Towing a vehicle behind your RV requires more than just a sturdy piece of metal. It demands a precision-engineered system that ensures stability, safety, and ease of use during long hauls. Roadmaster has long been a leader in the supplemental towing industry, offering a variety of base plates and tow bars designed to turn your car into a reliable dinghy. However, choosing the right setup is not a one-size-fits-all endeavor. A tow bar that works perfectly for a compact sedan might be entirely unsuitable for a heavy SUV or a front-wheel-drive crossover. This guide will help you navigate the technical nuances of selecting a Roadmaster tow bar system that matches your vehicle's specific drivetrain, weight, and mounting requirements.

Motorhome owners who refuse to compromise on vehicle aesthetics need the Roadmaster MX Series Hidden Brackets to maintain a clean, factory look while towing.

I love how the front arms can be swapped out in seconds just by pulling two hitch pins, instantly converting your car back to its standard appearance. The installation process is a massive relief because it utilizes existing undercarriage attachment points, meaning you can skip the welding entirely. Since most setups install through the grille, you won't have to worry about scraping your hardware on curbs or dips.

Buying Guide

A Guide to Selecting the Best Roadmaster Car Tow Bars

A Guide to Selecting the Best Roadmaster Car Tow Bars

Understanding Drivetrain Compatibility

The most critical decision you will make is matching the tow bar to your vehicle's drivetrain. Roadmaster designs systems specifically for different configurations: Front-Wheel Drive (FWD), Rear-Wheel Drive (RWD), and All-Wheel Drive (AWD). For FWD vehicles, the tow bar must work in tandem with a base plate that allows the front wheels to spin freely while the vehicle is being pulled. For RWD or AWD vehicles, the setup often requires a different approach to ensure the transmission is not damaged during transit. Attempting to use a setup not specifically engineered for your drivetrain can lead to catastrophic mechanical failure in your towed vehicle's transmission.

Weight Capacity and Structural Integrity

Not all cars are created equal when it comes to weight. When browsing Roadmaster options, you must look closely at the Gross Vehicle Weight (GVW) of your towed car. A tow bar designed for a lightweight subcompact may not have the structural rigidity or the rated capacity to handle a mid-sized SUV. Look for high-strength steel construction and robust pin designs. A higher weight capacity provides a safety margin, but you should never exceed the maximum capacity specified by the manufacturer. Always cross-reference your vehicle's curb weight with the tow bar's rated capacity to ensure a safe towing ratio.

Attachment Mechanisms: Base Plates vs. No-Base Plate

Roadmaster offers various mounting philosophies. Most traditional setups involve a base plate that bolts to the vehicle's frame, providing a secure mounting point for the tow bar arms. This is generally the most stable method for long-distance travel. However, some users prefer setups that minimize visible modifications to the vehicle. When deciding, consider how much you value the aesthetic integrity of your car versus the absolute security of a frame-mounted base plate. Remember, the more secure the connection to the vehicle's chassis, the less likely you are to experience 'wobble' or 'sway' while driving.

Ease of Setup and Disconnection

If you are a frequent traveler, the time it takes to hook up and unhook your vehicle can become a significant frustration. Look for Roadmaster models that feature ergonomic handles, easy-to-use locking pins, and streamlined braking systems. Some advanced models include integrated braking systems that make the transition from driving to towing seamless. Evaluate how much manual labor you are willing to perform each time you reach your destination. A system that requires heavy lifting or complex tool usage may become a burden on long road trips.

Safety Features and Braking Systems

A tow bar is only one part of a complete towing solution. To comply with most state laws and to ensure safety, your car tow bar setup should ideally integrate with a supplemental braking system. Roadmaster provides options that sync the braking of the towed vehicle with the braking of your RV. When selecting your bar, consider whether you want a setup that is compatible with electric or hydraulic braking systems. A well-integrated system ensures that your towed vehicle doesn't 'push' your RV during sudden stops, which is vital for maintaining control in emergency maneuvers.

Frequently Asked Questions

Quick answers about Roadmaster Car Tow Bars before you buy.

Weight-carrying bars are simpler and rely on the vehicle's hitch to support the tongue weight, whereas weight-distributing bars use spring bars to spread the load across the vehicle's axles, improving stability and handling.

Not necessarily, but the hitch must be rated for the specific tongue weight and total towing capacity of the tow bar you select to ensure safe operation.

Size is determined by the width of your vehicle's frame and the distance between the mounting points. Always measure your frame width before purchasing to ensure a secure fit.

Yes, but you must ensure the vehicle is set up for flat towing, which often requires disconnecting the driveshaft or using a specific supplemental braking system to prevent transmission damage.

Some models offer easier installation through existing mounting points, reducing the need to drill into your vehicle's frame, which helps preserve the vehicle's structural integrity and resale value.

Yes, for safety and legal compliance, most flat towing setups require a supplemental braking system to ensure the towed vehicle's brakes engage when the lead vehicle slows down.

You should perform a visual inspection before every trip to check for loose bolts, worn straps, or signs of metal fatigue, and a more thorough mechanical inspection at least once a year.

While the bar itself has minimal aerodynamic impact, the added weight and wind resistance of the towed vehicle will result in a noticeable decrease in overall fuel efficiency.
