More Details on Our Top Picks
Rooftop Cargo Box, 13 Cubic Ft, for Family Travel and Road Trips, Black
This cargo box stands out for its large 13 cubic feet capacity combined with durable, weather-resistant materials, making it ideal for families needing ample space. Unlike the Thule Force XT, it offers dual-sided access with a straightforward locking system, but installation may be more challenging for some users, especially if their crossbar setup isn’t compatible. Its impact-resistant ABS plastic ensures durability against the elements, a key advantage over softer, less weatherproof options. While it doesn’t include high-tech features, its universal mounting brackets make it flexible for most vehicles. The main tradeoff is that it might require some effort to install securely, especially on complex crossbar systems. This pick is perfect for families who want reliable, spacious storage without fussing over high-end accessories or complex setup.
Pros:- Generous 13 cubic feet capacity for all family gear
- Weather-resistant and impact-resistant construction
- Dual-sided access for convenient loading and unloading
- Secure locking system to protect valuables
Cons:- Potential compatibility issues with certain crossbar setups
- Installation can be challenging for beginners
Best for: Families needing a large, durable cargo solution for extended road trips with easy access to all gear.
Not ideal for: Owners of small or irregularly shaped vehicles where installation space is limited or crossbar compatibility is uncertain.
- Capacity:13 cubic feet
- Material:Impact-resistant ABS plastic and PMMA
- Weight Capacity:130 lbs
- Color:Black
- Installation:Universal mounting brackets for round, square, or aerodynamic crossbars
Our verdict“This cargo box offers ample space and durability for large families prioritizing capacity over simplicity of installation.”
Thule Force XT Cargo Box
The Thule Force XT is a highly durable, well-tested option crafted for frequent travelers who need secure, easy access from both sides. Compared with the Rooftop Cargo Box, 13 Cubic Ft, for Family Travel and Road Trips, this model emphasizes safety and reliability with its extensive testing and sturdy mounting system. Its design makes loading and unloading straightforward, especially for busy families on the go. However, its bulkiness can make installation and storage more cumbersome, which might be a drawback for those with limited garage space. The limited color options and absence of high-tech features mean it’s more about function over form. This model is best suited for families who value dependable, everyday use over flashy accessories.
Pros:- Durable construction designed for daily use
- Easy, dual-sided access for quick loading
- Secure, intuitive mounting system with indicator
- Extensively tested for safety and reliability
Cons:- Can be bulky to install or store
- Limited color options may not suit all vehicles
Best for: Active families who frequently travel and need a reliable, secure cargo solution that’s easy to access from both sides.
Not ideal for: Owners with limited garage space or smaller vehicles where bulky cargo boxes would be difficult to store or install.
- Brand:Thule
- Model:Force XT
- Warranty:Limited Lifetime
- Item Type:Rooftop Cargo Box
Our verdict“The Thule Force XT is ideal for families seeking a dependable, easy-to-access cargo box for regular use and adventures.”
Rooftop Cargo Box, 13 Cubic Ft, Grey
This grey cargo box offers a robust, weatherproof design with impact-resistant materials, making it well-suited for varied outdoor conditions. It provides the same 13 cubic feet of storage as the black version but stands out for its three-point locking system that enhances security during long trips. Compared with the black model, it might be bulkier, and some users may find the installation requires minor adjustments. Its simple universal mounting brackets make setup accessible, but the size could be a concern for smaller vehicles. This box is an excellent choice for families who prioritize ruggedness and all-weather protection over sleekness or high-tech features.
Pros:- Durable, weather-resistant construction
- Impact-resistant materials for long-term durability
- Secure three-point locking system
- Universal mounting brackets for easy installation
Cons:- Bulky design may not fit smaller vehicles
- Installation could require some adjustments
Best for: Families planning outdoor adventures in variable weather, needing secure, weatherproof storage for gear.
Not ideal for: Small vehicle owners or those with tight parking spaces who might find the size cumbersome.
