Its impact-resistant ABS and PMMA construction stand up well to the rigors of travel, comparable to the Thule Motion 3, but at a more accessible price point. Dual-sided access simplifies loading and unloading, especially when managing multiple family members. The secure three-point lock system enhances safety, though installation might require some adjustments depending on your vehicle’s crossbars.

Rough Country Rooftop Cargo Box 14.5 Cu Ft
The Rough Country 14.5 Cu Ft cargo box offers the largest volume among these options, making it ideal for families who need extensive storage. Its UV-protected ABS shell ensures weatherproofing, similar to the GarveeTech, but with a focus on maximum capacity. The strut-assisted lid simplifies loading even when the box is fully packed, a real advantage for larger families or gear-heavy trips. It installs easily on most crossbar systems without drilling, which is a plus. However, it’s heavier when loaded, and limited color options might affect aesthetic preferences. This model suits families prioritizing capacity over sleekness or lightweight design.
Pros:- Largest capacity at 14.5 cubic feet
- Weatherproof, UV-protected construction
- Strut-assisted lid for easy loading
- No-drill installation fits most crossbars

Rooftop Cargo Carrier Hard Shell, 13 Cubic Feet, Gray
This cargo box stands out for its solid balance of capacity and security, making it ideal for families who need enough space without complicating installation. Its sturdy ABS and PMMA construction offers weather resistance, and dual anti-theft locks add peace of mind. Compared to the Yakima SkyBox NX 18 XLG, this model has a slightly smaller capacity but is easier to install and handle, especially for those new to roof cargo systems. The support arm simplifies access, but the lock system’s design means locks can only be removed when fully closed—something to consider if quick access is a priority. It’s best suited for families who want reliable security and straightforward use, though it requires careful measurement to fit diverse roof racks.
Pros:- Large 13 cubic feet capacity for family gear
- Weather-resistant and durable construction
- Dual anti-theft locks for added security
- Support arm makes side access easier
Cons:- Locks can only be removed when fully closed
- Installation may be challenging for beginners
Best for: Families seeking a secure, weather-resistant cargo box with straightforward installation and moderate capacity.
Not ideal for: Those with very limited roof space or needing maximum capacity might find it too small compared with the Yakima SkyBox 18.
- Material:ABS and PMMA
- Capacity:13 cubic feet
- Weight Capacity:130 lbs
- Locking System:Dual anti-theft locks
- Opening Width:13.78 inches
- Max Cross Bar Width:3 inches

Our verdict“This model is well-suited for families prioritizing security and weatherproofing without demanding the largest capacity.”
Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Feet
The Thule Pulse 2 L earns a spot for its user-friendly dual-side opening, making loading and unloading more convenient, especially for larger families with multiple gear sets. Its 16 cubic feet capacity offers ample room, comparable to the Yakima SkyBox but with a more streamlined shape that fits well on many vehicles. The tool-free mounting system with a torque indicator adds confidence in secure attachment, but the 75 kg (165 lbs) load limit could be restrictive for heavy gear. Unlike the more robust Yakima, this box is better suited to moderate loads and lighter trips, making it ideal for families prioritizing ease of use over maximum capacity.
Pros:- Dual-side opening for easy access
- Tool-free mounting with torque indicator
- Weather-resistant and durable construction
- Secure attachment to roof racks
Cons:- Limited to 75 kg (165 lbs) load capacity

- Dimensions:450 liters of cargo space
Our verdict“This cargo box is ideal for families seeking convenient dual access and straightforward mounting for moderate loads.”
Thule Force 3 L Roof Cargo Box
The Thule Force 3 L is designed for active families who want a secure, reliable cargo solution. Its sleek appearance and extensive safety testing make it a strong choice, especially compared to basic models like the Garvee. The SlideLock system provides clear locking indicators and separate locking and opening functions, adding an extra layer of security. While its capacity is limited—designed for smaller loads—it excels in security and safety, making it perfect for families who prioritize peace of mind on outdoor adventures. If you need maximum volume, this may not be the best fit, but for those valuing safety and ease of use, it’s a compelling option.

