More Details on Our Top Picks

  1. GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening Luggage Storage

    GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening Luggage Storage

    Best Overall for Versatility and Weather Resistance

    View on Amazon

    The GarveeTech rooftop cargo box stands out for its durable ABS construction and dual-sided opening, making it highly accessible during long trips. Compared to the Rough Country option, it offers better weather resistance with UV protection, but it is slightly less spacious at 12 cubic feet versus 14.5. Its compatibility depends on your roof rack fit, which could limit its use for some vehicles. This model is a solid choice for travelers who prioritize weatherproofing and security, though it requires roof rack compatibility. If you need a reliable, weather-resistant carrier with easy access, this is a worthy contender.

    Pros:
    • Durable and weather-resistant construction
    • Generous 12 cubic feet of storage space
    • Dual-sided opening for easy access
    • Includes security keys and straps
    Cons:
    • Compatibility depends on roof rack fitting
    • Limited to vehicles with roof racks

    Best for: Families needing durable, weatherproof storage that’s easy to access on long trips

    Not ideal for: Drivers with non-standard roof racks or vehicles without crossbars, due to compatibility constraints

    • Material:ABS
    • Capacity:12 cubic feet (340L)

  2. TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys, Waterproof Hard Shell Travel Roof Storage Carrier

    TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys, Waterproof Hard Shell Travel Roof Storage Carrier

    Best Value for Capacity and Security

    View on Amazon

    The TUFFIOM 13.4 cu.ft. cargo box offers a higher capacity than the GarveeTech, making it ideal for larger gear or extended trips. It features a locking system with keys, comparable to the Rough Country box, but at a more budget-friendly price point. Its durable ABS shell ensures weather resistance, yet it is slightly smaller in capacity. The installation requires crossbars, which may limit some vehicle compatibility. This model is best suited for those who want a balance of capacity, security, and affordability, though it demands proper crossbar dimensions for installation.

    Pros:
    • Large 13.4 cubic feet capacity
    • Secure locking system with keys
    • Waterproof ABS material
    • Relatively affordable
    Cons:
    • Requires crossbars for installation
    • Peeling protective film may need removal before use

    Best for: Budget-conscious travelers needing secure, large-capacity storage for long trips

    Not ideal for: Drivers without crossbars or with non-standard roof rack setups, due to installation requirements

    • Capacity:13.4 cubic feet
    • Dimensions:61″ L x 27.6″ W x 13.8″ H
    • Material:ABS
    • Max Load Capacity:150 lbs
    • Warranty:3 years
    • Compatibility:Most vehicles with crossbars, max bar width 2.36″
    Our verdict
    “This option is ideal for those seeking a roomy, secure cargo solution without overspending, provided their vehicle supports crossbar installation.”
  3. Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box

    Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box

    Best for Easy Installation and Simple Capacity Boost

    View on Amazon

    This universal ABS plastic cargo box provides a straightforward way to increase storage without complex setups. Its 110 lbs weight limit makes it less suitable for heavy gear compared to larger or more robust options, but its simple crossbar mounting makes installation quick and tool-free for many vehicles. The secure lock adds peace of mind, though the limited color choices and installation challenges without instructions may be drawbacks. It’s a practical choice for travelers who prioritize quick setup over maximum capacity or rugged features.

    Pros:
    • Easy to install on cross bars without tools
    • Secure locking mechanism
    • Weather-resistant construction
    • Increases vehicle cargo capacity
    Cons:
    • Fits only vehicles with cross bars
    • May be challenging to install without clear instructions

    Best for: Casual road trippers seeking quick, easy cargo expansion without heavy-duty needs

    Not ideal for: Long-term heavy-duty hauling or large groups, due to its limited weight capacity

    • Material:ABS plastic
    • Capacity:110 lbs
    • Dimensions:53 x 34 x 15 inches
    • Color:Black textured finish
    • Lock:Secure key lock
    • Includes:Cargo box, keys, mounting brackets and hardware
    Our verdict
    “A practical, quick-install option for those who need an extra cargo boost without fuss, suitable for smaller loads or short trips.”
  4. YZONA Roof Rack Cargo Basket 55”x41” with 2 LED Light Bars & Cargo Net

