Yakima SkyBox NX XXL Rooftop Cargo Carrier Hard Shell Box with SKS Lock
The Yakima SkyBox NX XXL stands out for its generous 22 cu ft capacity, making it an excellent choice for large families or extended trips. Its dual-sided access simplifies loading and unloading from either side, a feature that offers real convenience compared to smaller or single-access boxes like the Thule Pulse 2 L. The SKS lock system adds a layer of security, especially valuable when leaving gear unattended. However, this model can be quite heavy, which may pose challenges during installation, especially for solo users. Limited color options and the absence of specific price details could also influence purchasing decisions. Overall, this box makes the most sense for those prioritizing maximum space and security, willing to handle heavier gear during setup.
Pros:- Large 22 cu ft storage capacity for ample gear
- Dual-sided access simplifies loading from either side

Its tool-free, secure attachment system makes for straightforward installation, especially compared to bulkier options like the Yakima CBX XXL. Dual-side opening improves accessibility, a helpful feature for frequent loading. Nonetheless, its size can be a limitation for small vehicles, and at high speeds, some users report increased noise levels. Compared with larger models, the Thule Pulse 2 L is less bulky but also offers less capacity, making it a better fit for mid-sized families or light gear needs while maintaining durability.
Pros:- Weather-resistant ASA-ABS plastic construction

Its quick, secure mounting system and safety indicators make it suitable for busy families or outdoor enthusiasts who need reliable, everyday access. While it shares some features with the Yakima SkyBox NX XXL, it’s generally more geared toward regular, active use rather than maximum capacity. Customer reviews are mixed, suggesting some variability in quality or installation experience. The lack of detailed specifications can be a drawback for buyers who want comprehensive info upfront. This model appeals most to those seeking a durable, versatile box for regular trips, though it might fall short for those needing the largest possible capacity.
Pros:- Durable, sleek design suitable for daily use
- Easy, quick mounting with safety indicators

GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening, 12/14 Cubic Feet

Its universal fit and dual-sided opening enhance accessibility, similar to more premium options like the Yakima CBX XXL, but with a smaller capacity. While it’s compatible with most roof racks, the lack of detailed mounting hardware info and average customer ratings suggest it might require some careful installation or compromise. It’s perfect for those on a budget who still want durable, waterproof protection, but it’s not ideal for large gear loads or frequent heavy-duty use.
Pros:- Durable, waterproof, UV-resistant construction
- Universal fit for most roof racks
- Dual-sided opening for convenience
Cons:- Limited capacity compared to larger models
- Some users find the quality or mounting hardware lacking

Our verdict“A solid choice for budget-minded buyers needing waterproof, UV-resistant protection for moderate loads, accepting some size limitations.”
Yakima CBX XXL Vehicle Rooftop Cargo Gear Box, 21.5 Cu Ft, Black
The Yakima CBX XXL offers a substantial 21.5 cu ft capacity, making it a top contender for carrying snowboards, skis, and bulky gear. Its dual-sided opening makes access straightforward, and the secure SKS locks provide peace of mind. Its rugged, angular finish gives it a stealth-like appearance, suitable for those who want a stylish yet functional carrier. Compared with the Thule Force XT XXL, it provides slightly more capacity but is also heavier and larger, which could complicate installation or vehicle compatibility. The high price point might deter budget buyers, but for those with ample cargo needs, this model delivers significant space with reliable security.

Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box
This cargo box stands out for its durable ABS plastic construction, making it highly resistant to weather and impact. Compared with larger models like the Thule Motion 3, it offers a more universal fit for vehicles with cross bars, but with a tradeoff—its limited color options and potential need for extra mounting hardware can complicate setup. Its secure lock adds peace of mind during travel, and the easy installation process appeals to DIY enthusiasts. However, it only fits vehicles equipped with cross bars, which limits compatibility. For those seeking a tough, weatherproof option that’s straightforward to install, this model is a strong choice.
Pros:- Durable and weather-resistant ABS plastic construction
- Easy to install without tools
- Secure lock provides peace of mind
Cons:- Fits only vehicles with cross bars

