Your Essential Roof Cargo Box Buying Guide
A roof cargo box is a fantastic helper for road trips. It gives you extra space for luggage, camping gear, or sports equipment. Choosing the right one takes a little thought. This guide helps you pick the best box for your needs.
Key Features to Look For
When shopping, certain features make a big difference in how useful your box is.
Capacity and Size
- Volume: Boxes come in different sizes, usually measured in liters. A family going on a week-long vacation needs a bigger box (400 liters or more). A couple on a weekend trip might only need a smaller one (250-350 liters).
- Length vs. Width: Measure your vehicle’s roof space. Make sure the box fits without blocking your trunk opening or touching the antenna.
Security and Access
- Locking System: Always choose a box with strong, built-in locks. You want your gear safe from thieves.
- Opening Mechanism: Dual-sided opening is a huge plus. This lets you open the box from either the driver’s or passenger’s side. It makes loading and unloading much easier, especially in tight parking spots.
Aerodynamics and Noise
Look for boxes with a sleek, low-profile design. A good shape cuts down on wind noise (whistling) while you drive fast. This makes your trip much quieter.
Important Materials Used in Construction
The material affects how long the box lasts and how much it weighs.
ABS Plastic
Most good boxes use ABS plastic. This material is strong and lightweight. It resists dents well. High-quality ABS plastic handles sun exposure without cracking easily.
Fiberglass
Fiberglass boxes are often the strongest and most aerodynamic. However, they usually cost more money. They offer excellent protection against weather.
UV Resistance
Ensure the material has UV inhibitors. Sunlight fades and weakens plastic over time. A UV-resistant shell stays strong for years.
Factors That Improve or Reduce Quality
Quality isn’t just about the material; it’s also about the engineering.
Mounting System
A fast, easy mounting system is crucial. Look for tool-free mounting clamps. These systems grip your crossbars securely. A poor mounting system can vibrate loose on long drives, which is dangerous.
Weight Capacity
Every box has a maximum weight limit. Do not overload it. Check your vehicle’s roof weight rating too; sometimes the car roof limits the weight before the box does.
Weatherproofing
Excellent quality boxes have strong seals around the edges. These seals keep rain and dust out. Poorly sealed boxes let moisture in, ruining your stored items.
User Experience and Use Cases
Think about how you plan to use the box most often.
Road Trips and Vacations
If you pack bulky items like strollers or large suitcases, you need a box with high volume and wide opening access. Dual-sided opening becomes very important here.
Winter Sports
If you carry skis or snowboards, check the box’s internal length. Make sure your longest ski or board fits completely inside. Some boxes are specifically designed for long, narrow gear.
Daily Driving
If you plan to keep the box on your car all the time, prioritize aerodynamics and low weight. A heavy, bulky box hurts your gas mileage significantly.
Frequently Asked Questions (FAQ) About Roof Cargo Boxes
Q: Will a roof box hurt my gas mileage?
A: Yes, any added item on the roof increases wind resistance. A well-designed, aerodynamic box hurts mileage less than a cheap, boxy one. Expect a small drop in MPG.
Q: Can I wash my roof cargo box?
A: Absolutely. Most boxes can be washed with mild soap and water, just like your car. Avoid high-pressure washing directly on the seams.
Q: How difficult is it to install a roof box?
A: Installation difficulty varies. Boxes with quick-clamp systems can often be installed in under 30 minutes by one person. Always read the instructions carefully.
Q: Do I need roof crossbars?
A: Yes. Roof cargo boxes attach to crossbars, which run across the width of your roof. If your car does not have factory roof rails, you must buy crossbars separately.
Q: What is the difference between a cargo box and a cargo basket?
A: A cargo box is fully enclosed and locks, protecting items from weather and theft. A cargo basket is an open tray that requires you to use waterproof bags to protect your gear.
Q: Can I open my trunk if the box is installed?
A: This depends on the box size and your car. Longer boxes mounted too far forward might block the trunk lid from opening fully. Measure carefully before buying.
Q: Are roof boxes waterproof?
A: Good quality boxes are highly weather-resistant and keep most rain out. No box is 100% guaranteed against extreme flooding or pressure washing, but they handle normal driving rain very well.
Q: How much weight can my roof safely carry?
A: Check your vehicle owner’s manual for the dynamic (moving) roof weight limit. This limit is usually lower than the static (parked) limit.
Q: What is UV resistance in a box?
A: UV resistance means the plastic has special additives that stop the sun’s rays from making the plastic brittle or faded over time.
Q: Should I buy a hard or soft cargo carrier?
A: Hard carriers (boxes) offer superior security and weather protection. Soft carriers (bags) are cheaper and store easily when empty, but they offer less protection.