Our verdict“This is a great choice for active families prioritizing safety, durability, and ease of access over maximum volume.”
Yakima SkyBox NX 18 XLG Rooftop Cargo Carrier, 18 Cu Ft, SKS Lock, Black
The Yakima SkyBox NX 18 XLG offers the largest capacity at 18 cubic feet, making it perfect for families with extensive gear needs, such as skis, snowboards, or multiple suitcases. Its dual-sided access simplifies loading from either side of the vehicle, a feature that sets it apart from smaller boxes like the Thule Force 3 L. The SKS lock adds security, while its sleek black design complements modern vehicles. The main tradeoff is its weight—heavier to install alone—and limited color options.

The Garvee Heavy Duty Cargo Carrier stands out for its waterproof construction and large 17 cubic feet capacity, making it a solid choice for outdoor families who face unpredictable weather. Its aerodynamic design helps reduce wind noise, a feature often overlooked but valuable during long drives. Compared with the Thule Force 3 L, this carrier supports a higher weight limit of 165 lbs, suitable for heavier gear or multiple family members’ belongings. Its UV-resistant coating ensures durability, but the challenge lies in its weight—potentially difficult to install solo—and limited color options. This model is best for families who prioritize waterproof security and heavy-duty performance over sleek aesthetics.

Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box
This cargo box stands out due to its durable ABS plastic construction, offering a combination of weather resistance and security. Unlike the larger capacity Goplus Rooftop Cargo Carrier with 14 cubic feet, this box provides a more compact yet still substantial support of 110 lbs, making it easier to handle and install on vehicles with cross bars. Its lockable lid enhances security, a key feature for family trips where valuables need safeguarding. The tradeoff is that it only fits vehicles equipped with cross bars, limiting compatibility compared to some universal models like the Goplus. Additionally, its weight and lack of insulation could pose challenges during installation or noise during travel, but overall, it offers a reliable balance of durability and security for families prioritizing weatherproofing and ease of use.
Pros:- Durable, weather-resistant ABS plastic construction
- Secure lock for valuables during travel
- Supports up to 110 lbs, ample for most family gear

Our verdict“This pick is ideal for families wanting a durable, weatherproof cargo box that installs easily on cross bars and provides secure storage.”
Goplus Rooftop Cargo Carrier Hard Shell, 14 Cubic Feet Waterproof Car Roof Cargo Box
The Goplus Rooftop Cargo Carrier offers a generous 14 cubic feet of storage, making it a strong choice for larger families or those carrying bulky gear. Compared with the Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box, which provides a more compact support of 110 lbs, the Goplus’s 165 lbs weight capacity allows for heavier loads, ideal for longer trips or when packing heavier items. Its dual-side opening enhances access, especially useful when multiple family members need to grab items quickly. However, it requires a compatible vehicle with racks between 17” and 22.8” wide, so it’s less suited for smaller or rackless vehicles. The installation can be a bit fiddly, needing careful alignment, and it cannot open both sides simultaneously, which may slow access during busy trips. Still, its waterproof design and security features make it a practical choice for larger loads.
Pros:- Large 14 cubic feet capacity for bulky gear
- Waterproof and durable ABS and PC construction
- Dual-side opening for quick access
- Supports up to 165 lbs, suitable for heavier loads
Cons:- Requires specific vehicle racks for installation
- Cannot open both sides at once, limiting convenience
- Installation may be tricky for some users
Best for: Families with larger cargo needs who have rack-equipped vehicles and prioritize easy access and waterproofing
Not ideal for: Drivers without compatible racks or those seeking a lightweight, minimalistic carrier
- Capacity:14 Cubic Feet
- Material:ABS and PC
- Weight Capacity:165 lbs