    YZONA Roof Rack Cargo Basket 55''x41'' with 2 LED Light Bars & Cargo Net

    Best for Heavy-Duty and Visibility Enhancement

    View on Amazon

    The YZONA cargo basket is designed for heavy-duty use, supporting up to 150 lbs and adding significant cargo space with its 55” x 41” footprint. Its steel construction offers durability, and the included LED light bars improve visibility during night loading or off-road conditions. Compared to enclosed boxes like the Rough Country, this basket provides open-air capacity, ideal for bulky gear or outdoor equipment, but it doesn’t protect against weather. Its installation requires specific crossbar dimensions and some mechanical skill, making it less suited for casual users. This choice makes the most sense for adventurers who need a rugged, open platform with enhanced visibility.

    Pros:
    • Heavy-duty steel construction
    • Supports up to 150 lbs
    • Includes LED light bars for enhanced visibility
    • Large, open cargo space
    Cons:
    • Requires specific crossbar dimensions for installation
    • Installation can be complex
    • Open design offers no weather protection

    Best for: Outdoor enthusiasts needing a durable, visible cargo platform for off-road or heavy-duty trips

    Not ideal for: Urban drivers or those seeking weatherproof enclosure, due to open design

    • Dimensions:55” x 41” x 7”
    • Max Load Capacity:150 lbs
    • Material:Hot-rolled steel
    • Weather Resistance:Yes
    • Included Components:2 LED light bars, cargo net, hardware
    Our verdict
    “Ideal for rugged use and outdoor adventures where visibility and heavy load capacity outweigh weather protection.”
  5. Rough Country Rooftop Cargo Box 14.5 Cu Ft – Hard Shell Roof Rack Storage Carrier

    Rough Country Rooftop Cargo Box 14.5 Cu Ft – Hard Shell Roof Rack Storage Carrier

    Best for Maximum Capacity and Weatherproof Security

    View on Amazon

    The Rough Country 14.5 cu ft cargo box offers the largest capacity among these options, making it ideal for large families or extensive gear. Its UV-protected ABS shell ensures weatherproofing, and its lockable design provides security during long stops. Compared with the GarveeTech, it may be heavier when loaded, but it compensates with a larger volume. Installation is straightforward on most crossbars, and the no-drill setup reduces vehicle modification concerns. However, its bulk and weight can make handling cumbersome, and it may be overkill for those with minimal cargo needs. This choice is best for those prioritizing space and weather protection over ease of handling or minimal vehicle impact.

    Pros:
    • Largest capacity among reviewed options
    • Weatherproof and UV-protected
    • Lockable for security
    • Easy to install without drilling
    Cons:
    • Heavy when fully loaded, harder to handle
    • May be over-sized for small vehicles

    Best for: Large families or outdoor groups needing maximum cargo space and weatherproof security

    Not ideal for: Drivers with small roofs or limited crossbar support, due to size and weight

    • Capacity:14.5 cu ft
    • Interior Dimensions:65″ L x 32″ W x 13″ H
    • Max Load:125 lbs
    • Material:UV-protected ABS
    • Installation:No drill, universal crossbar fit
    • Warranty:3 years
    Our verdict
    “This cargo box is best for those needing ample, weatherproof storage for long trips with bulky gear, accepting some handling challenges.”
  6. SportRack Vista XL Rear Opening Cargo Box

    SportRack Vista XL Rear Opening Cargo Box

    Best for Large Capacity and Rear Access

    View on Amazon

    The SportRack Vista XL stands out for its generous 18 cubic feet capacity, making it ideal for long trips with multiple travelers or bulky gear. Its rear-opening design simplifies loading and unloading, especially when parking space is tight. Compared with the Thule Pulse 2 L, it offers slightly more capacity but may be less aerodynamic and more challenging to install on some rack systems. The tool-free mounting system streamlines setup, though its maximum load of 100 pounds could limit heavier gear. Its UV-resistant ABS material ensures durability over many trips, but compatibility issues may arise with certain rack configurations. Best for families or groups needing maximum storage space with easy rear access. Not ideal for smaller vehicles or those with limited roof space, due to its size and weight capacity. Pros include a large capacity, easy rear access, and secure lock. Cons involve potential fit issues and weight restrictions. This cargo box works well for those prioritizing capacity over compactness.

