Your Roof Top Cargo Box Buying Adventure: Gear Up for Space!
Do you love road trips but hate stuffing your car to the ceiling? A roof top cargo box is your new best friend. It straps onto your car’s roof, giving you tons of extra storage space. This guide helps you pick the perfect one.
Key Features to Look For
When shopping, look closely at what the box offers. These features make your life easier and your gear safer.
Size and Capacity
- Volume (Cubic Feet): This tells you how much stuff fits inside. A small family might need 10-14 cubic feet. Big families or long trips might need 18+ cubic feet.
- Length and Width: Make sure the box fits your car’s roof rack without hanging over too much. Check your car’s manual for limits.
Opening Style and Access
- Dual-Side Opening: This is a huge bonus! It lets you open the box from either side of the car. You don’t have to walk all the way around on the side closest to traffic.
- Hinges and Latches: Good boxes have strong hinges that hold the lid open while you load. The latches should click firmly so you know your gear is locked tight.
Security and Durability
- Locking System: Always choose a box with built-in, key-operated locks. These keep thieves away from your valuables.
- Weatherproofing: The box must keep rain and snow out. Look for strong seals around the edges.
Important Materials Matter
The material decides how long the box lasts and how much it weighs.
ABS Plastic (Acrylonitrile Butadiene Styrene)
Most good boxes use ABS plastic. This material is strong. It resists impacts, like small rocks hitting it. It also handles sun and weather well. This material improves quality significantly.
Fiberglass
Fiberglass boxes are often lighter and sometimes look sleeker. However, they can cost more. They offer excellent strength for their weight.
Mounting Hardware
The clamps and bolts that attach the box to your roof rack should be made of sturdy metal, usually steel or aluminum. Cheap plastic hardware reduces quality quickly.
Factors That Improve or Reduce Quality
Quality isn’t just about the material; it’s about the design.
Aerodynamics (Better Quality)
Sleek, curved boxes cut through the wind better. This helps keep your gas mileage from dropping too much. Boxes that stick up too high create more drag and noise.
Internal Features (Better Quality)
Some boxes include tie-down straps inside. Some even have interior lights. These small things make loading and unloading much nicer.
Installation Complexity (Reduced Quality)
A box that is very hard to install usually means poor design. Look for systems that clamp onto your existing crossbars quickly, often using a simple turn of a knob.
User Experience and Use Cases
Think about how you will actually use the box.
Weekend Warrior
If you only use it for camping gear or ski trips, a medium-sized, easy-to-install box is perfect. Dual-side opening is very useful here.
Family Road Trips
For long summer vacations, you need maximum space. Choose the largest box that safely fits your vehicle. You will be loading and unloading often, so easy latches are crucial.
City Parking
If you park in tight garages, measure your car’s total height *with* the box installed! A tall box might not fit under low garage doors. Shorter, wider boxes are sometimes better for city living.
Frequently Asked Questions (FAQ)
Q: Will a roof box slow down my car a lot?
A: Yes, any box will slow you down a little. A smooth, aerodynamic box slows you down less than a boxy, square one. You will use more gas, especially at highway speeds.
Q: Do I need special bars on my roof first?
A: Yes, most cargo boxes attach to existing crossbars. These bars run side-to-side across your roof. If you don’t have them, you must buy a roof rack system first.
Q: Can I wash the cargo box?
A: Absolutely. You clean the box like you clean your car. Use mild soap and water. Avoid high-pressure washing directly on the seals.
Q: How much weight can the box hold?
A: The box has its own weight limit (check the manual). Your car’s roof also has a weight limit. You must follow the *lower* of those two limits.
Q: Are they hard to install by myself?
A: Some are easy; some are tricky. Boxes with tool-free mounting systems are much easier for one person to handle. Ask a friend for help when lifting the box onto the roof.
Q: Can I still open my trunk if I have a box?
A: Usually, yes. But if you buy a very long box for a small SUV or hatchback, the box might block the trunk door from opening all the way up. Always measure the overhang!
Q: What happens if I get a flat tire while the box is on?
A: Nothing bad happens to the box. You can still safely change a tire, but the box might make it harder to reach your spare tire, depending on where your spare is stored.
Q: Are expensive boxes always better?
A: Not always. Mid-range boxes often offer 90% of the features of the most expensive ones. Focus on strong locks and good weather sealing, not just brand name.
Q: Do I have to take the box off in the winter?
A: No. Many people leave them on year-round. If you do remove it, make sure you store it somewhere dry and secure, like a garage.
Q: What is ‘UV resistance’?
A: This means the plastic resists damage from the sun’s rays. Good UV resistance stops the box from becoming brittle and cracking over many years of bright sunshine.
