Complete Guide To U-Haul Trailer Types And Specifications For 2026
Choosing the correct equipment for a residential or commercial relocation requires a thorough understanding of available towing options. When planning a move in 2026, selecting the right U-Haul trailer prevents mechanical strain on your vehicle, ensures highway safety compliance, and protects your cargo from shifting or weather damage. This comprehensive guide covers all official U-Haul trailer models, dimensional specifications, weight limits, and vehicle compatibility requirements.
Understanding U-Haul Trailer Categories and Towing Mechanics
U-Haul classifies its rental inventory into distinct categories based on size, enclosed protection, and axle configuration. Cargo trailers offer fully sealed, weather-resistant protection for household goods, while utility trailers feature open-deck designs optimized for bulky items, motorcycles, and landscaping equipment. Car trailers and towing dollies cater specifically to motor vehicle transport.
Before booking equipment, you must verify your towing vehicle's Gross Vehicle Weight Rating (GVWR) and hitch capacity. Every hitch is rated by classes (Class I through Class IV), and matching your hitch receiver, ball mount, and trailer coupler size is a strict legal and mechanical requirement. U-Haul utilizes two primary ball sizes across its fleet: a 1-7/8-inch ball for smaller utility configurations and a 2-inch ball for the vast majority of standard cargo and car trailers.
Detailed Breakdown of U-Haul Cargo Trailer Models
Enclosed cargo trailers are the preferred choice for standard moves, protecting mattresses, electronics, and wooden furniture from rain, road debris, and theft. The 2026 lineup features specific models engineered for different volumetric and weight requirements.
- 4x8 Cargo Trailer: This single-axle model provides 162 cubic feet of cargo capacity. It is exceptionally lightweight, making it compatible with smaller crossover SUVs and sedans equipped with a proper hitch.
- 5x8 Cargo Trailer: Offering 196 cubic feet of space, this slightly wider single-axle model accommodates larger boxes and standard furniture items while maintaining a low profile that minimizes wind resistance on the highway.
- 5x10 Cargo Trailer: Stepping up to 283 cubic feet, this model provides additional length for long items like ladders, skis, and extended couches.
- 6x12 Cargo Trailer: The largest enclosed option available, the 6x12 comes in both single-axle and tandem-axle configurations depending on exact regional availability. It delivers an expansive 390 cubic feet of interior space, capable of handling a two-bedroom apartment's worth of boxes and furnishings.
Operational Tip: When loading any enclosed cargo trailer, distribute approximately 60 percent of the total cargo weight toward the front half of the trailer near the coupler, and 40 percent toward the rear. This weight distribution prevents dangerous trailer sway at highway speeds.

Open Utility Trailer Specifications and Applications
Open utility trailers are engineered for hauling irregular shapes, construction materials, and motorized recreational vehicles. They feature heavy-duty steel mesh ramps or fold-down gates for easy loading.
- 4x7 Open Utility Trailer: Ideal for small yard waste runs, furniture pickups, and compact gear. It features a low deck height and simple single-axle maneuverability.
- 5x8 Open Utility Trailer (with Ramp): A versatile mid-size option frequently utilized for moving lawn mowers, building supplies, and bulky items that do not require weather shielding.
- 5x10 Open Utility Trailer (with Ramp): Provides extra deck length for longer items and features high side rails to secure cargo with tie-down straps.
Vehicle Transport Equipment: Trailers and Dollies
Transporting a secondary vehicle requires strict adherence to weight restrictions and drivetrain configurations. U-Haul offers two distinct solutions for vehicle transport.
- Tow Dolly: A front-wheel-lift dolly that hoists the front tires of the towed vehicle off the pavement while the rear tires roll on the ground. This option works well for front-wheel-drive vehicles, though rear-wheel-drive and all-wheel-drive vehicles require the driveshaft to be disconnected or manual modifications to prevent transmission damage.