- Support:Support arm
Our verdict“This model suits families needing spacious, waterproof cargo with easy access, provided their vehicle has compatible racks.”
How We Picked
To determine the best roof cargo boxes for family road trips, I evaluated each product based on capacity, ease of installation and access, durability, weather resistance, security features, and overall value. I prioritized models that offer ample space for family gear while remaining manageable to install and load. Cost-effectiveness was also a factor, ensuring options appeal across different budgets. The ranking reflects a balance of these factors, highlighting products that provide the best combination of practicality, durability, and value for family travelers.Factors to Consider When Choosing Best Roof Cargo Box For Family Road Trips
Choosing the right roof cargo box involves weighing several important factors to match your family’s specific needs. Beyond capacity, consider how easy it is to load and unload, especially if you’re handling multiple children or bulky gear. Durability and weather resistance protect your belongings from rain and snow, while security features prevent theft. Size compatibility with your vehicle is also essential to avoid overloading or improper fit. Finally, think about your budget and which features deliver the best value for long-term family trips.Capacity and Size
Capacity determines how much gear you can carry, so choose a size that comfortably fits all your family’s essentials without overloading your vehicle. Larger models provide more space but can be heavier and more challenging to mount. Measure your vehicle’s roof and compare it with the cargo box dimensions to avoid compatibility issues. Remember, a box that’s too big may impact your vehicle’s aerodynamics and fuel efficiency.
Ease of Installation and Access
Look for models with straightforward mounting systems that fit your vehicle and allow quick installation, especially if you plan to swap between cars or install frequently. Dual-side opening enhances convenience, making it easier to access gear from either side without repositioning the vehicle. Consider whether the box has features like quick-release mounts or integrated locks to save time and improve security during stops.
Durability and Weather Resistance
Since family trips often involve unpredictable weather, choose a cargo box made from high-quality, UV-resistant, and waterproof materials. Hard-shell designs typically provide better protection against rain, snow, and debris, ensuring your gear stays dry. Also, check reviews for reports of cracking or fading over time, especially if you travel frequently or in harsh climates.
Security Features
Locks are essential if you plan to leave your vehicle unattended at rest stops or tourist spots. Models with integrated locking mechanisms prevent theft and unauthorized access, adding peace of mind. Keep in mind that some locks are more user-friendly than others, so consider the ease of locking and unlocking, especially when handling family gear or bulky items.
Budget and Value
While premium models often offer extra features and larger capacities, there are many budget-friendly options that deliver solid performance for family trips. Balance your budget against the features you value most—such as capacity, security, and weather resistance. Sometimes, spending a little more upfront on a durable, secure, and spacious box pays off in the long run through fewer repairs and replacements.
Frequently Asked Questions
How do I ensure my roof cargo box fits my vehicle?
Before purchasing, measure your roof’s dimensions and check the cargo box specifications for compatibility. Many manufacturers provide vehicle fit guides that can help you determine whether the box will fit your roof rails or crossbars. Also, consider the overall height of your vehicle with the box installed to ensure it fits in parking garages or under low-clearance structures. Proper mounting is crucial for safety and stability during travel.
Are lockable roof boxes worth the extra cost?
Lockable roof boxes offer added security, which is especially valuable if you frequently leave your vehicle unattended in public areas. They help prevent theft of your gear and provide peace of mind during stops. While they may add to the initial cost, the protection they offer can save you money and hassle in the long run, particularly on longer trips or in busy locations.
What is the best size capacity for a family road trip?
The ideal capacity depends on your family size and gear needs, but generally, a box with 12 to 18 cubic feet offers a good balance of space without overburdening your vehicle. Larger families or those bringing bulky gear like camping equipment may prefer models closer to 18 cubic feet. Consider how much gear you typically carry on trips and select a size that leaves some room for unexpected items or additional purchases.
How important is aerodynamics when choosing a cargo box?
Design and aerodynamics affect your vehicle’s fuel efficiency and driving stability, especially on long trips. Streamlined shapes reduce wind resistance and noise, making your drive quieter and more economical. While larger, boxy models maximize space, they may create more drag. Look for models with aerodynamic profiles if fuel economy and noise are priorities for your family’s trips.
Can I install a roof cargo box myself, or should I hire a professional?
Most roof cargo boxes are designed for DIY installation with simple tools and clear instructions, making them accessible for most vehicle owners. Proper installation is vital for safety, so take your time to follow the manufacturer’s guidelines and double-check your work. If you’re unsure about compatibility or mounting procedures, consulting a professional installer can provide added assurance, especially for larger or more complex systems.
Conclusion
For families seeking a reliable all-around solution, the Thule Motion 3 offers a balanced mix of capacity, ease of use, and security, making it the best overall choice. If space is your top priority and you want maximum storage, the Yakima SkyBox NX 18 XLG stands out as the best premium option. Budget-conscious families can find great value in models like the GarveeTech Rooftop Cargo Box, which combines affordability with durability. Beginners or infrequent travelers might prefer simpler, more straightforward models, while larger families or those with extensive gear needs should consider bigger capacities and features like dual-side access. Select based on your specific trip requirements, vehicle compatibility, and budget to make the most of your family adventures.
