More Details on Our Top Picks

  1. Thule Force 3 XL Cargo Box

    Thule Force 3 XL Cargo Box

    Best Overall for Durability and Ease of Access

    View on Amazon

    The Thule Force 3 XL stands out for its robust durability and versatile design, making it an excellent choice for frequent travelers who need reliable storage. Its quick, secure mounting system with safety indicators simplifies installation, especially compared to the more cumbersome setup of the Garvee Heavy Duty Carrier. This cargo box offers easy access from both sides, enhancing convenience during stops. However, its size and weight can pose challenges when installing solo, and the limited color options may not suit all aesthetic preferences. Compared to the Thule Motion 3, it provides more capacity and a more straightforward mounting process, but it is slightly heavier and less aerodynamic. Overall, this makes sense for users prioritizing durability, safety, and easy loading, even if it requires some effort to handle.

    Pros:
    • Durable and sleek design suitable for daily use
    • Easy and secure mounting system with safety indicators
    • Provides convenient access from both sides
    Cons:
    • May be large and heavy to install alone
    • Limited color options

    Best for: Active families or outdoor enthusiasts who need a durable, high-capacity cargo solution for frequent use

    Not ideal for: Single travelers or those with limited lifting capacity, due to its size and weight

    • Capacity:up to 16 cubic feet
    • Material:Durable plastic
    • Mounting System:Quick, secure, and intuitive
    • Locking System:SlideLock with separate locking and opening functions
    Our verdict
    “This cargo box is best suited for users prioritizing durability, security, and dual-side access, willing to handle its weight.”
  2. Rooftop Cargo Carrier for Car Storage 11 Cubic Ft 110 Lb Capacity

    Rooftop Cargo Carrier for Car Storage 11 Cubic Ft 110 Lb Capacity

    Best Value for Weatherproof, Aerodynamic Storage

    View on Amazon

    This 11 cubic foot carrier offers a balance of capacity and affordability, making it a versatile choice for those with cross bars on their vehicle. Its impact-resistant ABS plastic construction provides weatherproof protection, rivaling the durability of pricier options like the Garvee Heavy Duty Carrier. The aerodynamic shape helps reduce fuel consumption and noise, which is a significant advantage over bulkier hard-shells. However, it requires cross bars for mounting, which can be a compatibility hassle, and the 110 lb weight limit may restrict heavier gear. Unlike the larger capacity of the Thule Force 3 XL, it’s more suitable for moderate loads and smaller vehicles. This pick makes the most sense for budget-conscious travelers who want weatherproof security without sacrificing aerodynamics.

    Pros:
    • Spacious 11 cubic feet capacity for extra storage
    • Weatherproof and impact-resistant construction
    • Includes security lock for valuables
    Cons:
    • Requires cross bars for installation, verify compatibility
    • Maximum load capacity may limit heavy gear
    • Hard shell design may be less flexible than soft bags

    Best for: SUV or crossover owners seeking a weatherproof, cost-effective storage solution with moderate capacity

    Not ideal for: Those with incompatible roof rack setups or needing to carry very heavy loads, due to mounting and capacity limits

    • Capacity:11 cubic feet
    • Max Load:110 lbs
    • Dimensions:53″L x 34″W x 15″H
    • Material:ABS plastic
    Our verdict
    “This carrier offers a smart combination of weatherproof durability and aerodynamic design for moderate road trip needs on compatible vehicles.”
  3. Garvee Heavy Duty Hard Shell Roof Top Cargo Carrier – 69″ x 33″ x 11″

    Garvee Heavy Duty Hard Shell Roof Top Cargo Carrier - 69" x 33" x 11"

    Best for Large, Waterproof Capacity with Security

    View on Amazon

    The Garvee Heavy Duty Carrier excels in offering a sizable 17 cubic feet of waterproof storage, making it ideal for outdoor adventures and camping trips. Its rugged design and UV-resistant coating ensure durability across diverse weather conditions. Dual-sided access with lockable security adds convenience and safety, especially when compared to softer or less secure options like the Thule Pulse 2. The main tradeoff involves handling its weight and bulkiness, which can be challenging for some users, and it requires roof rack compatibility. While it provides ample capacity and waterproofing, its size may limit accessibility on smaller or lower-profile vehicles. This product makes sense for those who need maximum waterproof storage with security, even if it’s less nimble to install and handle.

