More Details on Our Top Picks
StowAway Max Hitch Cargo Box with Swingaway Frame
The StowAway Max stands out for its generous 16 cubic feet of enclosed storage, making it ideal for families or adventurers with significant gear. Its swingaway frame offers unmatched rear access compared to traditional fixed carriers like the MaxxHaul 70108, eliminating the need to unload cargo to access items behind the carrier. Weather-resistant construction and secure locking enhance safety during long trips, while LED lighting adds an extra layer of security. The main tradeoff is its weight, which can make installation challenging without assistance, and the limited color options may not suit all vehicles. This pick works well for users prioritizing security, weatherproofing, and full rear access, even if they’re okay with a heavier setup.
Pros:- Large 16 cubic feet of enclosed storage
- Swingaway frame enables full rear access
- Weather-resistant, impact-resistant polymer construction
- Secure locking system with LED safety lights
Cons:- Heavy weight may require assistance to install

Our verdict“This carrier suits users who need maximum security, weatherproofing, and full rear access despite its heavier build.”
CURT 18150 Cargo Basket Hitch Trailer Hitch Cargo Carrier
The CURT 18150 excels in supporting heavy loads with a 500 lbs capacity, making it ideal for hauling larger, bulkier items like furniture or multiple bags. Compared to the MaxxHaul 70108, its high sides—standing 6 inches tall—offer added security for loose or taller items, while its mesh platform simplifies cleanup after trips. Made from rugged tubular steel, it’s built for durability, but its weight and size make solo installation tricky, especially on smaller vehicles. Meanwhile, its 2-inch receiver fit limits compatibility to certain vehicles. This carrier is best suited for users needing maximum load support and security for bulky cargo, though it sacrifices some ease of installation.
Pros:- Supports up to 500 lbs of cargo
- High 6-inch sides keep items secure
- Heavy-duty tubular steel construction
- Mesh platform simplifies cleaning
Cons:- Heavy and difficult to install alone
- Limited to 2-inch receiver hitches
Best for: Heavy-duty users needing secure, high-capacity cargo support for large or tall items during extended trips.
Not ideal for: Owners with smaller vehicles or those seeking lightweight, quick-to-mount options for occasional use.
- Capacity:500 lbs
- Dimensions:59-1/2 x 20-1/4 x 5-1/2 inches
- Material:Heavy-duty tubular steel
- Sides Height:6 inches
Our verdict“Ideal for users prioritizing maximum load capacity and cargo security over ease of installation.”
Elevate Outdoor Hitch Cargo Carrier Tray Aluminum 550 lb Capacity
The Elevate Outdoor Aluminum Carrier makes a compelling case for those needing a lightweight yet strong hauling option, supporting up to 550 lbs with minimal added weight. Its slatted aluminum design promotes drainage, making it suitable for wet or muddy conditions—an advantage over steel carriers like the MaxxHaul 70108. The large tray and multiple tie-down points offer versatility for hauling diverse loads, but its compatibility depends on your vehicle’s mounting setup, and the lack of detailed weather resistance info could be a concern for prolonged exposure. This model is best for users who want a durable, rust-resistant carrier that doesn’t add much weight to their vehicle.
Pros:- Lightweight aluminum construction supports up to 550 lbs
- Slatted design enhances drainage and debris removal
- Ample tie-down points for securing cargo
- Rust-resistant and durable
Cons:- May require vehicle compatibility checks
- Limited info on weather resistance
Best for: Owners of vehicles needing a lightweight, high-capacity carrier for wet or muddy conditions, like lawn or outdoor equipment transport.
Not ideal for: Users with very specific hardware or those seeking detailed weather resistance data for long-term outdoor use.
- Material:Aluminum
- Weight Capacity:550 lbs
- Tray Dimensions:49.125″ L x 22.625″ W
Our verdict“Best suited for those needing a lightweight, durable carrier capable of handling wet or muddy loads with ease.”
