More Details on Our Top Picks
Let’s Go Aero GearSpace Slideout Hitch Cargo Carrier – Dark Gray
This cargo carrier stands out for its sturdy construction and generous size, providing a reliable platform that supports up to 150 pounds, making it ideal for outdoor gear and travel essentials. Compared with larger capacity options like the Mockins 60″ x 19.3″ tray, it offers easier handling and simpler installation, though it is still quite bulky and heavy. Its slideout feature adds convenience for accessing stored items without detaching the entire unit. However, handling this carrier requires some effort due to its weight, and its limited color options might not suit all vehicle aesthetics. Overall, this pick makes the most sense for users seeking a durable, straightforward cargo solution that can be easily attached and removed for moderate loads.
Pros:- Sturdy construction with high weight capacity
- Easy to attach to vehicle hitch
- Provides additional cargo space for trips
Cons:- Heavy and bulky to handle
- Limited color options
- May require installation tools or expertise
Best for: Owners who want a durable, easy-to-attach cargo carrier for outdoor gear and moderate loads
Not ideal for: Users needing ultra-lightweight carriers or extensive customization options
- Brand:Let’s Go Aero
- Model Number:HGK819
- Weight Capacity:150 Pounds
- Dimensions:68 x 33 x 40 inches
- Item Package Quantity:1
- UPC:830881000819
Our verdict“This carrier is best suited for outdoor enthusiasts needing a reliable, mid-capacity hitch solution that balances durability and ease of use.”
Mockins 60″ x 19.3″ x 2.5″ Heavy Duty Trailer Hitch Tray with 750 lbs Capacity
Compared with smaller carriers like the CURT 18113, the Mockins tray offers an enormous 750-pound capacity, making it perfect for hauling heavy equipment or multiple bulky items. Its folding design allows for easier storage when not in use, and included straps, reflectors, and stabilizers enhance safety and security during transport. The tradeoff is its weight—at 57 pounds, it can be cumbersome to handle, especially for those with limited strength or mobility. Assembly upon delivery can also be time-consuming. This product is ideal for those with 2-inch hitch receivers who need to carry substantial loads without sacrificing safety features.
Pros:- Supports up to 750 lbs for heavy loads
- Folding for compact storage
- Includes safety straps, reflectors, and stabilizer
Cons:- Heavy weight makes handling difficult
- Assembly required upon delivery
- Limited to 2-inch hitch receivers
Best for: Heavy-duty users needing to transport bulky or heavy items on a regular basis
Not ideal for: Casual users or those with limited strength who prefer lightweight, quick-install carriers
- Dimensions:60″ x 19.3″ x 2.5″
- Capacity:750 lbs
- Hitch Size:2 inches
- Weight:57 lbs
- Material:Rust and corrosion resistant
Our verdict“This tray is best suited for users who require maximum load capacity and are comfortable handling heavier equipment for secure hauling.”
Thule Arcos Cargo Box
The Thule Arcos Cargo Box offers up to 14 cubic feet of storage with an aerodynamic profile designed to minimize fuel consumption, making it ideal for long trips. Its SlideLock system ensures secure locking and easy access, and its low-profile design simplifies loading and unloading. However, it requires the Thule Arcos Platform, which adds to the overall cost and limits compatibility with other systems. Compared to the more versatile cargo trays, this box excels in reducing wind resistance and fuel use but is less flexible for different vehicle setups. This makes it an excellent choice for users prioritizing aerodynamics and weather protection over capacity or universal fit.
Pros:- Provides ample extra storage space
- Aerodynamic design reduces fuel impact
- Easy to load and unload
Cons:- Requires Thule Arcos Platform
- Limited compatibility outside Thule system
- Less capacity compared to large trays
Best for: Travelers needing secure, weatherproof storage with minimal impact on fuel economy
Not ideal for: Owners seeking a universal, no-setup cargo solution or those with non-Thule systems
- Capacity:14 cu ft
- Compatibility:Requires Thule Arcos Platform
- Design:Aerodynamic
- Locking System:SlideLock
Our verdict“This cargo box is ideal for users who want aerodynamic, weather-resistant storage that integrates seamlessly with Thule systems for long-distance travel.”
