The Ultimate Buying Guide for Car Top Carriers
A car top carrier is a fantastic way to get extra storage space for your vehicle. If you love camping, road trips, or hauling sports gear, this accessory is a game-changer. Choosing the right one involves looking closely at a few important things. We break down what you need to know before you buy.
Key Features to Look For
Capacity and Size
Car top carriers come in different sizes. Think about what you need to carry. Do you need space for a weekend trip, or a two-week family vacation? Carriers are measured in cubic feet (cu. ft.). Larger carriers (18-22 cu. ft.) hold a lot of luggage. Smaller carriers (10-15 cu. ft.) are better for skis or small bags. Always check the maximum weight limit your car roof can safely handle.
Mounting System
How the carrier attaches to your roof is crucial. Most modern carriers use quick-mount hardware. This system lets you attach or remove the box quickly, often with just a twist of a knob. Make sure the carrier works well with your existing roof rack crossbars. Some carriers fit bare roofs, but most need side rails.
Security and Locking
You must keep your gear safe. Look for carriers with strong, integrated locking systems. Dual-sided locking—where you can lock the box from either side—is very convenient. Good locks prevent theft and keep the lid securely closed while driving fast.
Aerodynamics and Noise
A poorly designed box catches the wind. This creates loud wind noise and lowers your gas mileage. Look for sleek, aerodynamic shapes. Many high-quality carriers have built-in air diffusers or smooth lines to cut through the air quietly.
Important Materials
The material determines how long the carrier lasts and how well it protects your items.
- ABS Plastic (Acrylonitrile Butadiene Styrene): This is the most common material. It is strong, lightweight, and resists impacts well. High-quality ABS plastic is UV-stabilized so the sun does not make it brittle over time.
- HDPE (High-Density Polyethylene): This material is often used in softer, more flexible bags or cargo bags. It is very durable and resists cracking in cold weather.
- Fiberglass/Composites: These are often found in very high-end or specialized carriers. They offer excellent strength and sometimes better aerodynamics, but they cost more.
Factors That Improve or Reduce Quality
Quality Enhancers:
- Weatherproofing: Excellent seals around the lid keep rain and snow out. Test the hinges and latches; they should feel tight and secure.
- Internal Tie-Downs: Built-in straps or loops inside the carrier help you secure loose items so they do not slide around during sudden stops.
- Gas Struts: These hinges help the lid open smoothly and hold it open, making loading much easier.
Quality Reducers:
- Thin Plastic Walls: If the plastic feels flimsy when you push on it, it might crack under pressure or extreme cold.
- Poor Hardware: Cheap plastic mounting hardware can break after a few uses. Metal hardware lasts much longer.
- Flimsy Latches: If the latches do not click firmly into place, they might vibrate open on the highway.
User Experience and Use Cases
Think about when and how you will use the carrier. If you only use it twice a year for big trips, easy installation is key. If you use it weekly for sports equipment, easy access and low noise matter more.
- Road Trips: Carriers save valuable space inside the car. Adults and children ride more comfortably when luggage is not stacked around them.
- Outdoor Sports: Many carriers have special mounts for skis, snowboards, or fishing rods. This keeps wet, dirty gear outside the clean interior of your car.
- Moving/Hauling: They are useful for temporary hauling, like carrying lightweight furniture or supplies when moving between apartments.
10 Frequently Asked Questions (FAQ) About Car Top Carriers
Q: Do car top carriers lower my gas mileage?
A: Yes, they usually do. The added weight and the extra wind resistance (drag) make your engine work harder, which lowers your miles per gallon (MPG).
Q: Can I wash my car with the carrier still on the roof?
A: Generally, yes, you can run it through an automatic car wash. However, hand washing is safer. Always check the carrier manufacturer’s instructions first, as some automatic washes can damage the straps or locks.
Q: Do I need a roof rack to install a carrier?
A: Most hard-shell carriers require a set of crossbars (a roof rack system) to attach to. Some very small, soft cargo bags can attach directly to bare roofs using heavy-duty straps, but this is less common and less secure.
Q: How fast can I drive with a carrier installed?
A: Most manufacturers recommend keeping speeds under 75 or 80 mph. Driving too fast can cause the box to vibrate, potentially damaging the box or the roof rack.
Q: Are car top carriers waterproof?
A: Good quality carriers are highly water-resistant. They are designed to keep rain and snow out. However, they are usually not 100% submersible, so heavy, prolonged downpours might cause minor leaks if the seals are old.
Q: What is the difference between a cargo box and a cargo bag?
A: A cargo box is a hard-shell, locked container made of plastic. A cargo bag is a soft, zippered bag, usually made of heavy fabric. Boxes offer better protection from weather and theft; bags are cheaper and easier to store when empty.
Q: How do I secure items inside the box?
A: You should always use the built-in tie-down straps if your carrier has them. If not, use bungee cords or ratchet straps to secure bags tightly so they do not shift or bang around while driving.
Q: Will a carrier damage my car’s paint?
A: If the carrier is installed correctly and the mounting feet have rubber pads, it should not damage your paint. Damage usually only happens if the rack is installed improperly or if debris gets trapped between the mounting foot and the roof.
Q: Can I open the carrier if it is full?
A: You can usually open the lid even if it is partially loaded, but it is strongly recommended to empty the box before opening it on the side of the road. Strong winds can snatch the lid right off.
Q: How long does it take to install a carrier?
A: If you have the roof rack already installed, a new carrier can usually be mounted and secured in 15 to 45 minutes once you get the hang of the mounting hardware.