    Pros:
    • Large 18 cubic foot capacity for ample storage
    • Easy rear access for convenience
    • Tool-free mounting hardware simplifies installation
    • Secure lock to protect contents
    Cons:
    • May not fit all rack types; check compatibility
    • Maximum weight limit of 100 pounds could restrict heavy loads

    Best for: Families or groups needing maximum storage space for long trips with easy rear access

    Not ideal for: Small cars or vehicles with limited roof space, due to its size and weight

    • Capacity:18 cubic feet
    • Material:UV-resistant ABS
    • Dimensions:63 x 38 x 19 inches
    • Max Weight Capacity:100 pounds
    • Min-Max Crossbars Spacing:23 5/8 – 29 3/4 inches
    Our verdict
    “Ideal for those needing maximum capacity and rear access on long trips, but check roof compatibility first.”
  7. Thule Pulse 2 L Roof Mounted Box, 16 Cubic Ft, Dual-Side Opening

    Thule Pulse 2 L Roof Mounted Box, 16 Cubic Ft, Dual-Side Opening

    Best for Versatile Gear Transport and Easy Access

    View on Amazon

    The Thule Pulse 2 L makes a strong case for versatile long-trip storage, offering 16 cubic feet of weather-resistant space. Its dual-side opening allows easy access from either side, which is especially helpful when parking in tight spots or crowded lots. Compared to the Rooftop Cargo Box (15.5 cu ft), it provides similar capacity but with a more streamlined, aerodynamic profile that reduces wind noise and drag. Installation is straightforward with a secure, tool-free system, though the box’s bulk may pose challenges for smaller vehicles or lower-clearance racks. The ASA-ABS plastic resists harsh weather, ensuring gear stays dry. This pick is best for those seeking flexible access and reliable weatherproofing. Not ideal for compact cars or vehicles without compatible roof racks, as it may be bulky. Pros include weather resistance, dual-side access, and easy setup. Cons involve size and the need for a roof rack for mounting. It’s well-suited to active travelers who carry sports gear or luggage and want quick, side access.

    Pros:
    • Large cargo capacity suitable for various gear
    • Easy, tool-free installation with secure attachment
    • Weather-resistant ASA-ABS construction
    • Dual-side opening for convenient access
    Cons:
    • May be bulky for smaller vehicles
    • Requires roof rack for installation

    Best for: Active travelers needing flexible access for sports gear and luggage with weather resistance

    Not ideal for: Small vehicles or those without a compatible roof rack, due to its size and bulk

    • Capacity:16 cubic feet
    • Load Capacity:75 kg
    • Material:ASA-ABS plastic
    • Access:Dual-side opening
    Our verdict
    “Excellent for active users needing weatherproof, dual-access storage on larger vehicles.”
  8. Rooftop Cargo Box, 15.5 Cubic Ft, Black

    Rooftop Cargo Box, 15.5 Cubic Ft, Black

    Best for Budget-Conscious Family Travel

    View on Amazon

    The Black Rooftop Cargo Box offers 15.5 cubic feet of weather-resistant storage, making it a practical choice for families on a budget. Its dual-side access, combined with a three-point locking system, enhances convenience and security. Compared with the SportRack Vista XL, it’s slightly smaller in capacity but easier to fit on a variety of vehicles without risking overloading. The tool-free mounting system simplifies installation, though its weight can make handling cumbersome when fully loaded. Its durable ABS plastic and PMMA components withstand weather over many trips, but the limited color options and potential heaviness when loaded are tradeoffs. This option suits budget-conscious families who prioritize ease of use and security. Not ideal for those needing maximum capacity or lightweight solutions. Pros include weather resistance, dual access, and affordability. Cons involve weight and limited color choices. It’s a solid pick for family trips where cost and reliability matter most.