Hard Shell Extra Large Rooftop Cargo Carrier, 21 Cu Ft, White
This model makes the most of its 21 cubic feet capacity, offering ample space for luggage, camping gear, or sports equipment, surpassing smaller options like the 14 cu ft box. Its dual-side opening enhances accessibility, especially when parked in tight spots, and the secure locking system adds security. Compared to the impact-resistant DNA Motoring XXL, this box’s larger volume and straightforward, tool-free installation appeal to those with extensive gear needs. However, its weight can be a challenge during mounting, and wind noise remains a concern despite aerodynamic design. This box suits travelers prioritizing maximum storage with convenient access from either side.
Pros:- Large 21 cu ft capacity for substantial storage
- Dual-side opening for easy access
- Secure locking system with keys
Cons:- Heavy weight may require assistance for mounting

DNA Motoring XXL Rooftop Cargo Carrier Lockable Heavy Duty Roof Storage Box, 17 Cubic Feet, 110Lb Capacity, Glossy Black
This box offers a solid 17 cubic feet of storage with a focus on security and impact resistance, making it a good alternative to the larger Thule Motion 3 for those who prioritize durability. Its lockable lid and impact-resistant ABS ensure belongings stay safe even in rough weather, though it’s more suited to vehicles with cross bars, similar to the other options like the Hard Shell Waterproof Box. Its weight of 37 lbs can be a hurdle for solo installers, and its specific vehicle compatibility limits flexibility. If you need a tough, lockable cargo solution that’s easy to secure, this model fits the bill.
Pros:- Large 17 cu ft storage capacity
- Secure locking system with keys
- Impact-resistant, durable construction
Cons:- Designed only for vehicles with cross bars

This 14 cu ft cargo box offers a balanced mix of space and security, with dual side opening that simplifies access compared to single-opening models. Its durable construction and included lock keys provide peace of mind, aligning with models like the DNA Motoring box but at a lower price point. Installation is straightforward but not fully DIY—professional help might be needed, adding some cost.

Thule Motion 3 Rooftop Box
The Thule Motion 3 combines sleek, aerodynamic styling with a spacious interior, making it ideal for modern adventurers who value both form and function. Its quick-mount PowerClick system and integrated torque indicator simplify installation, comparable to the ease of the Thule Force XT XXL but with a more refined appearance. The SlideLock system ensures secure closure, and the spacious interior accommodates various outdoor gear, surpassing smaller models like the Thule Pulse 2. However, the lack of detailed pricing information and some user reports about installation challenges mean it’s best suited for those willing to invest time in setup. For users prioritizing appearance, ease of use, and capacity, this model delivers.
Pros:- Aerodynamic design reduces drag and improves fuel efficiency
- Easy to mount with PowerClick quick-mount system
- Secure SlideLock system with separate locking and opening functions

SportRack Vista XL Rear Opening Cargo Box
The SportRack Vista XL stands out for its large 18 cubic foot capacity combined with a rear-opening design, making access straightforward without removing the entire box. Compared with the Yakima CBX LG, which offers similar capacity and dual-sided access, Vista XL is easier to operate for those who prioritize rear access over side loading. Its durable UV-resistant ABS construction ensures longevity, especially in harsh sunlight, but the fit is limited to specific rack systems, and the 100-pound weight limit could restrict heavier gear. This pick makes the most sense for users needing maximum capacity with simple rear access and quick, tool-free installation.
Pros:- Large 18 cubic foot storage capacity for bulky gear
- Durable UV-resistant ABS material withstands weather
- Rear opening simplifies access without removing the box
Cons:- Fits only certain rack systems, so compatibility check is necessary
- Maximum weight capacity of 100 pounds may limit heavier loads
Best for: Families or travelers who need large, easy-to-access storage during road trips and prefer rear opening for convenience
Not ideal for: Solo users or those with racks that don’t match the specific dimensions, since compatibility may be limited

- Material:UV-resistant ABS
- Dimensions:63 x 38 x 19 in / 160 x 96.5 x 48 cm
- Max Weight Capacity:100 pounds (45 kg)