    Pros:
    • Large 17 cu ft capacity for ample gear
    • Waterproof and UV-resistant for durability
    • Easy, tool-free installation
    Cons:
    • May be bulky to handle for some users
    • Requires roof rack compatibility
    • Limited color options

    Best for: Outdoor enthusiasts needing a large, waterproof, lockable cargo solution for rugged environments

    Not ideal for: Urban drivers with limited roof rack space or those seeking lightweight options, due to bulk and handling difficulty

    • Dimensions:69″L x 33″W x 11″H
    • Capacity:17 Cu Ft
    • Weight Capacity:165 Lb
    • Material:ABS plastic with UV-resistant coating
    Our verdict
    “This cargo carrier is best for users prioritizing waterproof, secure, and large capacity storage for outdoor adventures.”
  4. Thule Motion 3 Rooftop Box

    Thule Motion 3 Rooftop Box

    Best for Aerodynamics and Fuel Efficiency

    View on Amazon

    The Thule Motion 3 features a sleek, wing-shaped profile that helps reduce drag, making it an excellent choice for drivers conscious of fuel economy. Its sturdy lid with a wide handle simplifies opening and closing, especially compared to bulkier models like the Garvee Carrier. The inclusion of interior lighting, a protective liner, and a storage cover adds convenience and protection, though the lack of specific capacity details leaves some uncertainty about its size. The PowerClick quick-mount system with torque indicator ensures secure, straightforward installation. However, the limited info on vehicle compatibility and capacity may make it less ideal for heavier loads or complex setups. This makes it a good fit for road trippers aiming for aerodynamics without sacrificing key features.

    Pros:
    • Aerodynamic design improves fuel efficiency
    • Easy to install with quick-mount system
    • Secure locking with visual indicator
    Cons:
    • No specific capacity or size details provided
    • Limited information on vehicle compatibility
    • Potentially less suitable for very heavy loads

    Best for: Drivers seeking a stylish, aerodynamic cargo box that enhances fuel efficiency on long trips

    Not ideal for: Those needing detailed size and capacity specs or with complex vehicle setups, as compatibility info is sparse

    • Design:Wing-shaped profile for reduced drag
    • Handle:Wide handle for smooth operation
    • Accessories:Interior box light, protective liner, storage cover
    • Mounting System:PowerClick quick-mount with torque indicator
    Our verdict
    “This cargo box is ideal for road trippers prioritizing sleekness and fuel savings over maximum capacity details.”
  5. 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 Large Capacity and Easy Access

    View on Amazon

    The Thule Pulse 2 L offers a substantial 16 cubic feet of storage, making it perfect for families or travelers with bulky gear. Its dual-side opening allows for quick access from either side, which is a major convenience compared to top-only access models like the Rooftop Carrier for Car Storage. The weather-resistant ASA-ABS plastic ensures durability against the elements, and the tool-free, secure attachment system simplifies installation. However, limited compatibility with roof types and potential difficulty reaching items on certain vehicle configurations might reduce its practicality. Compared with the larger, more rugged Garvee Carrier, it provides a balance of capacity and ease of use, making it suitable for a wide range of road trip setups.

    Pros:
    • Large cargo capacity suitable for various gear
    • Easy, tool-free installation with secure attachment
    • Weather-resistant and durable material
    Cons:
    • Limited to roof-mounted installation
    • May be challenging to access from certain vehicle configurations
    • Less rugged than some hard-shell alternatives

    Best for: Families or casual travelers needing a large, easy-to-access cargo box for general road trips

    Not ideal for: Drivers with complex or low-clearance roof setups, or those needing maximum waterproofing, as it’s more suited for accessible yet moderate conditions

    • Capacity:16 cubic feet
    • Load Capacity:75 kg
    • Material:ASA-ABS plastic
    • Access:Dual-side opening
    Our verdict
    “This cargo box is best for families or casual users seeking large capacity with straightforward dual-side access on compatible vehicles.”
  6. TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys, Waterproof Hard Shell Travel Roof Storage Carrier, 61″ L x 27.6″ W x 13.8″ H, Dual-Side Opening, for SUV, Car, Van, Black

    TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys, Waterproof Hard Shell Travel Roof Storage Carrier, 61" L x 27.6" W x 13.8" H, Dual-Side Opening, for SUV, Car, Van, Black

    Best Overall for Versatile Weather Protection and Security

    View on Amazon

    This cargo box stands out for its combination of weatherproof durability and user-friendly dual-side access, making loading and unloading straightforward from either side of the vehicle. Its secure lock system with keys adds peace of mind, especially when parked in busy areas. Compared to the SportRack Vista XL, which offers a larger capacity but less weather resistance, the TUFFIOM’s waterproof ABS shell ensures belongings stay dry in heavy rain. However, its installation requires compatible crossbars with specific width and spacing, which might limit some vehicles. Its sleek, streamlined design also reduces wind noise and drag, improving overall efficiency during travel. This pick makes the most sense for drivers seeking a balanced mix of weather protection, security, and ease of access.