- Capacity:13 cubic feet
- Material:Impact-resistant ABS plastic and PMMA
- Dimensions:56″ L x 30″ W x 13.7″ H
- Weight Capacity:130 lbs
- Color:Grey
- Locking System:Three-point lock
Our verdict“This cargo box is perfect for families seeking reliable, weatherproof storage for diverse outdoor conditions.”
GarveeTech Rooftop Cargo Box Carrier, 165 LBS Capacity, Dual-Side Opening, Waterproof Hard Shell, Black
The GarveeTech Cargo Box offers 12 cubic feet of waterproof storage with a tough ABS shell, making it a solid choice for unpredictable weather. Its dual-sided opening enhances accessibility, similar to the Thule Force XT, but with a higher weight capacity of 165 lbs—great for heavier gear or multiple family members’ belongings. While its waterproofing and large capacity are significant advantages, compatibility verification with your roof rack is essential, and the limited 30-day warranty could be a concern for long-term buyers. Its aerodynamic shape helps reduce fuel consumption and noise, but the slightly smaller capacity compared to larger models like the 15.5-cubic-foot options might matter for some families. This box makes sense for those prioritizing weatherproofing and durability.
Pros:- Waterproof ABS shell protects gear in all weather
- Large 12 cubic feet capacity increases cargo space
- Dual-sided opening for easy access
- High weight capacity (165 lbs)
Cons:- Requires roof rack compatibility check
- Limited warranty period of only 30 days
Best for: Families needing a highly waterproof, high-capacity cargo solution that can handle heavier loads and rough weather conditions.
Not ideal for: Owners of lightweight vehicles or those who prefer longer warranty coverage, as the warranty period is short.
- Capacity:12 cubic feet (340 L)
- Weight Capacity:165 lbs
- Dimensions:54.3 in L x 31.5 in W x 13.4 in H
- Material:ABS plastic
- Color:Black
- Opening:Dual-sided
Our verdict“This cargo box is best suited for families seeking a durable, waterproof carrier with high load capacity for adverse weather trips.”
Thule Motion 3 Rooftop Box
The Thule Motion 3 combines sleek, aerodynamic styling with functional features, including an easy one-handed opening system and optional accessories like interior lighting. Its wing-shaped profile minimizes drag, making it more fuel-efficient than bulkier options like the Thule Force XT or the large impact-resistant boxes. However, the absence of specific capacity details makes it harder to compare directly; it likely offers less space than the larger 13-cubic-foot options but compensates with advanced design features. The quick-mount PowerClick system simplifies installation, though the price is higher due to its premium design. This model appeals to families who value cutting-edge aerodynamics and convenience over maximum capacity.
Pros:- Aerodynamic wing-shaped profile reduces drag
- Easy, secure mounting with PowerClick system
- Optional accessories for added convenience
- Reduces fuel consumption during long trips
Cons:- No explicit capacity or size details provided
- Higher cost due to advanced features
Best for: Families looking for a stylish, aerodynamic cargo box that enhances fuel efficiency and offers easy, quick installation.
Not ideal for: Those requiring maximum storage capacity or who prefer detailed size specifications for planning purposes.
- Design:Wing-shaped profile with forward-leaning nose
- Mounting System:PowerClick quick-mount with torque indicator
- Locking System:SlideLock with separate locking and opening
- Accessories:Interior box light, protective liner, storage cover
Our verdict“This cargo box is ideal for families prioritizing fuel efficiency and sleek design over maximum volume.”
Garvee Rooftop Cargo Box Carrier, Dual-Side Opening, 12 Cubic Feet, Waterproof, Universal Fit
The Garvee Rooftop Cargo Box stands out with its dual-sided opening, making access effortless from either side—an advantage over the Thule Pulse 2, which only opens from one side. Its 12 cubic feet of weather-resistant storage offers ample space for medium-sized family gear, though its customer rating below 4 stars and only one-year warranty suggest potential durability concerns. Compared to larger options like the WORKPRO 21-cubic-foot carrier, it’s more manageable but offers less capacity. Its universal fit makes it suitable for most roof racks, but verification is needed to ensure compatibility. Overall, this model suits families seeking a reliable, easy-to-access hard-shell carrier that fits most vehicles, with the understanding that it may need careful installation and longer-term durability review.