Our verdict“This cargo box is ideal for those seeking maximum capacity with rear access, provided their rack system matches.”
Yakima CBX LG 16 Cu Ft Premium Rooftop Cargo Box with SKS Locks, Black
The Yakima CBX LG offers a generous 16 cubic feet of space, making it suitable for multiple travelers’ gear, including skis up to 185 centimeters. Its dual-sided opening allows for quick access from either side, a feature that beats the rear-only access of the Vista XL when multiple people need to load or unload. The SKS locks provide enhanced security, ideal for valuable gear, but the box’s weight and size can be challenging to install solo, especially compared with lighter models like the TUFFIOM. It’s best suited for those who prioritize security and easy access over simplicity of installation or lower price points.
Pros:- Large capacity suitable for multiple travelers
- Dual-sided opening for flexible access
- Secure SKS locks for valuables
Cons:- Heavy and large, making installation difficult alone
- High price due to premium features
- Limited color options
Best for: Travelers who need secure, large-capacity storage with easy multi-access from both sides

- Capacity:16 cubic feet
- Dimensions:91 x 38 x 17 inches
- Max Snowboard/Ski Length:185 centimeters
- Material:Rugged, angular finish with stealth-like texture
- Locks:SKS locks

Our verdict“This cargo box is perfect for security-conscious travelers who value dual access and ample space, despite its higher cost and weight.”
Roof Cargo Box, 26 Cubic Feet Capacity, Dual-Side Opening
The 26 Cubic Feet Capacity Roof Cargo Box excels for its enormous storage volume combined with an aerodynamic shape that helps reduce wind noise and improve fuel efficiency. Its dual-side opening simplifies loading from either side, a step up from rear-only access models like the Vista XL. Compared to the Yakima CBX LG, this box offers more volume but with a heavier, bulkier profile, which might challenge installation on smaller vehicles. Its durable UV-resistant construction withstands bad weather, making it a reliable choice for long trips with lots of gear, including skis and snowboards. It’s best for families or groups with extensive gear needs and a vehicle capable of handling its size.
Pros:- Enormous 26 cubic feet capacity for all gear
- Dual-side opening for quick access from either side
- Aerodynamic shape enhances fuel efficiency
Cons:- Heavy weight may require assistance for installation
- Long dimensions could limit compatibility with some vehicles

Our verdict“This is a top choice for large families or groups who need maximum capacity and easy dual access, despite its weight and size challenges.”
TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys, Waterproof Hard Shell Travel Roof Storage Carrier
The TUFFIOM 13.4 cu.ft. cargo box offers a balanced mix of size and capacity, making it suitable for those who want a smaller footprint without sacrificing too much space. Its dual-side opening and secure key lock enhance usability and safety, especially compared to larger, heavier options like the Roof Cargo Box with 26 cu ft. While its 13.4 cubic feet capacity is less than others, it’s still ample for long skis or a few bags, and its streamlined design reduces drag, unlike bulkier carriers. However, the necessity for crossbars with specific dimensions and the protective film on the lid may add minor inconveniences. It’s best suited for users who prioritize ease of handling and weather protection in a more manageable size.
Pros:- Easy dual-side access simplifies loading
- Secure locking system with keys for safety
- Weather-resistant ABS material protects belongings
Cons:- May require crossbars with specific dimensions for compatibility
- Protective film on lid needs removal before use
Best for: Solo travelers or small families seeking a reliable, weatherproof cargo box that’s easier to install and handle
Not ideal for: Large groups or those with extensive gear, due to its smaller capacity and specific crossbar requirements
- Capacity:13.4 cubic feet
- Max Load Capacity:150 lbs
- Dimensions:61″ L x 27.6″ W x 13.8″ H
- Material:ABS
- Weight:approximately 24.25 lbs