    Pros:
    • Easy dual-side access for loading and unloading
    • Secure locking system with keys for safety
    • Durable ABS material protects against weather
    • Reduces wind noise and drag
    Cons:
    • Requires specific crossbar width and spacing for installation
    • Peeling protective film needs removal before use

    Best for: SUV owners who need reliable weatherproofing and security for frequent road trips

    Not ideal for: Drivers with non-standard crossbar setups or very limited installation space

    • Capacity:13.4 cubic feet
    • Dimensions:61″ L x 27.6″ W x 13.8″ H
    • Weight:24.25 lbs
    • Material:ABS
    • Max Crossbar Width:2.36″
    • Max Installation Distance:40.94″
    • Locking System:Locks with keys
    • Warranty:3 years
    Our verdict
    “Ideal for SUV drivers prioritizing weatherproof security and convenient access during extended road trips.”
  7. GarveeTech Rooftop Cargo Box Carrier, 165 LBS Capacity, Dual-Side Opening, Waterproof, UV-Resistant, Black

    GarveeTech Rooftop Cargo Box Carrier, 165 LBS Capacity, Dual-Side Opening, Waterproof, UV-Resistant, Black

    Best Value for Large Capacity and Universal Fit

    View on Amazon

    Compared with the SportRack Vista XL, which offers the largest capacity among these options, the GarveeTech provides a slightly smaller 12 cubic feet but favors durability and UV resistance with its ABS shell. Its dual-sided opening makes access convenient, especially on longer trips, while its universal mounting system fits most roof racks, broadening its appeal. Still, the limited 30-day warranty might be a concern for buyers seeking long-term assurance. Unlike the TUFFIOM, which requires specific crossbar widths, GarveeTech’s compatibility is more flexible, but it demands a roof rack for installation. This model is better suited for budget-conscious travelers who value durability and straightforward fit over a longer warranty period.

    Pros:
    • Waterproof and UV-resistant ABS construction
    • Large 12 cubic feet storage capacity
    • Dual-sided opening for easy access
    • Universal roof rack compatibility
    Cons:
    • Limited to 30-day warranty
    • Requires roof rack for installation

    Best for: Budget-conscious families seeking a durable, UV-resistant cargo box with broad vehicle compatibility

    Not ideal for: Owners of vehicles without compatible roof racks or those wanting extended warranty coverage

    • Capacity:12 cubic feet
    • Weight Capacity:165 LBS
    • Dimensions:54.3 in L x 31.5 in W x 13.4 in H
    • Material:ABS plastic
    • Color:Black
    • Mounting Type:Roof mount
    Our verdict
    “A solid choice for users needing reliable, weatherproof capacity with universal mounting and good value.”
  8. Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box

    Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box

    Best for Simplicity and Heavy Load Capacity

    View on Amazon

    This universal cargo box emphasizes straightforward, weather-resistant storage with its durable ABS plastic shell and a 110 lbs weight limit. Its large capacity suits travelers with bulky gear, and the secure lock adds peace of mind. Compared to the Auto Dynasty model, which offers slightly less volume but more precise dimensions, this box is easier to mount on vehicles with standard cross bars, thanks to its simple design. However, it only fits vehicles with cross bars and might require additional tools for installation, which could be a hurdle for DIYers. Its ample space and robust build make it well-suited for those who prioritize capacity and weather resistance over complex features or sleek aerodynamics.

