Unlocking Your Move: The Definitive Guide to U-Haul Open Trailer Sizes, Chart & Dimensions

Why an Open Trailer Might Be Your Best Bet

When considering your moving or hauling options, an open trailer often presents unique advantages over enclosed trailers or traditional moving trucks for certain types of cargo. Its design offers unparalleled flexibility and ease of access, which can be a game-changer depending on what you’re transporting.

Open trailers are particularly well-suited for items that are oddly shaped, excessively tall, or simply won’t fit comfortably into an enclosed space. Think about a towering armoire, a large outdoor playset, or even construction materials like lumber or piping that extend beyond standard dimensions. Their open-air nature means you’re not confined by a roof, providing more headroom and versatile loading possibilities.

Furthermore, these trailers are a go-to choice for transporting recreational vehicles such as motorcycles, ATVs, dirt bikes, or even small lawn tractors. The integrated ramps on many U-Haul utility trailers make loading and unloading these wheeled items significantly easier and safer. This convenience often translates to saved time and effort, particularly for those who frequently move such equipment.

Demystifying U-Haul’s Open Trailer Lineup: Utility vs. Car Haulers

U-Haul primarily offers two main categories of open trailers: utility trailers and car haulers. While both are designed for open-air transport, their primary functions and structural designs differ significantly. Understanding this distinction is the first step in selecting the right equipment.

Utility Trailers are your versatile workhorses, designed for moving a wide array of household goods, yard waste, furniture, appliances, and recreational equipment. They come in various sizes, often featuring low decks and sturdy side rails, with some models including a convenient ramp for roll-on loading. These trailers are ideal for general hauling tasks where you need ample space and easy access.

Car Haulers, on the other hand, are specifically engineered for transporting vehicles. This category includes both the full Auto Transport trailers and the more compact Tow Dollies. Their design prioritizes secure vehicle transport, featuring specialized ramps, tie-down points, and robust construction to handle the weight and dimensions of cars, trucks, and SUVs. Choosing between these depends on the type of vehicle you’re moving and the distance of your journey.

The Heart of the Matter: U-Haul Utility Trailer Sizes Chart & Dimensions

Let’s dive into the specifics of U-Haul’s utility trailer offerings. Each size is designed with particular hauling needs in mind, offering different dimensions and capacities. Knowing these details is crucial for a successful and safe tow.

1. The Nimble 4×7 Utility Trailer

The 4×7 utility trailer is U-Haul’s smallest open trailer option, making it surprisingly agile and easy to maneuver. Don’t let its compact size fool you; it’s a mighty helper for a variety of tasks where larger trailers would be overkill.

• Interior Bed Dimensions (LxW): Approximately 7’2" x 4’1" (2.18m x 1.24m)
• Deck Height: Around 1’8" (0.51m) from the ground, making it relatively easy to load items without a ramp.
• Max Load Capacity: Often around 1,500 lbs (680 kg), but always verify the exact rating at the time of rental.
• Empty Weight: Approximately 600 lbs (272 kg).
• Features: Typically comes with sturdy side rails to help secure your load. It’s often referred to as a "flatbed" trailer due to its simple, open design.
• Ideal Uses: Based on my experience, this trailer is perfect for small-scale projects. It excels at transporting bags of soil, gardening tools, a few pieces of small furniture like nightstands or chairs, boxes, camping gear, or clearing out yard debris. It’s also a popular choice for college students moving a few belongings to and from dorms.

This trailer is particularly forgiving for first-time towers due to its lighter weight and smaller footprint. However, a common mistake people make is trying to squeeze too much into it, exceeding the weight limit. Always prioritize safety and stay within the stated capacity.

2. The Versatile 5×8 Utility Trailer

Stepping up in size, the 5×8 utility trailer offers a significant increase in hauling capacity and versatility. This is often the go-to choice for individuals needing more space than the 4×7 but not requiring a much larger rig.