CURT 18100 Tray-Style Trailer Hitch Cargo Carrier
The CURT 18100 offers a folding tray design that helps save space when not in use, making it ideal for users with limited storage options. Its 60 x 19-inch aluminum platform provides ample space for cargo, and the mesh base supports easy cleanup, similar to the Elevate model but with the added convenience of foldability. While its lightweight aluminum construction facilitates quick installation, it might not withstand the same level of heavy-duty use as steel carriers like the CURT 18150. This carrier is best for owners who value easy storage and moderate capacity, but it’s less suited for very heavy or rough use.
Pros:- Folding design for compact storage
- Lightweight aluminum construction
- Mesh base simplifies cleaning
- Increases vehicle cargo capacity
Cons:- Limited to 2-inch receiver hitches
- Potentially less durable than steel options
Best for: Travelers needing a portable, space-saving carrier for moderate loads and easy storage.
Not ideal for: Heavy-duty users or those hauling very bulky or tall cargo regularly who require maximum support and security.
- Capacity:500 lbs
- Dimensions:60 x 19 inches
- Receiver Size:2 inches
- Material:Lightweight aluminum
Our verdict“Ideal for users who need a foldable, easy-to-store carrier for moderate loads and space efficiency.”
MaxxHaul 70108 Aluminum Cargo Carrier with High Side Rails
The MaxxHaul 70108 emphasizes high side rails and a straightforward design, making it a flexible option for hauling bulky or taller items. Its 49 x 22.5-inch aluminum platform supports 500 lbs, similar to the CURT 18113, but its high side rails help contain loose cargo more securely, especially when the vehicle is on uneven terrain. Its aluminum build ensures rust resistance and easier handling, but the 500-lb weight limit can be restrictive for very heavy loads, and taller items may be harder to load over the high rails. This carrier suits users who need versatility in cargo height and secure containment, although it’s less ideal for very heavy-duty applications.
Pros:- High side rails for taller cargo
- Lightweight, rust-resistant aluminum construction
- Supports up to 500 lbs
- Easy to install and maintain
Cons:- Limited to 500-lb capacity
- High sides may complicate loading very tall items
Best for: Outdoor or RV users needing high sides for taller or loose cargo with easy handling and rust resistance.
Not ideal for: Those with very heavy or bulky loads exceeding 500 lbs or who prefer a lower-profile carrier.
- Material:Aluminum
- Load Capacity:500 lbs
- Dimensions:49 x 22.5 inches
Our verdict“Best for users seeking high sides for taller cargo and a durable, rust-resistant platform.”
CURT 18113 49 x 22.5-Inch Black Aluminum Hitch Cargo Carrier, 500 lbs Capacity, 2-in Fixed Shank
The CURT 18113 stands out as a lightweight yet robust option for those who need a durable cargo solution without adding significant weight to their vehicle. Weighing only 25 pounds, it offers an impressive 500-pound weight capacity, making it suitable for hauling heavy gear or equipment securely. Compared with the MaxxHaul Aluminum Cargo Carrier, which is similar in weight and capacity, the CURT’s aluminum construction provides superior corrosion resistance and a sleek black powder coat finish, ensuring longevity in all weather conditions. However, its fixed 2-inch shank limits versatility, and it lacks foldable features found in other models like the StowAway Max Hitch Cargo Box, which offers easier storage when not in use. This pick makes the most sense for users prioritizing a lightweight, corrosion-resistant carrier that can handle substantial loads but don’t need the convenience of folding or collapsing features.
Pros:- Lightweight at only 25 pounds, easy to handle and install
- Supports up to 500 pounds, suitable for heavy loads
- Aluminum construction offers excellent corrosion resistance
- High walls (4 inches) help secure cargo during transit
Cons:- Limited to 2-inch hitch receivers, reducing compatibility
- No foldable or collapsible feature for easier storage
- Lacks integrated locks or security features
Best for: Travelers who need a strong, corrosion-resistant carrier capable of hauling heavy equipment without adding extra weight to their vehicle.
Not ideal for: Casual users who prefer a foldable or easily stowable cargo carrier, or those with non-2-inch hitch receivers seeking more versatility.
