Your Guide to Choosing the Best Rooftop Cargo Box
A rooftop cargo box is a fantastic way to increase your vehicle’s storage. It frees up space inside your car for a more comfortable trip. Whether you are heading on a long road trip or moving gear for a hobby, these boxes are lifesavers. Picking the right one means looking closely at a few important things. This guide helps you choose the perfect box for your needs.
Key Features to Look For
When shopping, certain features make a big difference in how well the box works for you.
Size and Capacity
- Volume (Cubic Feet): This tells you how much stuff fits inside. Think about your typical trips. A small family might need 10-14 cubic feet. Larger groups or skiers need 18 cubic feet or more.
- Length: Make sure the box fits your roof rack without blocking your rear hatch or trunk door.
Ease of Use
- Mounting System: Look for easy-to-use clamps or mounting hardware. Some systems attach quickly with one hand. This saves a lot of frustration.
- Opening Mechanism: Dual-side opening is a huge benefit. It lets you access gear from either side of the car.
Security and Durability
- Locking System: Always choose a box with strong, built-in locks. You want your gear safe while you stop for gas or stay overnight.
- Weatherproofing: Good seals keep rain and dust out. Your luggage stays dry, no matter the weather.
Important Materials
The material a box uses affects its weight, strength, and price.
- ABS Plastic (Acrylonitrile Butadiene Styrene): This is very common. It is strong, lightweight, and resists impacts well. Many good boxes use this material.
- Fiberglass: Fiberglass boxes are often the toughest and most aerodynamic. They usually cost more but last a very long time.
Factors That Improve or Reduce Quality
Quality is not just about the material. How the box is built matters a lot.
What Makes a Box Better?
- Aerodynamics: Sleek, curved designs reduce wind noise and drag. This helps your gas mileage slightly.
- UV Resistance: Good materials resist fading and becoming brittle from the sun. High-quality boxes keep their color and shape longer.
- Stiff Bottom Plate: A strong base prevents the box from flexing too much when loaded with heavy items.
What Lowers Quality?
- Thin, Flimsy Plastic: Cheap boxes might crack easily if you hit them with a shovel or heavy bag.
- Poor Latches: Weak latches can sometimes pop open slightly at high speeds if not secured tightly.
User Experience and Use Cases
Think about how you plan to use the box most often. This helps you decide between size and style.
Road Trips and Family Travel
Families need space for suitcases, strollers, and snacks. A large, dual-opening box makes packing and unpacking much simpler when traveling long distances.
Sports and Hobby Gear
Do you carry skis, snowboards, or camping equipment? Look for boxes specifically designed for long, thin items. Some boxes have internal tie-downs to keep gear from sliding around.
Daily Commuting (Less Common)
If you only need a little extra space for groceries or sports bags on occasion, a smaller, lower-profile box works well. These are easier to take on and off your vehicle.
10 Frequently Asked Questions (FAQ)
Q: Will a rooftop box hurt my car’s gas mileage?
A: Yes, any box adds wind resistance. A well-designed, aerodynamic box causes less of a drop than a boxy, cheap one. Expect a small drop, usually 5% to 15%.
Q: Can I wash my rooftop cargo box?
A: Absolutely. You should clean the outside regularly with mild soap and water, just like washing your car.
Q: How much weight can a cargo box safely hold?
A: This depends on the box model and your car’s roof weight limit. Check both manuals, but most boxes safely hold between 100 and 165 pounds.
Q: Do I need roof racks to install a cargo box?
A: Yes, almost all boxes require crossbars (part of a roof rack system) to attach them securely to your car’s roof.
Q: Are rooftop boxes hard to install?
A: Modern boxes are much easier than older models. Many can be installed by one person in under 30 minutes if the crossbars are already in place.
Q: What is the difference between ABS and Fiberglass boxes?
A: ABS is lighter and cheaper. Fiberglass is usually stronger, more durable against scratches, and often offers better aerodynamics.
Q: Can I open my trunk or hatch with the box installed?
A: You must check the box length against your car. A longer box might hit your rear door when fully opened. Measure carefully before buying.
Q: Are these boxes waterproof?
A: Good quality boxes are highly water-resistant. They use tight seals. However, driving through a severe storm might let a tiny bit of moisture seep in near the hinges.
Q: What is “load distribution”?
A: This means spreading the weight evenly across the roof bars. Do not put all the heavy items on one side of the box; balance them out.
Q: How long do cargo boxes typically last?
A: With proper care, a quality ABS or Fiberglass box can last 10 years or more. The hardware might need tightening over time.