• Interior Bed Dimensions (LxW): Approximately 8’1" x 5’0" (2.46m x 1.52m)
• Deck Height: Similar to the 4×7, around 1’8" (0.51m), maintaining ease of loading.
• Max Load Capacity: Typically around 1,650 lbs (748 kg). Always double-check the specific trailer’s rating.
• Empty Weight: Approximately 900 lbs (408 kg).
• Features: Like its smaller counterpart, it features side rails. Some 5×8 models may come with an integrated ramp, significantly enhancing their functionality for rolling items.
• Ideal Uses: This trailer is incredibly versatile. It’s well-suited for moving larger furniture pieces like sofas, dressers, or queen-sized mattresses. It can comfortably transport a standard ATV, a riding lawnmower, or a significant amount of construction debris. Many small businesses use this size for local deliveries or hauling equipment to job sites.

Pro tips from us: When loading items into a 5×8, always think about weight distribution. Placing heavier items over the axle helps maintain stability and reduces sway. If your specific 5×8 has a ramp, utilize it for anything with wheels to save your back and prevent injury.

3. The Ramp-Equipped 5×9 Utility Trailer

The 5×9 utility trailer with a ramp is a specialized option designed with convenience and functionality in mind, especially for rolling cargo. While its overall dimensions are close to the 5×8, the integrated ramp feature sets it apart.

• Interior Bed Dimensions (LxW): Approximately 9’2" x 5’0" (2.79m x 1.52m)
• Deck Height: Often lower than other utility trailers, sometimes around 1’6" (0.46m), specifically to facilitate ramp loading.
• Max Load Capacity: Typically around 1,650 lbs (748 kg), similar to the 5×8, but the focus here is on the ease of loading wheeled items.
• Empty Weight: Approximately 900 lbs (408 kg).
• Features: The defining feature is the sturdy, fold-down ramp at the rear, making it incredibly easy to load motorcycles, ATVs, dirt bikes, lawnmowers, or even heavy appliances on a dolly.
• Ideal Uses: This is the ultimate choice for anyone transporting motorcycles, scooters, or small utility vehicles. It’s also excellent for moving bulky items that are difficult to lift, such as washing machines, refrigerators, or large tool chests, by simply rolling them up the ramp with a hand truck.

Based on my experience, for anyone moving a motorcycle, this trailer is almost a non-negotiable. The peace of mind and ease of loading it provides are well worth it. Just ensure your motorcycle is securely tied down using multiple points to prevent any movement during transit.

4. The Capacious 6×12 Utility Trailer

The 6×12 utility trailer represents U-Haul’s largest open utility trailer, providing substantial space for bigger moves and heavier loads. When you have a significant amount of items that won’t fit into smaller options, this is your solution.

• Interior Bed Dimensions (LxW): Approximately 12’0" x 6’2" (3.66m x 1.88m)
• Deck Height: Still relatively low, around 1’8" (0.51m), for convenient loading.
• Max Load Capacity: Can range from 2,500 lbs (1,134 kg) up to 3,000 lbs (1,360 kg) or more, depending on the specific model. Always confirm the exact capacity directly from U-Haul.
• Empty Weight: Approximately 1,300 lbs (590 kg).
• Features: This trailer typically features sturdy side rails and often comes equipped with a ramp for easy loading of larger wheeled items or heavy objects. Its larger footprint makes it suitable for diverse hauling needs.
• Ideal Uses: This size is perfect for moving the contents of a small apartment, large quantities of landscaping materials, multiple ATVs or dirt bikes, or even a small utility vehicle. It’s a favorite for contractors needing to transport significant amounts of tools, lumber, or equipment to a job site.

When considering this size, always factor in your towing vehicle’s capabilities. This trailer, especially when fully loaded, will exert significant weight. Ensure your tow vehicle has the necessary towing capacity, hitch class, and a proper braking system. For more comprehensive towing advice, see our article on .

The Heavy Lifters: U-Haul Car Hauler Sizes Chart & Dimensions

For transporting vehicles, U-Haul offers specialized open trailers designed for security and stability. Choosing between an Auto Transport and a Tow Dolly depends on your vehicle type, towing vehicle, and distance.