    Pros:
    • Durable and weather-resistant ABS construction
    • Easy to install on vehicles with cross bars
    • Secure lock for added security
    • Large 110 lbs capacity
    Cons:
    • Fits only vehicles with cross bars
    • May require additional tools for installation

    Best for: Travelers needing a straightforward, weatherproof cargo solution with high load capacity

    Not ideal for: Owners of vehicles without cross bars or those seeking sleek, aerodynamic designs

    • Material:ABS plastic
    • Capacity:110 lbs
    • Dimensions:53 x 34 x 15 inches
    • Color:Black textured surface
    • Includes:Cargo roof box, keys, mounting brackets and hardware
    Our verdict
    “Best for users who want a rugged, high-capacity cargo box that’s straightforward to install on compatible vehicles.”
  9. Auto Dynasty Hard Shell Roof Top Mount Cargo Carrier

    Auto Dynasty Hard Shell Roof Top Mount Cargo Carrier

    Best for Family and Outdoor Enthusiast Use

    View on Amazon

    This cargo box offers 11 cubic feet of space with a focus on ease of loading, featuring a wide 14-inch opening that simplifies packing large or awkward items. Its impact-resistant ABS shell provides reliable weather protection, making it suitable for outdoor adventures and family trips. Compared with the GarveeTech box, which has a slightly larger capacity, the Auto Dynasty’s wider opening enhances convenience for bulky gear. Its universal fit with up to 13-inch wide crossbars broadens compatibility, though installation may be tricky without assistance, particularly for solo travelers. This model makes the most sense for those who prioritize quick access and a secure, weatherproof environment for family travel gear.

    Pros:
    • Spacious 11 cubic feet capacity
    • Wide 14-inch opening for easy loading
    • Weather-resistant, impact-protected ABS shell
    • Secure lock system
    Cons:
    • Requires checking crossbar width for compatibility
    • May be difficult to install alone

    Best for: Families and outdoor enthusiasts needing quick, wide access for bulky or multiple items

    Not ideal for: Solo travelers or those with non-standard crossbar sizes who prefer simpler mounting

    • Dimensions:53″ L x 34″ W x 15″ H
    • Capacity:11 Cubic Feet
    • Weight Limit:110 lbs
    • Material:UV-protected, weather-resistant ABS
    • Opening Width:14 inches
    • Mounting Compatibility:Max 13 inches wide cross bar
    Our verdict
    “Ideal for families and outdoor lovers seeking easy access and secure weatherproof storage for bulkier gear.”
  10. SportRack Vista XL Rear Opening Cargo Box

    SportRack Vista XL Rear Opening Cargo Box

    Best for Maximum Capacity and Easy Rear Access

    View on Amazon

    The SportRack Vista XL stands out with its impressive 18 cubic feet of storage, ideal for large families or those needing maximum space. Its rear-opening design simplifies access, especially when parked in tight spots, and the tool-free mounting system allows quick setup. Compared to the TUFFIOM, which offers weatherproof protection but less capacity, the Vista XL prioritizes volume, though it is heavier at 100 pounds, making handling more challenging. Its UV-resistant ABS shell ensures durability against the elements, but its limited color options and weight may deter some users. This carrier is best suited for travelers who prioritize maximum storage and easy access over ease of handling or aesthetic variety.

    Pros:
    • Large 18 cubic feet capacity
    • Rear opening for easy access
    • Tool-free installation
    • UV-resistant ABS construction
    Cons:
    • Heavy at 100 pounds, difficult to handle alone
    • Limited color options

    Best for: Large families or groups needing maximum cargo space with convenient rear access

    Not ideal for: Solo travelers or those with difficulty handling heavy equipment

    • 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
    “Best for users demanding maximum cargo volume and simple rear access for large loads during trips.”

Factors to Consider When Choosing Rooftop Cargo Box For Road Trips

Choosing the right rooftop cargo box involves considering several key factors that affect both usability and safety. Beyond capacity, aspects like installation ease, weather protection, and security are critical. Understanding these broader considerations can help avoid common pitfalls like overloading or selecting a model incompatible with your vehicle. Here are the main points to keep in mind when selecting a cargo box for road trips.

Capacity and Size

Capacity determines how much gear you can carry, but larger boxes tend to be heavier and may impact your vehicle’s handling. Measure your roof and consider your vehicle’s weight limits—overloading can compromise safety and fuel efficiency. Think about your trip length and the amount of gear needed; a smaller box might suffice for short trips, while longer journeys with family gear benefit from larger capacities. Avoid choosing a box that’s too big for your vehicle or one that forces you to overpack beyond safe limits.