Factors to Consider When Choosing Rated Extra Long Rooftop Cargo Boxes
Choosing the right rated extra long rooftop cargo box involves understanding several key factors that influence usability, durability, and value. Beyond just capacity, it’s important to consider features like access, security, and compatibility with your vehicle. Making informed decisions helps avoid common pitfalls, like overpaying for unnecessary features or selecting a size that doesn’t fit your car or storage needs. Here are the main factors to keep in mind:Capacity and Size
The primary reason for choosing an extra long cargo box is increased storage space. However, bigger isn’t always better if it exceeds your vehicle’s roof capacity or makes handling difficult. Measure your vehicle’s roof and consider how much cargo you’ll realistically carry. A box that is too large may also affect fuel efficiency and stability, so balance capacity with practical considerations.
Access and Opening Mechanisms
Ease of access is crucial, especially for loading and unloading. Dual-side opening models offer more convenience, allowing you to reach cargo from either side of the vehicle. Think about your parking environment—if you often park in tight spots, this feature can save time and hassle. Also, consider the quality of hinges and latches for long-term durability.
Security Features
Security matters when leaving cargo on your vehicle unattended. Models with integrated locks, especially those with SKS (Same Key System), provide peace of mind. Cheaper or older models may lack robust locking, increasing theft risk. Evaluate whether the lock system is easy to use yet secure enough for your needs, especially if you’re carrying valuable or sensitive items.
Build Quality and Weatherproofing
Durability depends on high-quality materials and weatherproof seals. Hard-shell boxes made from durable plastics with reinforced edges tend to last longer and resist cracking or warping. Look for water-resistant seals and tested UV protection to keep your cargo safe from rain, snow, and sun damage. Cheaper options may crack over time or leak, so investing in quality pays off in the long run.
Compatibility and Installation
Check that the cargo box fits your vehicle’s roof rack system, including crossbars and mounting points. Some models are easier to install, saving time and effort, while others may require additional accessories. Consider the weight of the box itself as well, since heavier models can be more challenging to mount and remove. Compatibility ensures hassle-free use and maximizes the lifespan of both your vehicle and the cargo box.
Price and Value
Prices for extra long rooftop cargo boxes vary widely, reflecting features, capacity, and brand reputation. While premium models offer advanced security and ease of access, they come at a higher cost. Budget options may be sufficient for occasional use but could lack durability or security. Balance your needs with your budget, and consider investing a bit more if you plan frequent or long-distance trips.
Frequently Asked Questions
Will a larger cargo box affect my vehicle’s fuel efficiency?
Yes, adding a larger cargo box increases aerodynamic drag, which can reduce fuel efficiency, especially at highway speeds. The heavier weight also impacts acceleration and braking. To minimize these effects, opt for a well-designed, lightweight box and remove it when not in use for extended periods. Properly mounted, a larger box shouldn’t significantly impair safety or handling, but it’s a tradeoff worth considering for the extra space.
Are all extra long rooftop cargo boxes compatible with any vehicle?
Not all cargo boxes fit every vehicle, as compatibility depends on your roof rack system’s size and type. Before purchasing, check your vehicle’s roof weight limit and crossbar dimensions. Some models specify maximum roof width or weight capacity, ensuring safe installation. If your vehicle has a non-standard or low-profile roof, you may need additional adapters or a different style of mounting system.
How secure are these cargo boxes against theft?
Security varies widely; premium models often include integrated locks and SKS (Same Key System) options, providing good theft deterrence. Cheaper options might lack locking mechanisms or have simple latches that can be forced open. For valuable cargo, investing in a model with a robust lock system is wise. Securing the box to your roof rack and parking in well-lit areas also adds layers of security.
How do I maintain and clean my rooftop cargo box?
Regular cleaning with mild soap and water keeps the exterior looking good and prevents buildup of dirt or debris. Check seals periodically for cracks or gaps to maintain weatherproofing. Lubricate hinges and locks as recommended by the manufacturer to ensure smooth operation over time. Avoid abrasive cleaners that could scratch the surface, and store the box in a dry place when not in use to prolong its lifespan.
Is it worth paying more for a higher capacity or premium features?
Paying more can be justified if you frequently carry large loads or value features like enhanced security, dual-side opening, or lightweight materials. Premium models often last longer, resist weathering better, and offer added convenience, which can improve your overall experience. However, if occasional use is your goal, a more affordable option might meet your needs without the extra cost. Consider your typical usage and storage needs when deciding.
Conclusion
For most buyers, the Yakima SkyBox NX XXL offers a reliable combination of capacity, security, and ease of use, making it the best overall choice. Those seeking the best value should consider models like the Thule Pulse 2 L, which balances size and affordability. If you prioritize premium features and top-tier durability, the Yakima CBX XXL or Thule Force XT XXL are excellent options. Beginners or casual users will find simpler, lighter models easier to handle, while those with larger vehicles or frequent trips benefit from the extra capacity and high-security features of the top-tier choices.
