The Ultimate Buying Guide for Your Car Topper
A car topper, often called a roof box or cargo carrier, lets you carry extra gear on your car’s roof. It’s perfect for road trips, camping, or carrying sports equipment. Choosing the right one makes a big difference. This guide helps you find the best fit for your needs.
1. Key Features to Look For
When shopping for a car topper, focus on these important features:
Capacity and Size
- Volume (Cubic Feet): This tells you how much stuff fits inside. Small toppers hold about 10 cubic feet. Large ones can hold 20 cubic feet or more. Think about your biggest trips.
- Length and Width: Measure your car’s roof space first. Make sure the topper fits without hanging over too much or blocking your view.
Security and Access
- Locking System: Good toppers have strong locks. This keeps your gear safe from thieves. Always choose one with secure, easy-to-use locks.
- Opening Mechanism: Some open from one side. Premium models often open from both sides (dual-side opening). Dual-side opening makes loading and unloading much easier.
Aerodynamics
- Look for a sleek, curved shape. A good aerodynamic design reduces wind noise and saves a little on gas mileage, especially on long highway drives.
2. Important Materials Matter
The material used determines how tough and light the topper is.
ABS Plastic (Acrylonitrile Butadiene Styrene)
- This is very common. It is strong, light, and resists scratches well. Most high-quality toppers use UV-stabilized ABS plastic.
Fiberglass
- Fiberglass is extremely durable and often used for the highest-end, largest boxes. It handles rough weather very well.
Mounting Hardware
- Check the clamps and brackets. Strong metal hardware (usually steel or heavy-duty aluminum) ensures the topper stays firmly attached to your roof racks.
3. Factors That Improve or Reduce Quality
Quality affects how long your topper lasts and how well it performs.
Factors That Improve Quality
- Weatherproofing: Excellent seals around the lid prevent rain and snow from getting inside.
- Stiffening Ribs: Boxes with internal support structures do not flex much when driving fast. This keeps them stable.
- Warranty: A long warranty (often 5 years or more) shows the manufacturer trusts its product.
Factors That Reduce Quality
- Thin Plastic: Very thin plastic can crack easily in cold weather or warp under strong sunlight.
- Poor Latches: Cheap latches might fail or rattle loudly while you drive.
- Complex Installation: If the mounting system is hard to figure out, you might install it incorrectly, which is dangerous.
4. User Experience and Use Cases
Think about how you plan to use your topper.
Road Trips and Family Travel
If you pack suitcases for a family vacation, you need a large, dual-opening box. Easy access is very important when you stop frequently.
Sports and Hobbies
- Skiing/Snowboarding: Look for long, narrow boxes designed specifically for skis. These often have special internal straps.
- Camping Gear: Tents, sleeping bags, and bulky chairs fit well in wider, shorter boxes.
Installation
Most modern toppers mount easily onto existing crossbars. Some require you to buy crossbars separately. Check how quickly you can attach and remove the box. If you only use it a few times a year, quick-release mounting hardware is a huge plus.
Frequently Asked Questions (FAQ) About Car Toppers
Q: Will a car topper hurt my gas mileage?
A: Yes, any box on your roof adds wind resistance. A well-designed, aerodynamic topper causes a small drop, usually 5% to 15%. Driving slower helps reduce this effect.
Q: Do I need special roof racks to install a topper?
A: Most toppers require existing crossbars (side rails that go across the roof). Some brands sell toppers that include the mounting system, but always check if you need separate crossbars.
Q: How much weight can a car topper safely hold?
A: The weight limit depends on two things: the box itself and your car’s roof weight limit. Check your car manual for the roof limit. Most toppers hold between 100 and 165 pounds.
Q: Can I wash the car topper while it is installed?
A: Yes, you can usually wash the box with soap and water when it is attached. However, it is much easier to clean thoroughly if you take it off the car first.
Q: Are car toppers waterproof?
A: Good quality toppers are highly water-resistant and should keep gear dry in normal rain. They are not always 100% submersible proof, so extremely heavy, prolonged downpours might let a tiny bit of moisture in through the seals.
Q: How do I stop the box from rattling on the highway?
A: Rattling usually means the mounting clamps are too loose or the lid latches are not fully engaged. Make sure all hardware is tightened securely before you drive.
Q: What is the difference between ABS and Fiberglass toppers?
A: ABS plastic is lighter and cheaper. Fiberglass is usually stronger, handles rougher conditions better, and often has a slightly smoother finish.
Q: Can a car topper be opened from both sides?
A: Many mid-range and premium models offer dual-side opening. This is a major convenience feature, allowing you to reach gear from either side of the car.
Q: Are car toppers hard to install by myself?
A: For smaller boxes, one person can often manage the installation. Larger, heavier boxes are much safer and easier to install with two people, especially when lifting them onto the roof.
Q: Should I get a clear or dark-colored topper?
A: Dark colors hide road grime better. If the topper sits in direct sun often, a lighter color might absorb slightly less heat inside, keeping sensitive items a bit cooler.