    Pros:
    • Weather-resistant and durable construction
    • Dual-sided access for convenience
    • Three-point lock for security
    • Easy, tool-free installation
    Cons:
    • Limited color options (only black)
    • Potentially heavy when fully loaded

    Best for: Budget-conscious families seeking reliable, secure storage for long trips

    Not ideal for: Travelers needing maximum capacity or lightweight carriers, due to weight and size

    • Capacity:15.5 cubic feet
    • Weight Capacity:130 lbs
    • Material:ABS plastic and PMMA
    • Locking Mechanism:Three-point lock
    Our verdict

  9. Rooftop Cargo Carrier, 18 Cu Ft Hardshell, Heavy-Duty, Made in USA

    Rooftop Cargo Carrier, 18 Cu Ft Hardshell, Heavy-Duty, Made in USA

    Best for Heavy-Duty, Weatherproof Security

    View on Amazon

    The Heavy-Duty Rooftop Cargo Carrier is tailored for long-distance trips requiring durable, weatherproof protection. Its 18 cubic feet capacity and HDPE shell ensure the highest level of toughness and weather resistance among the options. Compared with the Thule Pulse 2 L, it offers a similar capacity but prioritizes rugged durability and security, with dual side locking and a weather-tight seal. Its large size may limit compatibility with vehicles that have smaller roof space, and its weight can complicate installation. Being made in the USA, it also appeals to those valuing domestic manufacturing. The heavy-duty construction makes it ideal for rough conditions or heavy gear, though it might be overkill for casual travelers. This is best for those needing maximum durability and weatherproofing in a rugged design. Not ideal for small or low-clearance vehicles due to its bulk and size. Pros include weatherproofing, heavy-duty durability, and dual locking. Cons involve size and installation complexity. Perfect for adventurers or those hauling heavy, valuable gear on long, challenging trips.

    Pros:
    • Weatherproof and secure storage
    • Heavy-duty HDPE shell for rugged durability
    • Dual side locking for added security
    • Made in USA
    Cons:
    • Large size may limit vehicle compatibility
    • Potentially difficult to install for some users

    Best for: Adventurers or travelers needing durable, weatherproof storage for heavy or valuable gear

    Not ideal for: Small or low-clearance vehicles, due to its size and bulk

    • Capacity:18 cubic feet
    • Material:HDPE plastic
    • Dimensions:57 L x 38.5 W x 17.75 H inches
    • Made in:USA
    Our verdict

    21 Cu Ft Cargo Box, Hard Shell Roof Cargo Carrier with Security Keys, Dual-Side Opening, ABS Material, Weight Capacity up to 150 lbs, Tool-Free Install, White

    Best for Maximum Capacity and Security

    View on Amazon

    The 21 Cu Ft Cargo Box offers the largest capacity in this roundup, with 21 cubic feet of impact-resistant ABS storage. Its dual-side opening allows easy access from either side, making it ideal for long trips where quick retrieval of gear is essential. Compared with the SportRack Vista XL and Rooftop Cargo Carrier, this model provides more space and a higher weight capacity of 150 pounds, suitable for bulky, heavy, or numerous items. Its tool-free installation simplifies setup, though it depends heavily on roof bar compatibility. The impact-resistant ABS provides durability, but the key lock system introduces a potential security vulnerability if keys are lost. This carrier is best suited for those who need maximum space and secure, easy access. Not ideal for smaller vehicles or those looking for lightweight options. Pros include the highest capacity, impact resistance, and dual access. Cons involve roof compatibility and security concerns with keys. This is a smart choice for large families or those carrying heavy gear on extended trips.

    Pros:
    • Largest capacity at 21 cubic feet
    • Impact-resistant ABS construction
    • Dual-side opening for easy access
    • High weight capacity of 150 lbs
    Cons:
    • Dependent on compatible roof bars
    • Security relies on keys, risking loss

    Best for: Large families or groups needing maximum capacity and secure access for long trips

    Not ideal for: Owners of small or low-clearance vehicles, due to its size and mounting requirements