Pros:- Dual-sided opening for convenient access from either side
- Weather-resistant ABS shell keeps contents protected
- Universal fit with most roof racks enhances versatility
- Moderate capacity suitable for medium trips
Cons:- Customer rating below 4 stars raises durability questions
- Limited one-year warranty may impact long-term confidence
- Requires verification for specific roof rack compatibility
Best for: Families who prioritize easy access and broad roof rack compatibility without needing maximum capacity
Not ideal for: Heavy-duty travelers with frequent, heavy loads or those seeking the most durable long-term solution
- Material:ABS
- Capacity:12 Cubic Feet (340L)
- Weight Capacity:165 lbs
- Dimensions:54.3″L x 31.5″W x 13.4″H
- Color:Black
- Warranty:1 year
Our verdict“This cargo box is a solid choice for families needing flexible access and broad compatibility, but may require attention to durability and fit details.”
Rooftop Cargo Box, 15.5 Cubic Ft, Black
This 15.5-cubic-foot rooftop cargo box offers generous space ideal for larger families or those packing bulky gear, surpassing the 12-cubic-foot Garvee with its added capacity. Its dual-side access and three-point locking system ensure secure, straightforward loading, making it a practical upgrade for frequent travelers. The tool-free installation simplifies setup compared to bulkier models like the Thule Pulse 2, which may require more time to mount securely. However, its 130 lbs weight limit could restrict very heavy loads, and the absence of explicit noise reduction features might lead to increased road noise. This model suits families seeking extra capacity with easy setup, accepting some limitations on weight and noise considerations.
Pros:- Large 15.5 cubic feet capacity for bulky gear
- Easy, tool-free installation saves setup time
- Secure three-point locking for peace of mind
- Dual-side accessibility simplifies loading and unloading
Cons:- Limited to 130 lbs weight capacity
- Potential for increased noise during highway speeds
- No specific noise reduction features
Best for: Families needing maximum cargo space with quick, tool-free installation
Not ideal for: Travelers with very heavy gear or those sensitive to road noise, as it lacks specific noise mitigation features
- Capacity:15.5 cubic feet
- Weight Capacity:130 lbs
- Material:ABS plastic and PMMA
- Installation:Tool-free, universal mounting brackets
- Locking Mechanism:Three-point lock
- Color:Black
Our verdict“This spacious, easy-to-install cargo box is perfect for families prioritizing capacity and quick setup over maximum load weight and noise reduction.”
WORKPRO Rooftop Cargo Carrier Bag, 21 Cubic Feet Waterproof Car Roof Bag
The WORKPRO 21-cubic-foot waterproof roof bag offers the largest capacity among soft carriers, making it ideal for outdoor families with bulky or numerous items. Its 840D PVC fabric ensures excellent weather resistance, and the reinforced straps and safety features like reflective strips enhance security during long trips. Compared with hard-shell options like the Thule Pulse 2, this soft carrier provides more volume but less protection against impacts. Its flexible nature makes it easier to store when not in use, yet the waterproof performance might vary in extreme conditions, and it’s less stable on roof racks without proper securing. This makes it suitable for adventurers prioritizing maximum space and weatherproofing over rigid protection and structural integrity.
Pros:- Largest capacity at 21 cubic feet for bulky outdoor gear
- 100% waterproof, suitable for all weather conditions
- Easy to install with multiple straps and hooks
- Reflective strips enhance safety during night travel
Cons:- Less protective against impacts compared to hard-shell boxes
- Waterproof performance may vary in extreme weather
- Not suitable for attaching to side bars during installation
Best for: Outdoor-loving families needing maximum cargo space with weatherproof protection and flexible storage
Not ideal for: Those seeking rigid protection against impacts or traveling in extreme weather conditions where a hard shell is preferable
- Capacity:21 cubic feet
- Material:840D PVC
- Includes:6 safety hooks, 2 reinforced straps, 1 storage bag, user manual
- Dimensions:52″ x 40″ x 17″
- Waterproof:Yes
- Color:Black
Our verdict“This large, waterproof soft carrier is ideal for outdoor families needing maximum cargo space, accepting the tradeoff of less impact protection.”
Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Ft
The Thule Pulse 2 L offers a reliable 16 cubic feet of weather-resistant cargo space, making it a favorite for families wanting a durable, secure option. Its dual-side opening provides convenient access, similar to the Garvee but with a more rugged ASA-ABS shell that resists the elements effectively. Its tool-free installation system with torque indicators simplifies setup compared to larger, more complex models like the Thule Force XT. While its size may pose a challenge for smaller vehicles, it balances capacity with a sleek, aerodynamic profile that minimizes noise and drag. The limited color options and lack of detailed locking features might be drawbacks for some, but overall, it’s a dependable choice for those prioritizing security and weather protection.
Pros:- Large 16 cubic feet capacity for versatile family gear
- Easy, tool-free installation with torque indicator
- Weather-resistant ASA-ABS plastic withstands elements
- Dual-side access for convenient loading
Cons:- May be bulky for small or compact vehicles
- Limited color options
- No explicit mention of locking mechanism details
Best for: Families seeking a compact yet spacious, weather-resistant cargo box with simple installation and secure access
Not ideal for: Very small vehicles or those needing maximum capacity beyond 16 cubic feet, or requiring extensive color choices
- Capacity:16 Cubic Feet
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Access:Dual-side opening
- Dimensions:450 liters
Our verdict“This cargo box is ideal for families wanting a secure, weather-resistant container that’s easy to install and access, fitting most mid-sized vehicles.”
Rooftop Cargo Box, 15.5 Cubic Ft, for Family Travel and Road Trips, Grey
The Grey 15.5-cubic-foot rooftop cargo box offers a well-rounded solution for family trips, combining ample space with straightforward installation. Its durable ABS plastic and PMMA construction provide weather resistance, comparable to the Black version but with a slightly different aesthetic. Its three-point locking system enhances security, and dual-side access speeds up loading and unloading, similar to the other 15.5-cubic-foot models. Handling might be cumbersome for some due to weight, and installation requires compatible roof bars, but overall, it balances capacity, security, and ease of use effectively. This makes it an excellent choice for families who want a reliable, mid-sized cargo box that fits a variety of vehicles and gear.
Pros:- Weather-resistant durable construction
- Large capacity suitable for family gear
- Secure three-point locking system
- Dual-side accessibility for convenience
Cons:- Heavy to handle without assistance
- Requires compatible roof bars for installation
- May be cumbersome for small vehicles
Best for: Families looking for a reliable, weather-resistant cargo box with secure locking and easy access
Not ideal for: Travelers with very light or minimal gear who prefer smaller, more compact storage options
- Capacity:15.5 cubic feet
- Weight Capacity:130 lbs
- Material:ABS plastic and PMMA
- Color:Grey
- Installation:Tool-free, universal mounting brackets
Our verdict“This cargo box suits families wanting a secure, weatherproof storage solution that balances capacity with ease of access, provided the vehicle can handle its weight.”
Rooftop Cargo Box, 13 Cubic Ft, White
This cargo box stands out for its all-weather, impact-resistant construction, making it ideal for families who frequently travel in diverse conditions. Its 13 cubic feet capacity offers ample space without adding excessive bulk, and dual-sided access simplifies loading and unloading, especially when carpooling or traveling with kids. Compared with the SportRack Vista XL, which offers a larger 18 cubic feet capacity, this model is more manageable in terms of weight and installation. However, its white finish limits aesthetic options and may show dirt more readily. The secure three-point locking system ensures belongings stay safe during long trips, but installation could challenge beginners due to its weight and mounting process.
Pros:- Durable and weather-resistant construction
- Dual-sided access for easier loading
- Secure three-point locking system
- Impact-resistant materials
Cons:- Installation may require some effort for beginners
- Limited color options (only white)
- Potentially heavy for some users
Best for: Families seeking a durable, weatherproof cargo solution with straightforward access and reliable security.
Not ideal for: Travelers who prioritize maximum capacity over ease of installation or aesthetic variety, or those who prefer a wider range of color options.
