The Ultimate Buying Guide: Choosing the Perfect Cargo Box
A cargo box is a fantastic way to add storage space to your vehicle. Whether you are heading on a long road trip or just need extra room for gear, these boxes mount securely to your roof rack. This guide will help you pick the best one for your needs.
Key Features to Look For
When shopping, several important features make a big difference in how well the box works for you.
Size and Capacity
- Volume (Cubic Feet): Think about how much stuff you need to carry. Small boxes hold skis or small bags. Large boxes fit camping gear or multiple suitcases.
- Length and Width: Measure your roof space. Make sure the box fits without hanging over your windshield or rear hatch too much.
Opening Mechanism
- Dual-Side Opening: This is a huge convenience. It lets you access your gear from either side of the car. This is very helpful when parked close to a wall.
- Hinge Quality: Look for strong hinges that hold the lid open while you load or unload.
Security and Locking
Your gear needs to stay safe. Good cargo boxes come with a strong locking system. Make sure the lock is easy to use but very hard for thieves to break.
Important Materials Matter
The material used determines how long the box lasts and how well it protects your things from the weather.
ABS Plastic
Most good cargo boxes use ABS (Acrylonitrile Butadiene Styrene) plastic. This material is strong and lightweight. It resists impacts well. It is the most common choice for good reasons.
Polycarbonate
Some premium boxes use polycarbonate. This material is even tougher than ABS. It handles extreme cold better without cracking. These boxes often cost more.
UV Resistance
The plastic must resist the sun’s rays. If the plastic is not UV resistant, the box can become brittle and fade over time. This reduces its lifespan.
Factors That Improve or Reduce Quality
Quality isn’t just about the main material. The design details really matter.
Aerodynamics
A sleek, low-profile design reduces wind noise. Boxes that are very square create a loud whistling sound when you drive fast. Better aerodynamics also help save a little bit on gas mileage.
Ease of Installation
A quality box installs quickly and securely onto your existing roof racks. Look for tool-free mounting systems. Complicated installations frustrate users quickly.
Weatherproofing
Check the seams and seals around the lid. Water must not leak in during heavy rain. A poorly sealed box ruins your luggage.
User Experience and Use Cases
How you plan to use the box should guide your purchase.
- Road Trips: If you travel long distances, prioritize low noise and easy access (dual-side opening).
- Winter Sports: For skis and snowboards, you need a long, narrow box. Make sure it fits your longest equipment.
- Daily Use/Commuting: If you only need a little extra room, a smaller, aerodynamic box is perfect.
Remember to check your vehicle’s roof weight limit. Do not overload the box or the roof rack system.
Frequently Asked Questions (FAQ) About Cargo Boxes
Q: Will a cargo box hurt my gas mileage?
A: Yes, a cargo box will slightly lower your gas mileage. This happens because the box creates more wind resistance (drag). A well-designed, aerodynamic box causes less of a drop than a box with a boxy shape.
Q: How hard is it to install a roof cargo box?
A: Most modern cargo boxes are designed for easy installation. Many systems use clamps that attach directly to your crossbars. If the box has a tool-free mounting system, you can often install it in under 30 minutes.
Q: Can I still open my rear hatch with the box installed?
A: This depends on the size of your vehicle and the box. If you have a small SUV or hatchback, mounting the box further back might block the hatch door from fully opening. Always check the box’s placement relative to your hatch before buying.
Q: Are all cargo boxes waterproof?
A: Most quality boxes are highly water-resistant, meaning they handle rain and snow well. However, very few are 100% submersible waterproof. Strong seals are the key to keeping gear dry in a storm.
Q: What is the difference between a cargo box and a cargo basket?
A: A cargo box is fully enclosed and locks to protect items from weather. A cargo basket is an open frame. Baskets are great for dirty or oddly shaped items but require you to use a separate waterproof bag to protect your gear.
Q: How do I clean my plastic cargo box?
A: Cleaning is simple. Use mild soap and water with a soft cloth or sponge. Avoid harsh chemical cleaners, as these can damage the plastic finish and UV protection.
Q: Do I need a roof rack before buying a cargo box?
A: Yes, almost always. Cargo boxes attach to crossbars, which are part of a roof rack system. You must confirm that the box mounting hardware matches the type of crossbars you currently have.
Q: Can I leave the cargo box on all year long?
A: Yes, you can leave it on. Many people leave them on year-round for extra storage. Just remember that driving without a load might slightly increase wind noise.
Q: What is the weight limit for a cargo box?
A: The weight limit is set by the weakest link: either the box itself or your vehicle’s roof capacity. Check both manuals. Most boxes hold between 100 and 150 pounds, but your car’s limit might be lower.
Q: Are expensive cargo boxes worth the extra money?
A: Often, yes. More expensive boxes usually have better materials (like polycarbonate), superior UV protection, quieter aerodynamics, and more reliable locking mechanisms. They last longer and perform better in bad weather.