    • Dimensions:70.08 × 34.57 × 14.53 inches
    • Capacity:21 cubic feet
    • Weight Capacity:150 lbs
    • Material:ABS and PMMA
    • Opening:Dual-side
    Our verdict
    “Best suited for those needing maximum storage and secure, quick access on long journeys.”
  11. OMAC 9.5 cu ft Car Roof Cargo Box Carbon Finish Snap-Open Lid – Lockable, Aerodynamic, 121 lbs Capacity

    OMAC 9.5 cu ft Car Roof Cargo Box Carbon Finish Snap-Open Lid - Lockable, Aerodynamic, 121 lbs Capacity

    Best for Small Vehicles Needing Secure, Space-Saving Storage

    View on Amazon

    The OMAC 9.5 cu ft cargo box excels in providing a compact, aerodynamic solution ideal for small and compact vehicles. Compared with larger options like the 72 Inch Rooftop Cargo Box, this model is more space-efficient and easier to handle on smaller roofs, but it sacrifices some capacity—making it less suitable for those with hefty gear or multiple travelers. Its lockable lid enhances security, and the TÜV certification affirms safety, yet it requires assembly and isn’t as versatile for larger loads. This pick makes sense for drivers prioritizing secure, space-efficient storage without the bulk of bigger boxes.

    Pros:
    • Compact and aerodynamic design minimizes wind resistance
    • Supports up to 121 lbs for safe cargo transport
    • Lockable lid adds security for valuables
    Cons:
    • Assembly required can be time-consuming
    • Limited capacity may necessitate multiple boxes for large loads

    Best for: Owners of small or compact vehicles needing secure, space-saving cargo for long trips

    Not ideal for: Families with bulky gear or multiple passengers requiring high volume storage

    • Capacity:9.5 cu ft
    • Weight Capacity:121 lbs
    • Finish:Carbon
    • Locking System:Lockable aluminum front
    • Certification:TÜV GS
    Our verdict
    “This cargo box suits owners of small cars seeking secure, space-efficient storage for long trips, but it’s less ideal for large families or bulky gear.”
  12. 72 Inch Rooftop Cargo Box Carrier, 21 Cu Ft, Heavy Duty, Black

    72 Inch Rooftop Cargo Box Carrier, 21 Cu Ft, Heavy Duty, Black

    Best for Large Loads and Outdoor Adventures

    View on Amazon

    The 72 Inch Rooftop Cargo Box offers a substantial 21 cubic feet of storage, making it well-suited for long family trips or outdoor enthusiasts with bulky gear. Unlike the smaller OMAC box, this model provides ample capacity, but it comes with increased weight—potentially challenging for handling when fully loaded. Its durable ABS and PMMA construction ensures weather resistance, and the side-opening design simplifies access, especially when parked on tight streets. Installation is straightforward, requiring no tools, yet it demands compatible roof crossbars and can be heavy when filled. This box makes the most sense for travelers prioritizing volume and durability over ease of handling.

    Pros:
    • Huge 21 cubic feet capacity accommodates large loads
    • Weather-resistant, durable materials protect cargo
    • Easy no-tool installation speeds setup
    Cons:
    • Heavy when fully loaded, potentially difficult to handle
    • Requires compatible roof crossbars for installation

    Best for: Families or outdoor adventurers needing maximum cargo space for long trips

    Not ideal for: Drivers with small or mid-sized vehicles who don’t require large capacity, or those seeking lightweight options

    • Dimensions:72.83 x 34.25 x 14.76 inches
    • Capacity:21 cubic feet
    • Weight Limit:150 lbs
    • Material:ABS and PMMA
    • Opening:Side
    • Locking System:Key and lock
    Our verdict
    “This cargo box is best for users needing maximum volume and weather resistance, but it may be cumbersome for everyday handling or smaller vehicles.”

Factors to Consider When Choosing Roof Cargo Box For Long Trips

Choosing the right roof cargo box for long trips involves more than just capacity. Several factors influence how well a model will serve your specific needs, from ease of access to durability in harsh weather. Understanding these factors can help you avoid common mistakes like overpaying for unnecessary features or selecting a size that doesn’t fit your vehicle. Below are the key considerations to keep in mind when narrowing down your options.