1. The Robust Auto Transport Trailer (Full Car Trailer)

The U-Haul Auto Transport is a full-sized car trailer designed to carry an entire vehicle securely on its own four wheels, making it ideal for non-drivable cars or long-distance moves.

• Usable Deck Dimensions (LxW): Approximately 14’8" x 6’9" (4.47m x 2.06m) between the fenders. The total length can be significantly longer.
• Fender-to-Fender Width: Roughly 6’9" (2.06m), which is a critical measurement for vehicle compatibility.
• Overall Length: Can be up to 20 feet or more, including the tongue.
• Max Load Capacity: Typically around 5,290 lbs (2,400 kg), but this can vary. It’s crucial to check the specific trailer’s capacity and ensure it accommodates your vehicle’s curb weight.
• Empty Weight: Approximately 2,210 lbs (1,002 kg).
• Features: Equipped with integrated ramps, heavy-duty tie-down straps for all four wheels, and often a surge brake system for added safety.
• Ideal Uses: From my perspective, this offers the most security and peace of mind for transporting valuable or non-operational vehicles. It’s perfect for cross-country moves, transporting classic cars, or moving vehicles that cannot be driven. It handles a wide range of cars, trucks, and SUVs.

A common oversight with auto transports is neglecting to confirm your towing vehicle’s capacity. These trailers, especially with a vehicle loaded, are heavy. Your tow vehicle needs a robust towing capacity, typically a full-size truck or a heavy-duty SUV, and often requires a Class III or IV hitch.

2. The Economical Tow Dolly

The U-Haul Tow Dolly is a simpler, more compact, and often more economical option for transporting vehicles, primarily designed for front-wheel-drive cars. It lifts the front wheels of the towed vehicle off the ground while the rear wheels remain on the road.

• Max Wheel Base: The towed vehicle must fit within a maximum wheel base, typically around 79" (2.0m).
• Max Tread Width: The towed vehicle’s tread width (outer edge of tire to outer edge of tire) usually needs to be between 40" and 76" (1.02m and 1.93m).
• Overall Length: Significantly shorter than an auto transport, making it easier to maneuver.
• Max Load Capacity: Typically around 3,450 lbs (1,565 kg). This is the weight of the towed vehicle, not including the dolly’s own weight.
• Empty Weight: Approximately 650 lbs (295 kg).
• Features: Comes with integrated ramps and heavy-duty straps to secure the front wheels of the towed vehicle.
• Ideal Uses: While cost-effective, a common oversight with tow dollies is attempting to tow a rear-wheel-drive or all-wheel-drive vehicle without proper precautions (like disconnecting the driveshaft). It is best suited for front-wheel-drive vehicles, particularly for shorter distances, or when your towing vehicle’s capacity is limited.

Always consult the U-Haul guidelines for specific vehicle compatibility with a tow dolly. Improper use can lead to serious damage to the towed vehicle’s transmission or drivetrain.

Key Factors When Choosing Your U-Haul Open Trailer

Selecting the right U-Haul open trailer goes beyond just looking at a chart. Several critical factors must be carefully considered to ensure a safe, efficient, and hassle-free experience. Overlooking any of these can lead to complications, delays, or even safety hazards.

1. What Are You Moving? (Size, Shape, Weight)

This is the most fundamental question. Begin by making an inventory of everything you intend to transport. Measure the longest, widest, and tallest items.

• Dimensions: Will your oversized couch fit between the fender wells of an auto transport? Can your ATV clear the side rails of a utility trailer?
• Weight: Estimate the total weight of your cargo. Remember that stated capacities are for the cargo itself, not including the trailer’s empty weight. Always err on the side of caution and round up your estimates.
• Nature of Items: Are they fragile? Bulky? Wheeled? This will influence whether you need ramps, extra tie-downs, or specific trailer types.

2. Total Weight Calculation: Payload vs. Towing Capacity

Understanding the difference between payload and towing capacity is paramount.

• Payload Capacity: This is the maximum weight of cargo the trailer can safely carry. Exceeding this is dangerous and often illegal.
• Gross Trailer Weight (GTW): This is the total weight of the trailer itself (empty weight) PLUS the weight of your cargo (payload).
• Towing Capacity: This is the maximum GTW your towing vehicle is rated to pull. This figure is determined by the vehicle manufacturer and should never be exceeded.

