The short answer: Towing a vehicle behind a travel trailer, often called “double towing” or “triple towing,” is generally illegal in many jurisdictions and fraught with safety concerns. While legal in some limited circumstances, it requires meticulous planning, specialized equipment, and adherence to strict regulations.
Understanding the Legality of Double Towing
Double towing, also known as triple towing when including the tow vehicle, significantly increases the complexity and risk involved in recreational towing. Before even considering this maneuver, it’s absolutely critical to thoroughly research and understand the laws governing double towing in every state or province you plan to travel through. Regulations vary widely, with some states outright prohibiting it, others allowing it only under specific conditions (e.g., towing only a small boat or motorcycle), and still others having no specific laws at all. However, the absence of a specific law doesn’t imply implicit approval.
Factors influencing the legality include:
- Overall Length Restrictions: Most jurisdictions impose limits on the combined length of all vehicles in a tow setup. Exceeding these limits can result in fines, impoundment of vehicles, and potential liability in accidents.
- Vehicle Weight Restrictions: Each component of the tow setup (tow vehicle, travel trailer, and towed vehicle) has specific weight limits. These include Gross Vehicle Weight Rating (GVWR), Gross Combination Weight Rating (GCWR), and axle weight ratings. Exceeding any of these limits is dangerous and often illegal.
- Specific Vehicle Types Allowed: Some states restrict double towing to only certain types of vehicles, such as boats, motorcycles, or ATVs. Towing a car behind a travel trailer may be specifically prohibited.
- Driver’s License Requirements: Operating a double tow setup may require a special driver’s license endorsement or commercial driver’s license (CDL), depending on the combined weight and configuration.
- Safety Equipment Requirements: Regulations often dictate the types of hitches, brakes, and safety chains required for each component of the tow setup.
Failure to comply with double towing regulations can result in severe penalties, including fines, impoundment of vehicles, and potential liability in the event of an accident. It is your responsibility to know and abide by all applicable laws.
The Safety Concerns of Double Towing
Even in jurisdictions where double towing is legal, it presents significant safety challenges. The added length and weight of a double tow setup dramatically increase the risk of accidents.
Increased Stopping Distance
The additional weight significantly increases the stopping distance, requiring greater anticipation and smoother braking. Emergency stops become exponentially more difficult and potentially dangerous. A properly functioning and correctly adjusted braking system on all axles of both the travel trailer and the towed vehicle is absolutely essential.
Reduced Maneuverability
Double towing makes maneuvering in tight spaces, such as campgrounds, gas stations, and parking lots, extremely challenging. Turns require wider clearances, and backing up becomes significantly more difficult. The risk of jackknifing or causing damage to the vehicles is substantially increased.
Increased Sway and Instability
The more vehicles involved in a tow setup, the greater the risk of sway and instability. Sway can be triggered by wind gusts, uneven road surfaces, or sudden maneuvers. A proper weight distribution hitch and sway control system are crucial for mitigating sway, but they are not a guaranteed solution.
Mechanical Failure Risks
The added strain on the tow vehicle, travel trailer, and associated components increases the risk of mechanical failures, such as tire blowouts, hitch failures, and brake system malfunctions. Regular inspections and maintenance are essential to prevent these failures.
Essential Equipment for Double Towing (If Legal and Advised)
If, after thorough research and consideration, you determine that double towing is legal in your area and you are prepared to undertake the associated risks, the following equipment is essential:
- Heavy-Duty Tow Vehicle: The tow vehicle must have sufficient towing capacity and be equipped with a powerful engine, heavy-duty suspension, and a robust braking system.
- Properly Rated Hitches: Both the main hitch connecting the tow vehicle to the travel trailer and the hitch connecting the travel trailer to the towed vehicle must be rated to handle the combined weight of the vehicles.
- Weight Distribution Hitch: A weight distribution hitch is essential for distributing the weight evenly across the axles of the tow vehicle and travel trailer, improving stability and handling.
- Sway Control System: A sway control system helps to dampen sway and prevent it from escalating into a dangerous situation. Electronic sway control systems are generally considered more effective than friction-based systems.
- Auxiliary Braking System: An auxiliary braking system is required for the towed vehicle to provide supplemental braking power and reduce the load on the tow vehicle’s brakes.
- Safety Chains and Cables: Multiple sets of safety chains and breakaway cables are necessary to ensure that the towed vehicle remains connected in the event of a hitch failure.
- Tire Pressure Monitoring System (TPMS): A TPMS is highly recommended to monitor the tire pressure and temperature of all tires in the tow setup, alerting you to potential problems before they lead to a blowout.
- Extended Mirrors: Extended mirrors are essential for providing adequate visibility around the travel trailer and towed vehicle.
FAQs About Towing Behind a Travel Trailer
1. What are the legal length limits for double towing?
Length limits vary significantly by state and province. Some jurisdictions have overall length limits that encompass the entire tow setup, while others have separate limits for each component. Always consult the specific regulations of each jurisdiction you will be traveling through.
2. Does my driver’s license allow me to double tow?
Depending on the combined weight and configuration of your tow setup, you may need a special driver’s license endorsement or a Commercial Driver’s License (CDL). Check with your state’s Department of Motor Vehicles (DMV) or equivalent agency to determine the specific requirements.
3. What is the maximum weight I can tow behind my travel trailer?
The maximum weight you can tow behind your travel trailer depends on several factors, including the GVWR and GCWR of your tow vehicle and travel trailer, as well as the hitch rating. Never exceed any of these weight limits. Consult your vehicle and hitch manufacturer’s specifications for accurate information.
