The Ultimate Buying Guide: Choosing the Best Cargo Box for Your Subaru Outback
The Subaru Outback is built for adventure. However, even the largest SUV runs out of trunk space quickly. A roof-mounted cargo box solves this problem. It keeps your gear dry and secure while you travel. Use this guide to find the perfect fit for your vehicle.
1. Key Features to Look For
When shopping for a cargo box, look for a dual-side opening feature. This allows you to access your gear from either the driver’s side or the passenger’s side. Also, consider the locking system. A secure, multi-point lock protects your items from theft. Finally, check the mounting hardware. Quick-mount systems let you attach the box to your roof rails in minutes without tools.
2. Important Materials
Most high-quality boxes use ABS plastic. This material is strong, lightweight, and resistant to UV rays. It prevents the box from cracking under the hot sun. Some premium models use reinforced fiberglass or multi-layer plastics. These materials offer extra rigidity and strength for heavy loads. Always choose a material that can handle extreme weather conditions.
3. Factors That Affect Quality
Aerodynamics play a huge role in quality. A sleek, low-profile design reduces wind noise and drag. This saves you money on fuel. Another factor is the hinge system. High-quality boxes use heavy-duty struts to hold the lid open. This prevents the lid from slamming shut while you load your bags. Lastly, check the weather seals. A good seal keeps out rain, snow, and road dust.
4. User Experience and Use Cases
Think about what you plan to haul. If you are a skier, you need a long, narrow box to fit your skis. If you are a camper, a wider and taller box is better for tents and coolers. Most users find that a medium-sized box fits the Subaru Outback roof perfectly. It leaves room for other accessories like bike racks. Always remember that a full box changes how your car handles corners. Drive slowly and be careful with low-clearance parking garages.
Frequently Asked Questions
Q: Will a cargo box fit all Subaru Outback models?
A: Most modern Outbacks come with integrated roof rails. You will need crossbars to mount the box. Always check your specific model year to ensure the crossbars are compatible.
Q: Does a cargo box hurt my gas mileage?
A: Yes, it will slightly lower your fuel efficiency due to wind resistance. Choosing an aerodynamic, low-profile box helps minimize this impact.
Q: Can I install the box by myself?
A: You can, but it is much easier with two people. The boxes are large and awkward to lift onto the roof alone.
Q: How much weight can I put in the box?
A: Check your Subaru’s roof weight limit. Most Outback roofs hold about 150 pounds. Remember to subtract the weight of the box itself from that total.
Q: Are these boxes waterproof?
A: Most are weather-resistant. They keep rain and snow out, but they are rarely 100% submersible. Use dry bags for items that must stay perfectly dry.
Q: Should I remove the box when I am not using it?
A: You should remove it if you want the best gas mileage. However, if you travel often, leaving it on is fine.
Q: Do I need a specific brand for my Subaru?
A: No. Major brands like Thule, Yakima, and Rhino-Rack all make models that fit the Subaru Outback perfectly.
Q: How do I clean my cargo box?
A: Use mild soap and water. Avoid harsh chemicals or abrasive scrubbers, as these can damage the plastic finish.
Q: Will the box block my sunroof?
A: Most boxes will not block the sunroof. However, you should check the clearance between the box and the glass to avoid rattling.
Q: Is the box secure from thieves?
A: Yes. Most boxes come with high-quality locks. Never leave valuables like electronics or passports in the box overnight.
