Single Axle vs. Tandem Axle Enclosed Trailers: Which Size is Best for My Needs?

Single Axle vs. Tandem Axle Enclosed Trailers: Which Size is Best for My Needs?

Choosing between a single axle or tandem axle enclosed trailer isn't just about specs—it's about finding the right fit for your specific needs. Both designs have their strengths, and the best choice ultimately depends on what you're hauling, where you're going, and how much you can afford to spend. Understanding these key differences will help you make a choice you won't regret down the road.

What's the Difference Between Single and Tandem Axle Trailers?

At its core, a single axle trailer has one axle with two wheels, making it lighter and ideal for small jobs. Single axles are perfect for lighter loads like lawnmowers, small business equipment, or household items. If you're only hauling occasional weekend gear, this might be all you need.

A tandem axle trailer features two axles and four wheels, offering better support for heavier loads and improved stability. When weight matters, these provide the muscle you need. If you’re hauling ATVs, heavy equipment for a business, or oversized personal items, a tandem axle cargo trailer is the way to go. Plus, tandem axles have electric brakes that improve control by applying proportional braking force to the trailer’s wheels, reducing sway and strain on the tow vehicle.

Match the Trailer’s GVWR to Your Hauling Needs

GVWR is the maximum weight a trailer can handle, including its own weight and cargo. To determine whether you need a single axle or tandem axle enclosed trailer, subtract the trailer’s empty weight from its GVWR. Never leave getting the right trailer to guesswork. As trailer specialists at TrailersPlus, we can check the manufacturer’s listed weight. For example:

• A John Deere 1025R sub-compact tractor weighs approximately 1,450 lbs without attachments. A 6x10 single axle trailer could handle it, but a tandem axle might be a better option if you plan to carry additional equipment.
• A Harley-Davidson Road Glide weighs around 850 lbs. If you’re hauling two motorcycles, a single axle trailer may work, but a tandem axle trailer offers better stability on long trips, ensuring you make the best investment today.

Example Comparisons

6x10 Single Axle Enclosed Trailer

• GVWR: 2,990 lbs
• Empty Trailer Weight: 1,167 lbs
• Payload Capacity: 1,823 lbs

7x14 Tandem Axle Enclosed Trailer

• GVWR: 7,000 lbs
• Empty Trailer Weight: 2,246 lbs
• Payload Capacity: 4,754 lbs

Maneuverability & Towing Experience

Need to navigate tight city streets or narrow driveways? Single axle trailers shine here, especially if you're using a smaller tow vehicle. Tandem axles provide rock-solid stability at highway speeds but require more room to turn. They're less forgiving in tight spots, something to consider if your routes involve narrow passages.

If you're new to towing, you'll likely find backing up and parking easier with a single axle trailer.

Stability & Road Performance

The right parts and accessories go a long way with the right trailer. If you’re concerned about sway with your enclosed cargo trailer, pick up an Andersen weight distribution hitch at TrailersPlus. The no-sway, no-bounce motion-dampening chains are a game-changer, worth the investment.

Single axles might feel less stable when fully loaded, particularly on:

• Long highway trips
• Mountain roads
• Uneven terrain
• Windy conditions

If you blow a tire, a tandem axle trailer gives you a major safety advantage—the second axle helps maintain control while you find a safe place to stop.

Cost & Long-Term Value

Think of a new enclosed trailer as an investment and how often you will be hauling cargo.

Single axle trailers win on initial price and maintenance costs with fewer tires and bearings to replace. They're the budget-friendly choice for occasional users. Because they have a single set of wheels, they are also easier to maneuver and tow with smaller vehicles. However, they have weight limitations and may not provide the same level of stability on highways or rough terrain.

Tandem axles cost more upfront but often deliver better long-term value if you're hauling frequently or carrying substantial loads. The extra set of wheels distributes weight more evenly, improving stability, ride quality, and overall durability. They also typically come equipped with brakes, enhancing safety when towing heavier cargo. If you plan to make long trips, travel on highways regularly, or need to transport heavy or fragile goods, the added cost may be justified by improved performance and longevity.

When to Choose a Single Axle Trailer

You're likely better off with a single axle when your cargo is typically small and lightweight. You need something maneuverable for tight spaces. Your towing vehicle has limited capacity.

Budget constraints are a significant factor, and most of your trips stay local. Single axles deliver simplicity when you don't need the extra capabilities of a tandem.

When to Choose a Tandem Axle Trailer

A tandem axle makes more sense when heavy loads are the norm for you. You'll appreciate the added stability if you regularly travel long distances or tackle rough roads. Safety becomes even more critical when transporting valuable cargo. Business owners and contractors often find the additional investment pays dividends through reliability and reduced risk.