Always calculate the GTW before renting. For instance, if a 6×12 utility trailer weighs 1,300 lbs empty and you load 2,000 lbs of furniture, your GTW is 3,300 lbs. Your towing vehicle must be rated to pull at least this much.

3. Towing Vehicle Compatibility: The Unsung Hero

Your tow vehicle is just as important as the trailer itself. It must be adequately equipped and rated for the task.

• Hitch Class and Rating: Ensure your vehicle has a hitch receiver rated for the Gross Trailer Weight (GTW) you calculated. U-Haul trailers typically require a Class I, II, III, or IV hitch, depending on the trailer size.
• Hitch Ball Size: U-Haul trailers usually require either a 1-7/8" or a 2" hitch ball. Confirm the correct size for your chosen trailer.
• Electrical Connector: Your vehicle needs a working 4-flat electrical connector to power the trailer’s brake lights, turn signals, and running lights. This is a legal and safety requirement.
• Vehicle Curb Weight and GVWR: Your tow vehicle’s curb weight should ideally be greater than the GTW of the trailer for optimal stability and control. Also, be mindful of your vehicle’s Gross Vehicle Weight Rating (GVWR), which includes the vehicle’s weight, passengers, and cargo.
• Transmission Cooler: For heavier loads or long distances, a transmission cooler is highly recommended to prevent your vehicle’s transmission from overheating.

4. Distance of Travel: Local Hop vs. Cross-Country Trek

The length of your journey influences your trailer choice and preparation.

• Local Moves: For short distances, some flexibility might exist, but safety is still paramount.
• Long Hauls: For cross-country trips, stability, durability, and robust towing capacity become even more critical. A full auto transport is generally preferred over a tow dolly for long-distance vehicle transport due to less wear and tear on the towed vehicle’s rear tires.

5. Loading and Unloading Needs: Ramps and Tie-Downs

Consider how you’ll get items onto and off the trailer.

• Ramps: If you’re moving wheeled items (motorcycles, lawnmowers) or heavy appliances, a trailer with an integrated ramp (like the 5×9 or larger utility trailers, or auto transports) is invaluable.
• Tie-Downs: Ensure you have enough high-quality ratchet straps or ropes to secure your load. U-Haul trailers have tie-down points, but you’ll need your own securing equipment.

6. Budget Considerations

While safety and suitability are primary, budget plays a role.

• Rental Cost: Smaller utility trailers and tow dollies are generally less expensive to rent than larger utility trailers or full auto transports.
• Fuel Economy: Towing a heavier, larger trailer will significantly impact your tow vehicle’s fuel economy. Factor this into your total cost.

Pro Tips for a Smooth U-Haul Open Trailer Experience

Based on my years of helping people move and my own experiences, these tips are non-negotiable for a safe and successful open trailer rental. Following them can save you immense stress, time, and potential expense.

1. Perform a Pre-Inspection Checklist: Before you even leave the U-Haul lot, do a thorough check.

   • Tires: Inspect tire pressure on both the trailer and your tow vehicle. Check for any visible damage or excessive wear.
   • Lights: Connect the trailer to your vehicle and test all lights: brake lights, turn signals (left and right), and running lights.
   • Hitch Connection: Ensure the hitch ball is securely seated in the coupler and the coupler latch is fully engaged and locked.
   • Safety Chains: Verify that the safety chains are properly crisscrossed under the tongue and securely attached to your tow vehicle’s hitch receiver.
   • Ramp: If applicable, ensure the ramp operates smoothly and latches securely in the stowed position.

2. Master Proper Hitching and Safety Chains: This is the most critical step for safe towing.

   • Always ensure the trailer tongue is fully seated onto the hitch ball. The coupler should lock firmly.
   • The safety chains are a backup in case the hitch fails. Crisscrossing them helps cradle the tongue and prevents it from hitting the ground if it disconnects.
   • Do not let the chains drag on the ground; shorten them if necessary.