- Capacity:13 cubic feet
- Material:Impact-resistant ABS plastic and PMMA
- Dimensions:56″ L x 30″ W x 13.7″ H
- Weight Capacity:130 lbs
Our verdict“This model suits families who want a reliable, durable cargo box with easy access, accepting some installation effort.”
Rooftop Cargo Box, 13 Cubic Ft, Black
This black cargo box provides the same 13 cubic feet of weather-resistant storage as the white model, but shines for its quick, universal mounting system, making it a better choice for frequent setup changes or less experienced users. Its dual-sided access and secure locking system mirror the white version, yet its quick-install brackets cut down on setup time significantly. Compared to the SportRack Vista XL, which offers more capacity, this model trades some extra space for portability and ease of installation. Limited color options and the absence of included mounting tools may be drawbacks for some buyers, particularly those lacking compatible crossbars. Overall, it makes the most sense for families who need a secure, weatherproof box that can be installed swiftly and often.
Pros:- Easy to access from both sides
- Quick, universal installation system
- Secure three-point locking system
- Weather-resistant and impact-resistant
Cons:- Limited color options (only black)
- May require checking crossbar compatibility
- No included mounting tools
Best for: Families who want a hassle-free, impact-resistant cargo box with quick setup for frequent use.
Not ideal for: Those needing maximum storage volume or a broader color palette, or who prefer including mounting tools with their purchase.
- Capacity:13 cubic feet
- Material:Impact-resistant ABS plastic and PMMA
- Dimensions:56″ L x 30″ W x 13.7″ H
- Weight Capacity:130 lbs
Our verdict“Ideal for families seeking a durable cargo box that installs rapidly and offers dual-side access without hassle.”
SportRack Vista XL Rear Opening Cargo Box
The SportRack Vista XL offers a generous 18 cubic feet of storage, making it the standout for families needing maximum space. Its rear opening design simplifies access, especially when the car is packed with passengers or gear, and the UV-resistant ABS material ensures long-term durability. Compared with the 13-cubic-foot options, it sacrifices some ease of installation due to its larger size and weight, which may be challenging for solo handling. Its tool-free mounting system simplifies setup, but it’s wise to double-check fit with your crossbars since compatibility varies. This box is best for large families or those with extensive gear, but it’s less suitable for smaller cars or users who prefer lightweight options.
Pros:- Large 18 cubic foot capacity
- Rear opening for convenient access
- Tool-free mounting for quick setup
- UV-resistant durable material
Cons:- May be heavy to handle alone
- Requires checking fit with specific roof rack systems
- Less suitable for compact cars
Best for: Families with substantial gear needs who prioritize maximum capacity and rear access for loading and unloading.
Not ideal for: Travelers with smaller vehicles or those who prefer lightweight, easier-to-handle cargo solutions, or who don’t need much space.
- Capacity:18 cubic feet
- Material:UV-resistant ABS
- Dimensions:63 x 38 x 19 inches
- Max Weight Capacity:100 pounds
Our verdict“Best suited for large families or those with extensive gear who need maximum storage and rear access convenience.”

Factors to Consider When Choosing Best Rooftop Cargo Box For Family Road Trips
Choosing the right rooftop cargo box for family road trips involves weighing several key factors. Beyond capacity, look for ease of installation, weatherproofing, and safety features that protect your gear and your vehicle. Additional considerations include aerodynamics to reduce wind noise and drag, as well as compatibility with your vehicle’s roof. Making the right choice involves understanding your specific needs, such as trip length, family size, and budget, to find a model that offers the best balance of features and value.Capacity and Size
Capacity is a primary factor, especially for family trips where packing large amounts of gear or bulky items like sleeping bags and tents is common. Larger boxes, typically over 15 cubic feet, provide more room but can increase wind resistance and fuel consumption. It’s important to measure your roof space and choose a size that fits without overhanging or causing instability. Consider your typical packing needs—if you often travel with multiple family members or bulky equipment, prioritize higher capacity options.