Ease of Installation and Access

Look for models that are straightforward to mount and remove, especially if you plan to switch between vehicles or store the box when not in use. Dual-side opening features make loading and unloading easier, particularly when your vehicle is parked close to other cars or obstacles. Consider how many people will need to access the contents regularly; a difficult-to-open or awkwardly placed latch can be frustrating on long trips. Remember, a well-designed cargo box saves time and reduces hassle during stops.

Weatherproofing and Durability

Since road trips often involve exposure to rain, snow, and sun, selecting a weatherproof model is vital. Hard-shell containers with sealed edges and waterproof materials prevent moisture from seeping in. UV resistance adds longevity, preventing cracking and fading over time. Cheaper options may lack proper seals, risking damage to your gear. Investing in a durable, waterproof cargo box can protect your belongings and ensure they stay dry through changing weather conditions.

Material and Build Quality

Most rooftop cargo boxes are made from ABS or polycarbonate plastics, each with pros and cons. Heavy-duty materials tend to be more resistant to impacts and weather but may add weight. A sturdily constructed box offers better protection but could be more challenging to handle and install. Weighing the tradeoff between durability and weight is key, especially if you plan frequent use or need to lift the box onto the roof regularly. Cheaper models may sacrifice build quality, leading to quicker wear or failure.

Security Features

Lockable lids are essential for safeguarding belongings, especially when parking in unfamiliar areas. Consider models with integrated locks or padlock compatible systems, which deter theft and prevent accidental opening. Keep in mind that some lock mechanisms are easier to operate than others; smooth, sturdy locks reduce frustration during frequent stops. Security should be balanced with ease of access—overly complex locking systems may slow down loading or unloading when in a hurry.

Frequently Asked Questions

How do I know if a rooftop cargo box fits my vehicle?

Start by measuring your vehicle’s roof width and cross-referencing with the cargo box dimensions. Check your vehicle’s roof weight limit to ensure it can support the combined weight of the box and your gear. Many manufacturers provide compatibility guides or vehicle fit lists, which can simplify the process. If your vehicle has roof rails or crossbars, verify that the mounting system of the cargo box is compatible or consider additional accessories. Proper fit is crucial for safety and stability during travel.

Is a larger capacity cargo box worth the extra cost?

A larger capacity can be very beneficial for long trips or when traveling with family and bulky gear, making the extra investment worthwhile. However, bigger boxes tend to be heavier and may affect your vehicle’s fuel economy and handling. They also require more effort to install and remove. If your trips are typically short or involve minimal gear, a smaller, more manageable box might offer better overall value and ease of use. Assess your typical luggage needs before opting for maximum capacity.

What features should I prioritize for frequent use?

For frequent trips, focus on durability, ease of access, and security. A robust, weatherproof shell will protect your gear through various conditions, while dual-side opening simplifies loading and unloading. Locking mechanisms are essential for peace of mind, especially if you park in public areas often. Also, look for lightweight yet sturdy materials to make installation easier without sacrificing protection. These features help ensure your investment remains convenient and reliable over time.

Are soft-sided cargo carriers a good alternative?

Soft-sided carriers are generally lighter and easier to store when not in use, but they typically offer less protection against weather and impacts. They can be more flexible in fitting irregular roof shapes but may not hold as much weight or volume as hard-shell options. For long-term durability and security, especially in rough weather, hard-shell cargo boxes tend to be more dependable. Soft-sided options can work well for short trips or casual use, but they often lack the security features found in hard shells.

How much does a rooftop cargo box typically add to my vehicle’s weight?

Most cargo boxes weigh between 25 to 50 pounds, with larger or more robust models leaning toward the higher end. It’s important to factor this weight into your vehicle’s roof load capacity, including the weight of your gear. Overloading can affect handling, braking, and safety, so always verify your vehicle’s maximum roof weight limit. Choosing a lighter model can make installation easier and help maintain optimal driving performance, especially on long or mountainous routes.

Conclusion

For general road trip use, the Thule Force 3 XL offers the best combination of capacity, durability, and ease of use, making it the ideal choice for most travelers. Budget-conscious buyers should consider the Rooftop Cargo Carrier 11 Cubic Ft, which provides reliable performance at a lower price point. Those seeking premium features and maximum security may prefer the Garvee Heavy Duty Hard Shell, designed for rugged conditions. For beginners or infrequent travelers, lightweight and simple models like the SportRack Vista XL deliver straightforward functionality. Ultimately, your choice should align with your trip length, gear volume, and how often you plan to travel, ensuring safety and convenience on every journey.