Mockins 50″x24″x7″ Aluminum Hitch Cargo Carrier & 25 Cu Ft Cargo Bag
This lightweight aluminum carrier supports up to 500 pounds and includes a waterproof 25 cubic foot cargo bag, making it suitable for all-weather, heavy-duty hauling. Its corrosion-resistant design and included security features like locks and straps make it a durable and secure option, especially for users with trailers or SUVs equipped with 2″ receivers. Compared to solid metal trays, the aluminum frame reduces weight while maintaining strength, though it might require verification of vehicle compatibility with spare tires and other accessories. The added cargo bag provides weatherproof storage, but the setup process can be more involved. This carrier is best for those needing large, secure, all-weather cargo capacity without excessive weight.
Pros:- Durable, corrosion-resistant aluminum construction
- Supports up to 500 lbs
- Includes waterproof cargo bag and security locks
Cons:- May require vehicle compatibility verification
- Complex setup for some users
- Heavy-duty design may be challenging for some
Best for: Users seeking weatherproof, heavy-duty hauling with extra cargo capacity
Not ideal for: Light-duty users or those with limited vehicle compatibility checks
- Dimensions:50″x24″x7″
- Cargo Capacity:500 lbs
- Cargo Volume:25 Cu Ft
- Material:Aluminum
- Waterproof Cargo Bag:Yes
- Warranty:10 years
Our verdict“This carrier is best suited for users needing robust, weatherproof cargo transport with ample capacity and security features.”
CURT 18113 49 x 22-1/2-Inch Black Aluminum Hitch Cargo Carrier
The CURT 18113 is a lightweight yet sturdy option, weighing only 25 pounds but supporting up to 500 pounds, thanks to its welded aluminum construction. Its 4-inch high sides help contain cargo and prevent shifting, while its simple design makes installation straightforward. Compared to bulkier steel trays, this carrier offers easier handling and a cleaner look. However, its high sides may limit some types of cargo, and it lacks an included lock, so securing items requires additional accessories. This product is an excellent choice for users who prioritize ease of handling and secure attachment without sacrificing load capacity.
Pros:- Lightweight and easy to handle
- Supports up to 500 lbs
- Corrosion-resistant for durability
Cons:- Limited to 2-inch hitch receivers
- No included lock for security
- High sides may restrict some cargo types
Best for: Owners who need a lightweight, easy-to-install cargo carrier with good security options
Not ideal for: Those requiring extensive cargo volume or built-in security locks
- Weight:25 pounds
- Dimensions:49 x 22.5 inches
- Capacity:500 lbs
- Hitch Size:2-inch x 2-inch
- Side Walls:4 inches high
Our verdict“This carrier is perfect for those looking for a durable, lightweight option that’s quick to install and supports substantial loads but doesn’t include built-in security features.”
Let’s Go Aero GearSpace® Slideout Hitch Cargo Carrier – Light Gray
The Let’s Go Aero GearSpace® Slideout Hitch Cargo Carrier stands out for its impressive 34 cubic feet of space and a substantial 300 lbs load capacity, making it ideal for bulky luggage, bikes, or outdoor gear. Its slide-out mechanism offers a significant advantage over fixed carriers like the UWS EC20261, providing easier access to your vehicle’s rear hatch without unloading everything. However, this feature adds weight and complexity, and the carrier requires freight shipping, which can complicate delivery. Compared to smaller, simpler models, this option is less suitable for light-duty or quick trips but excels in scenarios demanding large-volume storage. Its weatherproof, lockable capsule keeps gear secure, making it perfect for long trips or outdoor adventures. The bulky design and heavier weight may pose challenges for installation and handling, especially on smaller vehicles.
Pros:- Large storage capacity ideal for bulky gear and multiple items
- Slide-out feature allows easy rear hatch access without unloading
- Weather-proof, secure locking capsule keeps contents protected
Cons:- Heavy and bulky, making installation and handling challenging
- Requires freight shipping and delivery verification, adding complexity
Best for: Owners needing significant storage space with rear hatch access, such as long-distance travelers or outdoor enthusiasts carrying bikes and gear.
Not ideal for: Casual users or those with small vehicles seeking a lightweight, easy-to-install carrier for occasional trips.
- Load Capacity:300 lbs
- Storage Volume:34 cubic feet
- Pod Dimensions:63in L x 28in D x 40in H
- Hitch Size:2 inches
- Maximum Load on Hitch:350 lbs
Our verdict“This carrier suits those who prioritize maximum storage and rear access over ease of handling or quick setup.”
