Choosing the Best RV Tow Vehicle: A Comprehensive Guide for Every RVer

When it comes to hitting the road in your RV, one of the most critical decisions you’ll make is selecting the best RV tow vehicle for your needs. 

Whether you’re towing a lightweight travel trailer or a massive fifth wheel, your choice of tow vehicle can make or break your RV adventure. 

In this guide, we’ll break down everything you need to know about choosing the perfect tow vehicle, from understanding weight ratings to deciding between gas and diesel, and even exploring whether an air ride system could enhance your experience.

1. Gas vs. Diesel: Which is Better for RV Towing?

The debate between gas and diesel trucks is one every prospective RVer encounters. Here are the key differences to help you decide:

Gas Trucks:

• Pros: Gas trucks are typically less expensive upfront, with lower maintenance costs and more readily available fuel. They’re a great choice for those towing smaller RVs or planning shorter trips.
• Cons: Gas engines tend to have less torque compared to diesels, which means they’re not as efficient when towing heavy loads. They may also experience decreased fuel efficiency under strain.

Diesel Trucks:

• Pros: Diesel engines are known for their high torque, making them ideal for towing heavier trailers, especially in hilly or mountainous terrain. They’re also more fuel-efficient when towing and generally have longer lifespans.
• Cons: Diesel trucks are more expensive upfront and require pricier maintenance. Diesel fuel can also be harder to find in remote areas.

Verdict:

If you’re towing a lightweight travel trailer or only RVing occasionally, a gas truck could be the more budget-friendly choice. For heavy fifth wheels or full-time RVers, a diesel truck often provides better performance and efficiency.

2. Dually vs. Single Rear Wheel: What You Need to Know

Dually (Dual Rear Wheel):

• Pros: Dually trucks offer increased stability and better weight distribution, making them a top choice for towing heavy fifth wheels. The extra tires provide added traction and safety.
• Cons: They can be harder to maneuver in tight spaces, less fuel-efficient, and their wider stance makes them challenging to park.

Single Rear Wheel (SRW):

• Pros: Easier to drive and park, with better fuel efficiency. SRWs are great for towing lighter trailers or for those who use their truck as a daily driver.
• Cons: They lack the stability and weight capacity of a dually, which can be a downside for heavier loads.

Verdict:

For towing large fifth wheels or for full-time RVers, a dually is often worth the trade-offs. For smaller trailers or those who need a daily driver, an SRW may suffice.

3. Truck Sizes: 1/2 Ton, 3/4 Ton, and 1 Ton

1/2 Ton Trucks:

• Best suited for lightweight travel trailers and pop-up campers.
• Examples: Ford F-150, Chevrolet Silverado 1500, Ram 1500.

3/4 Ton Trucks:

• A middle ground for towing midsize travel trailers or small fifth wheels.
• Examples: Ford F-250, Chevrolet Silverado 2500, Ram 2500.

1 Ton Trucks:

• Designed for heavy-duty towing, perfect for large fifth wheels.
• Examples: Ford F-350, Chevrolet Silverado 3500, Ram 3500.

Ford F-450: A Favorite Among RVers

• For those seeking maximum towing power, the Ford F-450 stands out as a favorite. It features larger front brakes for superior stopping power and a tighter turning radius compared to the F-350, making it a great option for maneuvering large RVs or navigating in town.

4. Cab Types and Trim Levels:

The type of cab and trim level can significantly impact your truck’s capabilities and comfort. Extended or crew cabs may reduce payload capacity slightly but offer more passenger space. 

Higher trim levels often add weight due to additional features, which can impact your truck’s GVWR (gross vehicle weight rating) and towing ability. Be sure to balance your need for comfort and luxury with your towing requirements.

Tip: Always check your truck’s towing capacity and payload rating to ensure it can handle your trailer’s weight.

5. Understanding Pin Weight and Tongue Weight

Weight distribution is crucial for safe towing. Here’s a quick breakdown:

• Pin Weight: Refers to the amount of a fifth wheel’s weight that rests on the hitch in the truck bed. Typically 15-25% of the trailer’s total weight. To calculate pin weight accurately, include the weight of your cargo, fluids, and any aftermarket modifications in the trailer. Using a weigh station is the best way to understand your truck’s actual payload and pin weight. Pull onto a scale with and without the trailer connected to measure the difference.
• Tongue Weight: The weight that rests on the hitch ball of a travel trailer. Usually 10-15% of the trailer’s total weight.

Tip: Ensure your tow vehicle’s payload capacity can handle these weights. Overloading your truck can lead to unsafe driving conditions.

6. Gooseneck vs. Standard Fifth Wheel Hitches

Gooseneck Hitches:

• Commonly used for agricultural and industrial trailers.
• Pros: Compact design, leaving more truck bed space. With new options like the Gen Y gooseneck hitch, towing stability and ride comfort have improved dramatically, offering dampening systems that rival standard fifth wheel hitches.
• Cons: Historically not as smooth for towing RVs, but innovations like the Gen Y have narrowed this gap.

Standard Fifth Wheel Hitches:

• Specifically designed for RVs.
• Pros: Offer better stability and a smoother ride compared to traditional goosenecks. Ideal for RVers prioritizing comfort and control.
• Cons: Take up more space in the truck bed and may require additional installation steps.

Verdict:

For traditional RVing, a standard fifth wheel hitch remains the gold standard, but advanced gooseneck options like the Gen Y may be worth exploring for those who want flexibility and smoother rides.

7. Should You Invest in an Air Ride System?

An air ride suspension system can greatly enhance your towing experience:

• Benefits: Provides a smoother ride, reduces wear and tear on your RV, and improves handling and stability.
• Drawbacks: Adds cost and complexity to your setup.

Tip: If you’re planning long trips or towing a heavy trailer, an air ride system can be a worthwhile investment.

8. Braking: Don’t Overlook Stopping Power

Towing isn’t just about pulling—it’s about stopping safely. Here’s what to keep in mind:

• Integrated Trailer Brake Controllers: Many modern trucks come with built-in trailer brake controllers, allowing you to adjust braking force for the trailer directly from the cab.
• Exhaust Brakes: Found on many diesel trucks, these provide additional braking power by using engine resistance, reducing wear on your truck’s brakes.
• Aftermarket Brake Controllers: For trucks without built-in systems, these can be added to ensure your trailer brakes engage properly.

Tip: Always ensure your truck’s braking system is up to the task of stopping both your vehicle and your trailer, especially on steep descents. Burned-out brakes can spell disaster.

9. Key Considerations Before Buying a Tow Vehicle

1. Understand Your Trailer’s Weight: Always know the gross vehicle weight rating (GVWR) and ensure your truck can safely tow it.
2. Plan for the Future: If you plan to upgrade your RV, consider buying a tow vehicle with extra capacity.
3. Consider Your Driving Habits: Will you be driving primarily on highways, or tackling mountainous terrain?
4. Think About Daily Use: If your tow vehicle doubles as a daily driver, you may prioritize maneuverability and fuel efficiency.
5. Factor in Safety Features: Look for integrated trailer brake controllers, tow/haul modes, and advanced safety systems.
6. Weigh Your Vehicle: Visit a weigh station to understand your truck’s actual weight, including passengers, cargo, and any modifications.