- Weight:25 pounds
- Dimensions:49 x 22.5 inches
- Capacity:500 lbs
- Hitch Size:2 inches x 2 inches
- Wall Height:4 inches
- Material:Aluminum
- Finish:Black powder coat
Our verdict“This carrier is ideal for users needing a lightweight, high-capacity aluminum option that resists corrosion but don’t require foldability or advanced security features.”

Factors to Consider When Choosing Rated Lockable Hitch Cargo Carrier Boxes
Choosing the right lockable hitch cargo carrier box involves more than just capacity. It’s essential to consider factors like security, material, size, and ease of use to match your specific needs. This guide explores key considerations to help you avoid common mistakes and select a carrier that offers durability, convenience, and value.Security and Locking Features
Security is a top priority for lockable cargo boxes. Look for models with sturdy locking mechanisms that resist tampering. Some carriers feature integrated locks, while others require aftermarket solutions. A lock alone isn’t enough—consider how well the lock mechanism is protected from weather and corrosion. Investing in a carrier with reliable security features helps prevent theft of your cargo during stops or overnight stays.
Material and Durability
The material impacts both weight and longevity. Aluminum carriers are lighter and more resistant to rust, ideal for frequent travelers or those in humid environments. Steel options are typically more rugged, offering enhanced durability for heavy loads or rough conditions but are heavier and may require more maintenance. Choosing the right material depends on your climate, frequency of use, and capacity needs.
Size and Capacity
Match the carrier size to your vehicle’s receiver and cargo. Larger boxes provide more storage but can be more cumbersome to handle and install. Capacity ratings, usually around 500-550 lbs, determine how much weight your carrier can support safely. Overloading beyond the rated capacity risks damage and safety concerns, so always balance size with your actual cargo needs.
Ease of Installation and Access
Ease of installation varies; some carriers attach quickly to standard 2-inch receivers, while others require more tools or steps. Swingaway and tilt features significantly improve access, especially when the carrier is loaded. Consider how often you’ll need to access your cargo and whether additional features justify a higher price or increased complexity.
Budget and Overall Value
While premium models offer advanced security and features, budget-friendly options can still provide reliable protection for moderate use. Balance your budget against the features most important for your needs. Remember, a more expensive carrier isn’t always better if it doesn’t fit your specific requirements, but investing in quality can save money long-term through durability and security.
Frequently Asked Questions
Are lockable hitch cargo carriers waterproof?
Most lockable hitch cargo carriers are designed with weather-resistant materials and seals to protect your cargo from rain and snow. However, the level of waterproofing varies—some models have gasket seals and sealed locks, while others may only resist moisture. For complete protection, consider carriers with integrated weatherproof features or add waterproof bags for sensitive items.
Can I install a lockable cargo box on any vehicle?
Installation depends primarily on your vehicle’s receiver size and available clearance. Most carriers are compatible with standard 2-inch receivers, common on trucks and SUVs. However, access and stability can be affected by your vehicle’s design and bumper configuration. Always check the carrier’s specifications against your vehicle’s receiver and available space before purchasing.
Is a lockable cargo carrier worth the extra cost?
If you frequently travel with valuable or sensitive cargo, a lockable carrier adds significant security, making the extra investment worthwhile. For occasional use, a basic carrier without locks might suffice, but it offers less protection against theft. Weigh the added safety and convenience against your budget to determine if the upgrade aligns with your travel habits.
How do I maintain and clean my lockable cargo box?
Regular maintenance involves cleaning with mild soap and water, especially after exposure to dirt and road grime. Lubricate locks periodically with silicone spray to keep them operating smoothly. For metal carriers, inspect for rust or corrosion and address it promptly with touch-up paint or rust inhibitors. Proper care extends the lifespan and maintains security features effectively.
What is the typical lifespan of a lockable hitch cargo box?
The lifespan varies based on material, usage, and maintenance. Aluminum models tend to last longer due to corrosion resistance, often exceeding a decade with proper care. Steel carriers, if well-maintained, can also last many years but are more prone to rust. Investing in quality materials and regular upkeep ensures your cargo box remains secure and functional over time.
