1. Thule Motion XT L: Best Overall
We researched the Thule Motion XT L extensively. Based on owner feedback and the spec sheet, it offers excellent aerodynamics and low wind noise, thanks to the AeroSkin texture and sleek shape. The dual-side opening and Power-Click mounting system make loading and installation straightforward. In our evaluation, its build quality and safety features (locking mechanism, reinforced lid) are top-notch.
However, the Motion XT L is among the pricier options. If budget is a primary concern, you might want to consider the Yakima GrandTour 16. Also, its 110 lb load limit may be insufficient for extremely heavy gear. This box is best for SUV owners who prioritize aerodynamics, ease of use, and are willing to invest in a premium product.
- Dual-side opening with Power-Click quick-mount system
- AeroSkin texture reduces wind noise and drag
- Integrated lid stays open for easy loading
Pros: Very aerodynamic and quiet on highway; Easy to install and remove with one person
Cons: Premium price point
2. Yakima GrandTour 16: Runner Up
We compared the Yakima GrandTour 16 against other models. According to owner feedback and manufacturer specs, it offers a high load limit of 165 lbs, making it suitable for heavier items. The dual-side opening and HD SuperLock system provide convenience and security. In our evaluation, the UV-resistant shell and robust hinges suggest good long-term durability.
However, the GrandTour 16 is heavier (47 lbs) than the Thule Motion XT L, which may make installation more challenging for some. Additionally, the interior shape is not as optimized for tall items. This box is best for SUV owners who need to carry heavy gear and value security features, but it may not be ideal for those seeking the lightest option.
- Dual-side opening with HD SuperLock
- Aero-sculpted shape reduces drag
- Includes SKS locks for added security
Pros: High load capacity for its size; Durable construction with UV-resistant materials
Cons: Heavier than some competitors
3. SportRack Horizon 16: Best Value
We evaluated the SportRack Horizon 16 as a budget-friendly option. Based on owner reviews and specs, it provides a good balance of capacity and weight. The dual-side opening and quick-release mounts make it convenient. In our evaluation, its lightweight construction (34 lbs) is a plus for easy installation.
However, the 100 lb load limit is lower than many competitors, and some owners report the latch mechanism is not as smooth as premium brands. The durability may be adequate for occasional use but may not withstand heavy-duty trips. This box is best for budget-conscious SUV owners who need a reliable roof box for light to moderate use, but those requiring higher capacity or premium feel should look elsewhere.
- Dual-side opening with quick-release mounting system
- Lightweight design at 34 lbs
- Aerodynamic shape with textured finish
Pros: Affordable without major compromises; Lightweight and easy to handle
Cons: Lower load limit of 100 lbs; Latch mechanism feels less premium
4. Thule Force XT L: Top Pick for Durability
We researched the Thule Force XT L, focusing on durability. Based on the spec sheet and owner feedback, its reinforced ABS shell and heavy-duty hinges are built to last. The SlideLock system provides excellent security. In our evaluation, this box is one of the most robust on the market.
However, the single-side opening can be inconvenient when parked on the passenger side. Also, its price is similar to the Motion XT L but with fewer features. This box is best for SUV owners who prioritize longevity and security over convenience, but those who want dual-side opening should consider the Motion XT L.
- Single-side opening with SlideLock system
- Reinforced lid and robust hinges
- Textured ABS shell for scratch resistance
Pros: Extremely durable construction; Secure locking mechanism
Cons: Single-side opening limits convenience; Higher price point
5. Yakima SkyBox LoPro 15: Best Low-Profile
We evaluated the Yakima SkyBox LoPro 15 for its low-profile design. According to owner feedback, it fits easily under garage doors and has good aerodynamics. The dual-side opening is convenient. In our evaluation, its build quality is solid, though not as heavy-duty as the Force XT.
However, the 15 cu ft capacity and 100 lb load limit are lower than standard boxes, limiting what you can carry. This box is best for SUV owners with low garage clearance who need a compact cargo solution, but those needing more space should look at larger models.
- Low-profile design fits in garages
- Dual-side opening with HD SuperLock
- Sleek shape reduces wind resistance
Pros: Fits in low-clearance garages; Easy to load from both sides
Cons: Smaller capacity (15 cu ft); Lower load limit (100 lbs)
6. SportRack Vista XL 18: Best Large Capacity
We researched the SportRack Vista XL 18 as a large-capacity option. Based on owner reviews, it offers ample space for camping gear or luggage. The dual-side opening is a plus. In our evaluation, its lightweight design (38 lbs) is impressive for an 18 cu ft box.
However, the 100 lb load limit is low for its size, meaning you can fill it with bulky but light items only. Some owners have reported latch durability concerns. This box is best for SUV owners who need maximum volume for lightweight items, but those carrying heavy gear should choose a box with higher load capacity.
- Extra-large 18 cu ft capacity
- Dual-side opening with quick-mount system
- Aerodynamic shape for reduced drag
Pros: Spacious interior for bulky items; Lightweight for its size
Cons: Load limit only 100 lbs despite large size; Some owners report latch issues over time
7. INNO Shadow 16: Sleek Design
We evaluated the INNO Shadow 16, focusing on its design. Based on owner feedback, it has a sleek, glossy appearance that many find appealing. The dual-side opening and central locking are convenient. In our evaluation, it offers decent performance for the price.
However, some owners report that the build quality is not on par with premium brands like Thule or Yakima. The locks can be stiff, and the shell may show scratches more easily. This box is best for SUV owners who prioritize aesthetics and occasional use, but those seeking long-term durability may be disappointed.
- Sleek, low-profile design with gloss finish
- Dual-side opening with central locking
- Mounting system compatible with most crossbars
Pros: Attractive appearance; Dual-side opening
Cons: Build quality not as robust as Thule/Yakima; Locks can be stiff to operate
Frequently Asked Questions
How do I choose the right size roof box for my SUV?
Consider your vehicle’s roof load capacity and the type of gear you carry. Measure the available roof space and check your crossbar spread. A 16 cu ft box is suitable for most families, while larger boxes (18 cu ft) are better for bulky items. Ensure the box’s weight plus cargo does not exceed your roof’s dynamic load limit.
Can I install a roof box by myself?
Most modern roof boxes are designed for one-person installation using quick-mount systems. However, heavier boxes (over 40 lbs) may be easier with two people. Always follow the manufacturer’s instructions and ensure the box is securely attached before driving.
Will a roof box affect my SUV's fuel economy?
Yes, any roof box increases wind resistance and reduces fuel economy. Aerodynamic models like the Thule Motion XT L minimize drag. Expect a decrease of 10-25% on highways, depending on speed and box shape. Remove the box when not in use to improve efficiency.
Are roof boxes safe for my SUV's roof?
Yes, when installed correctly and within load limits. Use a box with a secure locking system and ensure your roof crossbars are rated for the weight. Regularly check the mounting hardware during long trips. Avoid exceeding the vehicle’s roof load capacity specified in the owner’s manual.
How do I maintain and clean my roof box?
Wash with mild soap and water, avoiding abrasive cleaners. Lubricate locks and hinges periodically with silicone spray. Store the box in a dry, shaded area to prevent UV damage. Inspect seals and latches before each season.
Our Verdict
After comparing specifications and owner feedback, the Thule Motion XT L is our top pick for its excellent aerodynamics, dual-side opening, and ease of use. For a slightly lower price with high load capacity, the Yakima GrandTour 16 is a strong runner-up. Choose based on your priorities for weight, capacity, and budget.
