the tow bar is rated for 10,000 pounds but the motorhome hitch is only rated for 5,000 pounds, the system is limited to the lower number. Always defer to the lowest-rated component in the entire towing chain, as that is the true point of failure.

Pay close attention to “tongue weight” versus “towing capacity” if the rig uses a drop-down receiver or an extension. Extensions significantly reduce the hitch’s capacity, sometimes by as much as 50 percent. When in doubt, consult the manufacturer’s documentation for the motorhome to understand the specific limits of the chassis and factory hitch assembly.

The Pre-Trip Hookup and Safety Checklist

A consistent pre-trip checklist prevents the most common towing mistakes, such as leaving the transmission in the wrong gear or forgetting to plug in the lighting harness. Always verify the vehicle’s specific owner’s manual for “flat towability,” as some vehicles require specific fluid pump installations or transmission settings to avoid catastrophic mechanical damage. Failure to follow these manufacturer-specific procedures can void a warranty and lead to thousands of dollars in transmission repairs.

Before departing, perform a “pull test” by manually checking that both arms of the tow bar are locked in place. Ensure the safety cables are crossed underneath the hitch to form a cradle, preventing the tow bar from dropping to the pavement if it detaches. Verify that the auxiliary braking system is active and that the breakaway cable is securely attached to a solid point on the motorhome frame—never to the tow bar itself.

Double-check the lighting sequence: left turn, right turn, brakes, and running lights. Have an assistant walk around the towed vehicle while the RV lights are cycled to confirm each signal. A few minutes spent verifying these connections prevents both mechanical failures and potential traffic citations during the journey.

How to Maintain Your Tow Bar for a Long Life

Tow bars endure extreme vibration, road salt, and debris, making regular maintenance essential for long-term safety. After every long trip, inspect the pivot points for signs of metal fatigue, stress cracks, or loose hardware. Lubricate the moving parts with a dry lubricant—avoid using thick greases that attract road grit and turn into an abrasive paste.

If the tow bar uses rubber boots to protect the internal sliding mechanisms, check them frequently for tears or dry rot. A damaged boot allows moisture and sand to enter the telescoping arms, which can lead to binding or internal corrosion. If a boot is damaged, replace it immediately to preserve the integrity of the inner components.

Store the tow bar properly when it is not in use to extend its lifespan. Many models can be folded onto the back of the motorhome and secured with a cover; this protects the finish from environmental elements and road grime. A well-maintained tow bar is a reliable tool, while one left to weather and rust will eventually become a liability on the open road.

Selecting the right tow bar is an essential step in ensuring your mobile lifestyle remains as stress-free as possible. By prioritizing the specific needs of your vehicle and your travel style, you can secure a connection that performs reliably for years. Invest in quality hardware, maintain it with diligence, and enjoy the added mobility that flat towing brings to your RV experience.

Frequently Asked Questions (FAQs)

What is a motorhome mounted tow bar for flat towing?

A motorhome-mounted tow bar inserts directly into the RV hitch receiver and stays on the coach when unhooked. This design folds flat against the back of the motorhome to save storage space. Brands like Blue Ox and Roadmaster build these with integrated non-binding release handles so you can unlatch your car on uneven ground.

What does non-binding mean on a tow bar for RV travel?

Non-binding tow bars feature mechanical release levers that disconnect your dinghy vehicle easily, even when parked on unlevel gravel or turned at sharp angles. Traditional latching bars bind under tension when the RV and toad are not perfectly straight. Upgrading to non-binding arms prevents you from needing to hammer release pins loose or shift the car to relieve pressure at campsites.

How do I hook up a tow bar for flat towing a car behind an RV?

Hooking up a tow bar requires aligning the RV receiver hitch, inserting the safety pins, and extending the telescoping arms into the vehicle baseplate. Next, lock the arm pins in place, attach two crossed safety cables, plug in the electrical umbilical cord, and connect the supplemental braking system breakaway cable. Finally, drive the motorhome slowly forward until both arms click into their fully extended, locked position.

How long does it take to connect a tow bar at a campsite?

Connecting a modern tow bar setup typically takes between five and ten minutes once you become familiar with the steps. Most of that time is spent positioning your vehicle straight behind the motorhome and configuring the car transmission for flat towing, such as shifting into neutral. Disconnecting at your campsite is even faster, often taking less than three minutes to pull the pins and coil the cables.

Which is better a tow bar or a tow dolly for RV travel?

Tow bars are better than tow dollies for RV travelers who prioritize quick hookups, reduced road weight, and minimal campsite storage needs. A tow bar pulls all four wheels on the pavement and stores against the motorhome bumper. Tow dollies carry only the front tires, work with front-wheel-drive cars that cannot be flat-towed, but require manual loading, securing wheel straps, and storing a bulky trailer.

How much does a complete tow bar setup cost for flat towing?

Total costs for a complete flat towing setup range from $2,500 to $4,500 including the tow bar, baseplate, wiring, and supplemental braking system. A quality tow bar alone costs between $700 and $1,400 depending on weight capacity, which usually ranges from 6,000 to 10,000 pounds. Professional installation adds $800 to $1,500 in labor, especially for mounting custom baseplates to the vehicle frame.

Why won’t my tow bar unlatch when disconnecting from the RV?

Binding occurs when tension builds inside the tow bar arms because the RV and towed vehicle are stopped on uneven terrain or at an angle. To release stuck pins, start your towed car’s engine and gently roll it forward or turn the steering wheel slightly toward the tight arm to relieve the binding pressure. If you do not have non-binding release levers, carry a rubber mallet as a backup tool.

Is an auxiliary braking system legally required with a tow bar?

Auxiliary braking systems are legally required for flat towing in nearly all US states and Canadian provinces when the towed vehicle exceeds specific weight thresholds. Most jurisdictions set this legal limit between 3,000 and 4,000 pounds, which encompasses almost every passenger car, SUV, or truck. Installing a proportional braking unit like the Roadmaster InvisiBrake prevents catastrophic runaway accidents and keeps your RV warranty intact.
