Your Essential Guide to Choosing the Perfect Cargo Box
A cargo box is a fantastic addition to any vehicle. It gives you extra space for road trips, camping gear, or just big shopping runs. Picking the right one can seem tricky. This guide helps you find the best fit for your needs.
Key Features to Look For
Good cargo boxes offer smart features that make life easier. Pay close attention to these:
Capacity and Size
- Volume (Cubic Feet): This tells you how much stuff fits inside. A small family might need 10-15 cubic feet. A big family going on a long vacation likely needs 18 cubic feet or more.
- External Dimensions: Measure your vehicle’s roof space. Make sure the box fits without hanging over the windshield or blocking the rear hatch.
Mounting System
- Ease of Installation: Look for tool-free mounting systems. These systems clamp onto your existing roof racks quickly.
- Compatibility: Check if the box works with your car’s crossbars (the bars running side-to-side across the roof).
Security and Access
- Locking Mechanism: Always choose a box with strong, built-in locks. You want your gear safe from thieves.
- Opening Style: Most boxes open from one side (driver or passenger). Dual-side opening boxes are much more convenient. They let you reach gear from either side of the car.
Important Materials and Durability
The material used determines how long your box lasts and how much it protects your items.
Plastic vs. Fiberglass
- ABS Plastic (Acrylonitrile Butadiene Styrene): This is the most common material. It is light and strong. Good ABS plastic resists cracking in the cold.
- High-Density Polyethylene (HDPE): Similar to ABS, HDPE handles impacts well.
- Fiberglass: Fiberglass boxes cost more. They offer superior strength and a smoother, more aerodynamic look. They often last the longest.
Weather Resistance
Ensure the box has strong seals around the lid. These seals keep rain, snow, and dust out. A high-quality hinge design also plays a big role in keeping water away from your belongings.
Factors That Affect Quality
Not all cargo boxes are created equal. A few details separate the great ones from the mediocre ones.
Improving Quality
- Sturdy Hinges and Gas Struts: Gas struts (like those on a car trunk) help hold the lid open while you load. Strong metal hinges resist bending.
- UV Protection: Sunlight breaks down plastic over time, making it brittle. Boxes with UV inhibitors last longer without fading or cracking.
Reducing Quality (Things to Avoid)
- Flimsy Latches: If the latches feel weak when you press them, they might fail on the highway.
- Excessive Flex: When you press on the lid, it should feel solid. If the plastic bends easily, it might warp under wind pressure at high speeds.
User Experience and Use Cases
Think about how you plan to use the box. This guides your purchase decision.
Road Trips and Camping
If you pack bulky items like tents, sleeping bags, and coolers, you need a long, wide box. Aerodynamics matter here. A sleek, low-profile box cuts down on wind noise and saves a little gas.
Everyday Use and Sports Gear
For skis, snowboards, or fishing rods, look for boxes specifically designed for long, narrow items. Some boxes have internal tie-downs to stop gear from sliding around.
Loading and Unloading
Consider your height. If you are shorter, a lower-profile box or one with dual-side opening makes loading much easier. Getting heavy items up high can be tough.
Top 10 Cargo Box Buying FAQs
Q: How much weight can a cargo box safely hold?
A: Most standard cargo boxes hold between 100 and 150 pounds. Always check the box instructions AND your vehicle’s roof rack weight limit. The lower limit is the one you must follow.
Q: Will a cargo box hurt my gas mileage?
A: Yes, any added weight and wind resistance will lower your mileage slightly. Aerodynamic designs cause less drag, so they hurt your mileage less than boxy, square designs.
Q: Do I need roof racks to use a cargo box?
A: Yes, almost always. Cargo boxes attach to crossbars. If your car doesn’t have them, you must buy a complete roof rack system first.
Q: What is the main difference between a roof bag and a roof box?
A: A roof bag is soft and made of fabric, like a large duffel bag. A roof box is hard-sided plastic or fiberglass. Hard boxes offer much better protection from weather and theft.
Q: How do I stop my stuff from sliding around inside?
A: Use non-slip mats or rubberized shelf liners inside the box. Also, pack heavy items on the bottom and secure loose gear using built-in straps or cargo nets.
Q: How loud are cargo boxes on the highway?
A: Quality boxes are designed to be quiet. Cheaper or poorly installed boxes often create a whistling sound due to wind rushing over seams or mounting hardware.
Q: Are cargo boxes waterproof?
A: They are highly water-resistant. Good seals keep out rain and snow during normal driving. However, submerging them (like in a car wash sprayer) might let a small amount of water in.
Q: What is the best way to clean a plastic cargo box?
A: Use mild soap and water. A soft cloth or sponge works well. Avoid harsh chemical cleaners, as they can damage the plastic finish or UV coating.
Q: How important is aerodynamics?
A: Aerodynamics are very important for long drives. A sleek, low-profile box reduces wind noise and drag, making your drive more comfortable and slightly more fuel-efficient.
Q: Can I fit skis or snowboards in any box?
A: No. Check the internal length measurement. You need a box that is longer than your longest ski or snowboard. Many boxes are labeled as “snow sport compatible.”
