A Comprehensive Guide To The Different Types Of U-Haul Trailers
When planning a move or a large equipment transport project, selecting the right towing equipment is the most critical decision you will make. U-Haul remains the industry standard for DIY moving because of its massive inventory of specialized trailers designed for various cargo capacities and vehicle types. Understanding the distinct differences between these units is essential for ensuring both safety on the road and the protection of your belongings.
Choosing the incorrect trailer can lead to mechanical strain on your tow vehicle, dangerous trailer sway, or legal liabilities if the weight exceeds your vehicle’s rated towing capacity. This guide breaks down the primary options available and provides technical insights into how to choose the right one for your specific needs.
Cargo Trailers: The Gold Standard for Household Moves
Cargo trailers are the most versatile option in the U-Haul fleet. Designed as enclosed, weather-resistant boxes, they are ideal for transporting furniture, boxes, and sensitive equipment that cannot be exposed to the elements. These trailers come in two primary sizes: 4’x8’ and 5’x10’.
The 4’x8’ cargo trailer is designed for small-scale moves, such as relocating a studio apartment or moving specific pieces of furniture. It is compact, easy to maneuver in reverse, and can be towed by almost any vehicle with a hitch. Because of its aerodynamic profile and lower weight, it is a favorite for those who are new to towing.
The 5’x10’ cargo trailer offers significantly more vertical space and floor area, making it the preferred choice for one-bedroom apartment moves. It features a flat floor, which allows for easier stacking of boxes. Both sizes are equipped with rub rails for securing loads with straps, ensuring your items remain stationary during transit. Always ensure your load is balanced over the trailer axle to prevent fishtailing.
Utility Trailers: Open-Air Versatility
Utility trailers are open-top, flat-bed units designed for items that do not require climate protection or are simply too large/awkward for an enclosed trailer. U-Haul offers several sizes, typically ranging from 4’x7’ to 6’x12’. These are widely used for hauling landscaping materials, motorcycles, ATVs, or debris removal.
The 4’x7’ utility trailer is the most compact open trailer, perfect for quick trips to the dump or picking up mulch. The 5’x8’ and 5’x9’ variants include features like drop-down tailgates that act as ramps, simplifying the process of loading heavy items or rolling equipment. The 6’x12’ utility trailer is the heavy-duty option in this category, often featuring higher sides to prevent cargo from spilling out during transport.
One distinct advantage of utility trailers is the ease of loading. Without walls, you have a 360-degree view of your cargo while loading, and there is no door to latch or seal. However, you must be diligent about using heavy-duty ratchet straps and cargo nets to secure your items, as they are exposed to wind and road debris.

Tow Dollies and Auto Transports: Moving Your Vehicle
When you need to move your primary vehicle alongside your belongings, U-Haul provides two distinct solutions: the Tow Dolly and the Auto Transport (car carrier). Choosing between them depends entirely on the type of vehicle you are towing and your comfort level with towing configurations.
A Tow Dolly is a two-wheel trailer that lifts the front two wheels of the car off the ground, while the rear wheels remain on the road. This is generally more affordable and compatible with a wider variety of front-wheel-drive vehicles. However, it requires you to disconnect the driveshaft if you are towing a rear-wheel-drive car, which can be mechanically complex.
The Auto Transport is a full four-wheel trailer that lifts the entire vehicle off the ground. This is the safer and more professional option for long-distance moves. It prevents wear and tear on the towed vehicle's tires and drivetrain. Most modern vehicles, including SUVs and trucks, are better suited for an auto transport than a tow dolly due to weight distribution and clearance requirements.

How to Get Started with Your Rental
The process of renting a U-Haul trailer is streamlined but requires strict attention to the compatibility between your vehicle and the equipment. Before booking, check your vehicle’s owner’s manual for its "Maximum Towing Capacity." U-Haul’s online reservation system will cross-reference this information. If your vehicle lacks the necessary hitch or wiring, the reservation will be flagged.
- Verify Hitch Compatibility: Ensure your vehicle has a receiver hitch that matches the size required by the trailer (usually a 2-inch ball).
- Online Reservation: Use the official U-Haul website to input your pickup and drop-off locations. Booking online ensures that the specific trailer type you need is reserved at your chosen location.
- Inspection: During pickup, perform a walk-around. Check the tires for dry rot, ensure the lights function correctly, and verify the safety chains are present and free of kinks.
- Loading Strategy: Always distribute 60% of the cargo weight in front of the axle. This prevents the "sway" phenomenon that causes accidents.
Safety and Operational Trends
Safety is the primary concern when towing. U-Haul trailers are designed with low centers of gravity, but they are still susceptible to "trailer sway" at high speeds. To mitigate this, always maintain a speed limit below 55 mph while towing, regardless of the posted road speed. Increased following distance is mandatory; you should aim for at least 6–8 seconds of space between you and the vehicle in front to account for the increased stopping distance.
Another significant operational trend is the shift toward "in-town" vs. "one-way" rentals. One-way rentals are generally more expensive because they require U-Haul to relocate the equipment, whereas in-town rentals require the customer to return the unit to the originating facility. If you are doing a long-distance move, verify the drop-off location's availability in advance to avoid "drop-off" fees.
Frequently Asked Questions
Can I tow a U-Haul trailer with an SUV?
Yes, most mid-size and full-size SUVs are capable of towing U-Haul trailers. However, you must ensure your SUV meets the minimum weight requirements and has a proper receiver hitch installed.
Do I need a special driver's license?
No, all U-Haul trailers are designed to be towed with a standard Class C driver's license. No commercial license is required for personal household moves.
What happens if I have a flat tire on the road?
U-Haul includes 24/7 roadside assistance with every trailer rental. If you experience a mechanical failure, you can contact their support line, and they will dispatch a service technician to your location.
Are U-Haul trailers waterproof?
The cargo trailers are weather-resistant and designed to protect items from rain and road spray. However, they are not hermetically sealed, so it is best to wrap delicate electronics or fabrics in plastic.
Can I tow a trailer with a rental truck?
Yes, you can rent a U-Haul cargo van or pickup truck to tow a utility or cargo trailer, provided the combined weight is within the rental vehicle's towing limit.