- Auto Transport Trailer: A full-deck car carrier that lifts all four wheels completely off the ground. Equipped with built-in hydraulic surge brakes and heavy-duty wheel straps, it accommodates most modern sedans, coupes, and light SUVs.

Pros and Cons of Towing a U-Haul Trailer
Evaluating the advantages and limitations of renting a trailer helps determine if this approach aligns with your moving strategy.
Advantages
- Cost-Effective: Renting a trailer is significantly more affordable than hiring a full-service moving company or renting a large commercial box truck.
- Keep Your Vehicle: You retain the comfort and familiarity of driving your own personal tow vehicle during the move.
- Uncoupling Flexibility: Once you arrive at your destination, you can unhook enclosed or utility trailers from your vehicle, allowing you to run errands without packing up your entire setup.
Limitations
- Towing Dynamics: Driving with a trailer increases stopping distances, requires wider turns, and introduces reversing challenges.
- Vehicle Limitations: Not all vehicles are mechanically cleared for towing. Small cars, hybrids, and vehicles lacking a proper structural hitch cannot legally or safely pull U-Haul equipment.
- Speed Restrictions: Many states and rental agreements mandate lower speed limits when towing trailers, which can increase overall travel time.
Step-by-Step Guide to Reserving and Hitching Your U-Haul Trailer
Securing and attaching a rental trailer requires adherence to safety protocols and regulatory standards.
- Verify Vehicle Compatibility: Check your vehicle owner's manual for towing capacity limits. Schedule a professional hitch inspection at a certified U-Haul center to ensure your vehicle has a Class II or higher hitch receiver installed.
- Book Online: Select your preferred trailer model, pickup location, and rental dates through the official reservation platform. Ensure you select the correct electrical light plug adapter (4-way flat is standard).
- Inspect the Equipment: Upon arrival, examine the tires for adequate tread depth, test all running lights, brake lights, and turn signals, and verify the safety chains and coupler latch operate smoothly.
- Load Strategically: Center your cargo and place heavier items over the axle or slightly forward to maintain tongue weight. Secure all loose items with heavy-duty ratchet straps.
- Cross Safety Chains: Cross the safety chains in an "X" pattern underneath the tongue before attaching them to the tow vehicle frame. This prevents the trailer tongue from dropping to the pavement if the primary coupler disengages.
Frequently Asked Questions About U-Haul Trailers
What size hitch ball do I need for a U-Haul trailer?
Most U-Haul trailers require either a 1-7/8-inch or a 2-inch hitch ball. Larger trailers, such as the 6x12 cargo trailer and the auto transport, strictly require a 2-inch ball.
Does my personal vehicle need special wiring for the trailer lights?
Yes, your towing vehicle must be equipped with a functional lighting hookup, typically a 4-way flat connector, to power the trailer's brake lights, running lights, and turn signals. U-Haul service centers can install universal wiring packages if your vehicle lacks them.
Can any vehicle tow a U-Haul cargo trailer?
No, U-Haul restricts trailer rentals based on the manufacturer's towing specifications for your specific year, make, and model. Vehicles without a rated tow hitch, certain sports cars, and small compact hatchbacks may be denied rentals for safety reasons.
Are U-Haul trailers equipped with brakes?
Enclosed cargo trailers and utility trailers under specific weight thresholds rely on the towing vehicle's braking system. However, the heavy-duty Auto Transport trailer features built-in hydraulic surge brakes that automatically engage when your tow vehicle slows down.
How fast can I drive while towing a U-Haul trailer?
You should always obey local and state highway speed limits. Many jurisdictions enforce a maximum speed limit of 55 to 65 mph for vehicles towing trailers, and driving defensively with increased following distances is essential for safety.
Conclusion and Next Steps
Choosing the right U-Haul trailer model ensures your belongings remain secure and your towing vehicle operates within safe mechanical limits. Review your cargo volume, check your vehicle's towing capacity, and reserve your equipment in advance to streamline your upcoming relocation.