Buyers Products Poly Hitch Mounted Cargo Carrier, 23x51x26, Includes Polyethylene Chest, Steel Frame, 5/8in. Hitch Pin
The Buyers Products Poly Hitch Mounted Cargo Carrier offers a practical solution for outdoor and utility storage, combining a durable polyethylene chest with a sturdy steel frame. Its 17 cubic feet of waterproof, lockable space makes it a strong contender against the Let’s Go Aero GearSpace® when the focus is on weather resistance and security. While it’s easier to assemble and fits standard 2-inch receivers, it’s less suited for hauling very large or bulky gear due to its smaller capacity. The padlocks are sold separately, which could be inconvenient for users seeking an all-in-one lockable solution. Compared to the aluminum UWS, this model provides a more affordable, weatherproof option but sacrifices some durability and security features. Its lighter weight and straightforward design make it appealing for quick, secure outdoor storage.
Pros:- Waterproof and lockable polyethylene chest enhances security and weather resistance
- Easy to assemble with pre-drilled steel frame
- Fits standard 2-inch hitch receivers for wide compatibility
Cons:- Padlocks sold separately, adding extra cost
- Heavy when fully loaded, which could impact handling and vehicle fuel efficiency
Best for: Outdoor workers or travelers needing waterproof, lockable storage for tools, gear, or valuables without the bulk of large volume carriers.
Not ideal for: Heavy-duty users requiring maximum capacity or those carrying oversized or multiple bulky items regularly.
- Dimensions:23x51x26 inches
- Material:High-density polyethylene, steel
- Capacity:200 lbs
- Hitch Size:2 inches
- Includes:Polyethylene chest, steel frame, 5/8 inch hitch pin
Our verdict“This carrier is best suited for users who need secure, waterproof outdoor storage without the hassle of handling larger, heavier units.”
UWS EC20261 48-Inch Heavy-Wall Aluminum Cargo Carrier Box, RigidCore Lid, Silver
The UWS EC20261 is designed for durability, featuring heavy-wall aluminum construction combined with RigidCore lid technology that maximizes security and strength. Compared with the Buyers Products polyethylene chest, this aluminum box offers increased longevity and resistance to the elements, making it ideal for frequent or long-term outdoor storage. Its reinforced lid prevents warping and breakage, though it’s primarily intended for use with specific hitch carriers, which could limit compatibility. The weight of the thick aluminum makes it more cumbersome to handle, especially for users with limited strength or smaller vehicles. While it doesn’t specify lock security features in detail, the sturdy construction naturally discourages theft, but additional locks might be needed for enhanced security.
Pros:- Heavy-wall aluminum offers exceptional durability and corrosion resistance
- RigidCore lid provides maximum security and strength
- Versatile application for trucks, shops, or permanent storage
Cons:- Designed mainly for specific hitch models, limiting flexibility
- Heavy weight due to thick aluminum can complicate handling and installation
- Limited info on lock security features, requiring additional measures for theft prevention
Best for: Frequent outdoor users or professionals seeking a long-lasting, secure cargo box for trucks, shops, or heavy-duty storage needs.
Not ideal for: Casual users or those looking for a lightweight, easy-to-mount option for occasional use, as it may be heavy and limited in compatibility.
- Size:48 inches
- Material:Aluminum
- Wall Thickness:0.058 inch
- Lid Technology:RigidCore
- Handle Material:Stainless steel
Our verdict“This aluminum cargo box suits those needing a durable, long-lasting storage solution for frequent outdoor or professional use, despite handling challenges.”

Factors to Consider When Choosing Lockable Hitch Cargo Carrier Boxes
When selecting a lockable hitch cargo carrier box, it’s important to think beyond just capacity and price. Consider how the material affects weight and durability, whether the locking system offers real security, and if the size matches your typical cargo. Compatibility with your vehicle’s hitch size and ease of installation can save time and frustration. Weatherproofing and corrosion resistance are essential for longevity, especially if you’ll use the carrier in various climates. Balancing these factors helps ensure you choose a product that fits your specific needs without unnecessary compromises.Material and Construction
Material choice impacts weight, durability, and resistance to the elements. Aluminum carriers are lighter and naturally resistant to rust, making them suitable for frequent use and variable weather. Steel options tend to be more robust but are heavier and may require additional maintenance. Consider whether the carrier’s construction is reinforced enough to withstand road debris and rough handling, especially for long trips or off-road use. A well-built box made from high-quality materials typically offers better security and longevity.