Ease of Installation and Access
Look for models that are straightforward to install and remove, especially if you plan to switch vehicles or store the box when not in use. Dual-side opening features enhance convenience, allowing access from either side of the vehicle without extra maneuvering. Clamps or quick-release mounting systems can save time and effort, but ensure they are compatible with your roof rack system. Avoid overly complex setups that may require professional installation unless you are comfortable with tools and assembly.
Weatherproofing and Durability
Since family trips often involve unpredictable weather, waterproof shells and sturdy construction are essential. High-quality materials prevent water ingress and resist UV damage, ensuring your gear stays dry and protected over multiple trips. Check for reinforced seams and secure locking mechanisms that enhance security and weather resistance. A durable build also means the box can withstand road debris and minor impacts without cracking or breaking.
Aerodynamics and Noise
Roof-mounted boxes can increase wind noise and drag, which impacts fuel efficiency and driving comfort. Opt for streamlined designs that minimize air resistance—these tend to produce less noise and improve mileage. If you frequently drive long distances, investing in a more aerodynamic model can make a noticeable difference in your overall trip experience. Keep in mind that larger, boxy designs may be more prone to creating noise and turbulence.
Compatibility and Fit
Ensure the cargo box fits your vehicle’s roof rack system, whether it’s bars, rails, or tracks. Universal fit models are flexible but double-check weight limits and mounting options. Overloading the roof can compromise safety and handling, so choose a box with a weight capacity suited for your gear and vehicle. Consider the ease of opening from either side if parking in tight spots is common during your trips.
Frequently Asked Questions
How do I know if a rooftop cargo box will fit my vehicle?
Checking your vehicle’s roof dimensions and comparing them with the cargo box’s dimensions is essential. Most models specify maximum roof width and length, and some are designed to be adjustable for different roof types. Measure your roof rack’s crossbars or rails, and verify that the box’s mounting system is compatible. If in doubt, many manufacturers offer fit guides or customer support to help you confirm compatibility before making a purchase.
What is the best capacity for a family road trip cargo box?
The ideal capacity depends on your family size and gear volume, but generally, 15 to 18 cubic feet provides ample space for most family needs. Larger options, such as 20+ cubic feet, are suitable if you pack bulky items or plan extended trips. Avoid overly large boxes if your vehicle’s roof can’t support the weight or if aerodynamics and fuel economy are concerns. Matching capacity to your typical packing list ensures comfort without unnecessary bulk or expense.
Are rooftop cargo boxes secure against theft?
Many models include locking mechanisms that secure your gear and deter theft, but the level of security varies. Look for boxes with keyed locks or electronic locking systems if security is a priority. Additionally, consider installing anti-theft devices or using a cable lock for added protection, especially if you plan to leave your vehicle unattended during stops. Remember that no lock is foolproof, so choose a reputable brand with reliable locking features.
How does wind resistance affect fuel efficiency, and can I minimize it?
Roof cargo boxes increase wind resistance, which can lead to higher fuel consumption, especially over long distances. To mitigate this, choose aerodynamic designs with smooth contours and low profile shapes. Properly securing the box to prevent movement also reduces turbulence. If fuel economy is a concern, consider removing the box when not in use or opting for a smaller, more streamlined model for daily trips.
Is it safe to overload a rooftop cargo box?
Overloading a cargo box compromises both safety and durability. Exceeding the manufacturer’s weight limit can cause structural failure or damage to your vehicle’s roof rack. It also affects handling and braking, especially during emergency maneuvers. Always check the maximum weight capacity and distribute weight evenly inside the box. When in doubt, opt for a larger, stronger model or reduce the amount of gear packed to stay within safe limits.
Conclusion
For families seeking a reliable, all-around solution, the Thule Force XT offers a balanced mix of capacity, durability, and ease of use, making it the best overall choice. Budget-conscious travelers will appreciate the GarveeTech Rooftop Cargo Box for its capacity at a more affordable price point. Those looking for premium features and top-tier durability should consider the Thule Motion 3, especially for frequent travelers. Beginners and casual users benefit from models with simple installation and access, while larger families or those packing bulky gear may prioritize high capacity and weatherproofing. Matching your specific needs to these options will help ensure your family trips are smooth and enjoyable.