Capacity and Size

Long trips often require transporting a significant amount of gear, so capacity becomes a primary factor. Larger models can hold more, but they might also be heavier and more challenging to install or remove. Measure your roof space carefully and compare it with the product dimensions to ensure compatibility. Remember, a slightly smaller box might be easier to handle and still meet your needs, especially if your gear is organized efficiently.

Ease of Access

Accessibility impacts convenience, especially when loading or unloading at rest stops. Dual-side opening models provide easier access from either side of the vehicle, which is a major advantage in tight parking situations. Rear-opening boxes can be simpler to load when parked in driveways but may be less convenient when on the road. Consider your typical parking environment and how often you’ll need quick access to your gear.

Durability and Weather Resistance

Since long trips expose your gear to various weather conditions, a weatherproof and rugged construction is vital. Look for models with high-quality ABS or fiberglass shells, sealed edges, and secure locks. A poorly sealed cargo box can lead to water ingress, damaging your belongings. Investing in a durable, weather-resistant model helps ensure your gear stays dry and protected throughout the journey.

Installation and Compatibility

Not all cargo boxes fit every roof rack, so compatibility is a key consideration. Check your vehicle’s roof type and existing rack system before purchasing. Ease of installation also varies; some models feature tool-free mounting, which saves time and effort. A secure, straightforward installation process reduces the risk of damage or accidents during long trips.

Security Features

Extended trips mean leaving your gear unattended at times, making security features like lockable lids important. High-quality locks prevent theft and tampering, giving peace of mind. However, more advanced locking mechanisms may add to the cost and complexity. Weigh the importance of security against budget and convenience factors based on your travel plans.

Frequently Asked Questions

Will a larger cargo box affect my vehicle’s fuel efficiency?

Yes, larger and heavier cargo boxes can increase wind resistance and overall weight, which may reduce fuel efficiency over long distances. The impact varies based on the box’s size, shape, and your vehicle’s design. Aerodynamic models tend to minimize drag, helping to offset some of the fuel costs. If fuel economy is a priority, balancing capacity with aerodynamic design is advisable.

Can I install a roof cargo box myself, or should I hire a professional?

Most roof cargo boxes are designed for DIY installation, especially those with tool-free mounting systems. Following the manufacturer’s instructions carefully usually suffices, and many users find it straightforward to attach and remove the box as needed. However, if your roof rack system is unusual or you feel unsure about secure attachment, consulting a professional can prevent potential damage or safety issues during long trips.

How does weatherproofing impact long-term durability?

Weatherproofing directly correlates with a cargo box’s ability to protect your gear from rain, snow, and road spray. Well-sealed, durable materials like ABS or fiberglass resist cracking, UV damage, and water ingress, extending the lifespan of the product. Investing in a weatherproof model ensures your gear remains dry and undamaged, making it a wise choice for frequent or long-distance travel in diverse climates.

Is it worth paying more for a premium roof cargo box?

Higher-priced models often offer better durability, aerodynamics, security, and ease of access, which can be valuable during extended trips. They tend to withstand harsh weather conditions and last longer, providing better value over time. However, if your trips are infrequent or short, a budget model might suffice without sacrificing functionality, especially if it meets your size and security needs.

How can I maximize storage space while maintaining vehicle stability?

Distributing weight evenly across your roof rack and staying within the cargo box’s weight limit helps maintain vehicle stability. Avoid overloading the box or placing heavy items at one end. Also, consider the overall height of your vehicle with the cargo box attached, making sure you can clear parking garages and low-clearance areas. Properly securing your gear prevents shifting that could affect handling or damage your vehicle.

Conclusion

For the most comprehensive long-trip solution, the Thule Pulse 2 offers superior durability, security, and ease of access, making it ideal for frequent travelers or those with high capacity needs. The Rooftop Cargo Carrier 18 Cu Ft provides excellent value for budget-conscious users who still need ample space. If you prefer a premium, aerodynamic design, the SportRack Vista XL or similar models will serve well. Beginners or occasional users might find simpler, tool-free models more suitable, while those with specific security needs should prioritize lockable options. By aligning your choice with your trip frequency, vehicle compatibility, and storage demands, you’ll find the perfect roof cargo box for your long journeys.