Locking Mechanisms and Security
The core purpose of these carriers is to secure your gear, so a reliable lock system is essential. Look for models with integrated keyed locks or combination locks that resist tampering. Some budget options may only have basic latches, which are easier to bypass, so weigh the importance of security against your budget. A good lock not only deters theft but also keeps weather and debris out, protecting your cargo from damage. Consider whether the lock is easy to operate with gloves or in low-light conditions.
Capacity and Size
Assess your typical cargo volume to choose an appropriately sized carrier. Larger boxes provide more space but can add significant weight and may be harder to install or remove. Smaller carriers are more manageable but limit what you can carry. Keep in mind your vehicle’s hitch weight limits and whether the carrier’s size will interfere with rear visibility or access to the trunk. Matching capacity to your actual needs prevents overpaying for unused space or struggling with an overly large box.
Installation and Compatibility
Ease of installation varies among models, with some requiring simple hand tools and others needing more effort. Check the hitch size compatibility—most carriers fit 2-inch receivers, but a few can adapt to different sizes. Consider whether the carrier includes necessary mounting hardware and if it can be easily removed or transferred between vehicles. Proper installation is crucial for safety; a poorly mounted carrier can detach during transit, risking damage or accidents.
Weatherproofing and Maintenance
Weatherproofing features like sealed lids, weather-resistant materials, and corrosion-resistant coatings extend the life of your carrier. If you plan to use the carrier in rain, snow, or humid environments, prioritize models with effective sealing and rust-resistant finishes. Regular maintenance, such as cleaning and occasional lubrication of locks, can keep the carrier functioning smoothly. Investing in a weatherproof model may cost more initially but saves money over time by preventing damage and corrosion.
Frequently Asked Questions
How secure are the locks on these cargo carriers?
The security of the locks varies significantly across models. Premium carriers often feature keyed locks with tamper-resistant designs, making theft more difficult. Budget options may have basic latches that can be bypassed more easily. When security is a priority, look for models that include high-quality locks and consider adding a cable lock for additional protection. Remember, no lock is entirely theft-proof, but a strong lock discourages casual theft and unauthorized access.
Will a lockable cargo box fit my vehicle’s hitch receiver?
Most lockable hitch cargo carriers are designed for standard 2-inch receivers, which are common on trucks and SUVs. Some models include adapters or are compatible with different hitch sizes, but always verify your vehicle’s hitch dimensions before purchasing. Ensuring compatibility prevents installation issues and maintains safety during transit. Check the product specifications carefully, especially if your vehicle has a unique hitch configuration or if you plan to switch between multiple vehicles.
Are lockable hitch cargo boxes waterproof?
Many models include weather-resistant features like sealed lids and corrosion-resistant materials, but the level of waterproofing can vary. Look for carriers with gasketed or rubberized seals to keep out rain, snow, and dust. Regular maintenance, such as cleaning the seals and lubricating locks, can enhance waterproof performance. Keep in mind that no carrier is completely impervious to water if subjected to prolonged heavy rain or submersion, so choose a model with proven weatherproofing if your trips involve harsh conditions.
How much weight can these cargo carriers hold?
Weight capacity ranges from around 500 to over 750 pounds, depending on the model. It’s important to stay within your vehicle’s hitch weight limit as well as the carrier’s maximum load to avoid safety issues. Heavier loads may also impact fuel efficiency and handling. Always check the manufacturer’s specifications and consider how much gear you typically carry to select a carrier that balances capacity with ease of installation and use.
Can I install and remove these cargo carriers by myself?
Most models are designed for straightforward installation and removal, often requiring only basic tools. Carriers with a simple clamp or bolt-on system can typically be installed or removed by a single person, though heavier or larger boxes may need assistance. Consider if the carrier has quick-release features or foldable designs to simplify handling. Properly securing the carrier during installation is essential for safety and to prevent damage during transit.
Conclusion
For those seeking the best overall combination of security, durability, and ease of use, the Thule Arcos Cargo Box stands out, especially for frequent travelers and long trips. Budget-conscious buyers will appreciate the Mockins Heavy Duty Trailer Hitch Tray for its affordability and capacity. If you prioritize lightweight construction and corrosion resistance, the UWS Heavy-Wall Aluminum Cargo Carrier makes a strong case. Beginners or occasional users should opt for models with straightforward installation, like the Buyers Products Steel Frame Carrier. For users with specific needs, such as off-road or extreme weather, considering specialized features like reinforced construction or enhanced weatherproofing can make a significant difference. Ultimately, matching the product to your specific cargo, vehicle, and security needs will ensure a satisfying purchase.
