How to Choose Tow Bars For Flat Towing
Flat towing, often called dinghy towing or four-down towing, is the process of pulling a vehicle behind a motorhome with all four wheels on the ground. It is the preferred method for many RVers because it eliminates the need for bulky trailers or tow dollies. However, the safety and success of this setup rely almost entirely on the tow bar. Choosing the right one involves understanding weight ratings, hitch types, and convenience features.
Understand the Two Main Types of Tow Bars
Tow bars generally fall into two categories based on where they are mounted. Your choice will depend on your budget and how often you plan to tow.
Motorhome-Mounted Tow Bars
These are the most popular choice for frequent travelers. The tow bar stays in the RV’s hitch receiver when not in use. They usually feature telescoping arms that make it much easier to hook up the vehicle, even if you aren’t perfectly lined up. Most high-end bars from brands like Blue Ox and Roadmaster fall into this category.
Car-Mounted Tow Bars
These bars are attached to the front of the towed vehicle. They are generally more affordable and are often “universal” in fit. While they are great for occasional use or budget builds, they can be more difficult to align and are often more basic in their feature set. They also require you to find a place to store the bar when you reach your destination and unhook the car.
Weight Capacity and Safety Classes
Every tow bar has a maximum weight rating. Exceeding this rating is dangerous and can lead to equipment failure on the highway. Always check your vehicle’s curb weight and add several hundred pounds for fuel and cargo before selecting a bar.
- Class III: Rated up to 5,000 lbs. Ideal for small cars and compact SUVs.
- Class IV: Rated up to 10,000 lbs. Necessary for full-size trucks, large SUVs, and heavy luxury vehicles.
Always choose a tow bar with a capacity that exceeds your vehicle’s weight. Having a “buffer” ensures that the bar can handle the additional stresses of mountain climbs and sudden braking.
The Importance of Non-Binding Technology
One of the biggest frustrations in flat towing is the “binding” of the tow bar. When the RV and the towed vehicle are on uneven ground—such as a gas station entrance or a gravel campsite—the internal latches of the tow bar can become jammed under tension. Non-binding tow bars feature a design that allows you to release the latches even when the bar is under pressure. If you plan to camp in state parks or off-grid locations, non-binding technology is a must-have feature.
Ease of Use: Self-Aligning Arms
Hooking up a towed vehicle by yourself can be a nightmare without self-aligning arms. Premium tow bars feature arms that can extend and pivot independently. You simply get the car close, attach the arms, and as you pull the RV forward, the arms automatically extend to the correct length and lock into place. This eliminates the need for a second person to “spot” you or guide you into a perfect 1-inch target.
Compatibility with Baseplates
A tow bar does not attach directly to the car’s bumper; it attaches to a baseplate, which is a custom-engineered bracket bolted to the car’s frame. Most tow bar manufacturers design their bars to work seamlessly with their own baseplates. For example, a Roadmaster tow bar fits Roadmaster baseplates perfectly. If you want to mix brands—such as using a Blue Ox bar with a Roadmaster baseplate—you will likely need to purchase an adapter. Always verify compatibility before clicking “buy.”
Integrated Features: Braking and Lighting
Modern tow bars often include integrated features that simplify the overall setup. Some bars, like the Roadmaster Nighthawk, include built-in LED light strips that improve safety. Others, like the NSA Ready Brute, include an integrated surge braking system. Since most states legally require a supplemental braking system for the towed vehicle, an all-in-one bar can save you money and installation time.
Maintenance and Longevity
Because tow bars are exposed to road grime, salt, and rain, they require maintenance. Look for bars with “boots”—rubber covers that protect the telescoping arms from debris. Stainless steel and aluminum components are preferred for their corrosion resistance. Periodically cleaning the arms and applying a dry lubricant will keep the mechanism moving smoothly for years of travel.
Conclusion
Choosing the right tow bar for flat towing comes down to matching the capacity to your vehicle and the features to your travel style. If you tow full-time, invest in a motorhome-mounted, non-binding bar with self-aligning arms. If you only tow once or twice a year, a universal adjustable bar may be sufficient. Regardless of your choice, prioritize safety and ease of use to ensure your RV adventures remain the highlight of your journey.