3. Optimize Weight Distribution (The 60/40 Rule): This rule is fundamental for preventing trailer sway.

   • Aim to load approximately 60% of your cargo’s weight in the front half of the trailer (closest to your tow vehicle) and 40% in the rear.
   • Heavier items should always go on the bottom, directly over the trailer’s axle.
   • Proper weight distribution creates sufficient "tongue weight" (the downward force the trailer tongue exerts on your hitch), which is essential for stability. Too little tongue weight can cause severe sway.

4. Secure Your Load Effectively: This isn’t just about preventing loss; it’s about preventing dangerous shifting.

   • Use heavy-duty ratchet straps, not just bungee cords or thin rope.
   • Secure items to multiple tie-down points on the trailer.
   • Ensure straps are tight and re-check them after driving a short distance (e.g., 15-20 miles) as items can settle.
   • Use moving blankets or cardboard to protect items from rubbing against each other or the trailer.

5. Drive Safely with a Trailer: Your driving dynamics change significantly when towing.

   • Wider Turns: Trailers cut corners. Always make wider turns to avoid hitting curbs, poles, or other vehicles.
   • Longer Braking Distances: You have more weight to stop. Start braking earlier and more gently.
   • Reduced Speed: Drive slower than you normally would. High speeds increase the risk of sway and make it harder to react to sudden situations.
   • Increased Following Distance: Give yourself much more space between your vehicle and the one in front of you.
   • Check Mirrors Frequently: Be aware of the trailer’s position and surrounding traffic.

Common Mistakes to Avoid When Renting a U-Haul Open Trailer

Even experienced movers can make mistakes. Being aware of these common pitfalls can help you sidestep potential problems.

• Overloading the Trailer: This is perhaps the most dangerous mistake. Exceeding the trailer’s payload capacity or your vehicle’s towing capacity can lead to tire blowouts, brake failure, loss of control, and severe accidents. Always weigh your load if possible or be conservative with your estimates.
• Improper Weight Distribution: As mentioned, too much weight in the back leads to trailer sway, which can be terrifying and extremely difficult to recover from. Too much weight forward can overload your tow vehicle’s rear suspension.
• Neglecting Tie-Downs or Using Inadequate Ones: Loose cargo can shift during transit, causing instability, damaging items, or even flying out and creating a hazard for other drivers. Always use strong, properly rated straps.
• Ignoring Towing Vehicle Limitations: Just because a hitch is installed doesn’t mean your vehicle can safely tow any trailer. Always consult your vehicle’s owner’s manual for specific towing capacities and requirements.
• Not Checking Tire Pressure: Under-inflated trailer tires can overheat, leading to blowouts. Under-inflated tow vehicle tires can affect handling and stability.
• Forgetting to Test Lights: Non-functional trailer lights are not only a safety hazard but also illegal. Always test them before starting your journey and re-check during stops on long trips.
• Attempting to Tow an AWD/RWD Vehicle with a Tow Dolly Without Proper Preparation: This can cause severe damage to the towed vehicle’s drivetrain if not done correctly (e.g., disconnecting the driveshaft). Always use a full auto transport for AWD/RWD vehicles unless specifically advised otherwise by U-Haul with proper instructions.

Making Your U-Haul Open Trailer Reservation

Once you’ve determined the ideal U-Haul open trailer size and confirmed your towing vehicle’s compatibility, making a reservation is straightforward.

• Online Reservations: The U-Haul website is user-friendly and allows you to select your trailer type, pick-up location, dates, and times. You’ll typically need to enter details about your towing vehicle to ensure compatibility.
• Phone Reservations: You can also call your local U-Haul center or their national reservation line. A representative can guide you through the options and help confirm details.
• Information Needed: Be ready to provide your desired trailer size, pick-up and drop-off dates/locations, and details about your tow vehicle (make, model, year, hitch type, and ball size).
• Flexibility: While U-Haul strives to provide the exact equipment and location requested, availability can sometimes vary. Being flexible with your pick-up time or even location by a few miles can often ensure you get the trailer you need.

For the most up-to-date specifications and rental information, always refer to the official U-Haul website.
