Best Rooftop Cargo Box to Carry Your Luggage Conveniently

If you have been having a hard time carrying all your luggage in the car and feel like your boot is not enough, you need a solution. Of course, reducing your luggage isn't the solution, but what is? Think about adding a carrier to your car's rooftop. You can get the best rooftop cargo box for easier and safer transportation of whatever you may like to carry to any destination.

What is a Rooftop Cargo Box?

Installing a rooftop box on your car is like carrying a backpack for your extras when going on a trip. A rooftop carrier box is a storage box that you can install on the roof of your car to carry the extra luggage that may not find space in the boot. You can also refer to it as a cargo box or a roof box.

If you are an over-packer or your whole family is going camping, you most definitely need a roof box. A rooftop carrier is necessary as it helps you improve your organization, increases your car's carrying capacity, and adds comfort as you do not have to pile other luggage on the seats when the boot is full.

There are two main types of rooftop carriers, and they include:

a). Hard Cargo Boxes

Just from the name, I'm sure you can already tell how these cargo carriers are constructed. They are made with firm and sturdy materials. They are also compact and durable, and most importantly, weather-resistant

b). Soft Cargo Boxes

Soft cargo boxes look like huge bags with straps on; they are, in most cases, constructed with thin plastic-like vinyl or PVC. They can protect your luggage from rainwater. They are generally more affordable than hard cargo boxes, lightweight, and easier to install. Their lightweight makes them ideal for smaller cars. However, unlike the hard cargo boxes, they do not feature a very safe locking system.

Now that you know what a rooftop box is and the types available let's discuss the best five below.

Factors to Consider When Selecting the Best Rooftop Cargo Box

What should you consider before you buy the best rooftop cargo box? First, of course, if that question has popped into your mind if you consider buying this box. In that case, I would like to take you through some of the important features you need to keep in mind.

a). Vehicle Length and Hatch Clearance

Firstly, you will need to check the maximum length of the carrier your vehicle can accommodate. You don't want to buy a carrier that blocks your windshield, either front or rear, as this will negatively impact your aerodynamics. Also, it would help if you bought a carrier that will not block your vehicle's antennae or hatch opening.

The easiest way to know what size will feet your vehicle's roof is by measuring the distance between its roof rack and an open hatch and compare with the box's specs.

b). Storage Capacity of the Box

Before you buy the best rooftop cargo box, you need to consider the options available and see what you think will work best for you. For example, if you have a big family or think you will need to carry more loads, you may need a bigger carrier. For most users, 16-18 cubic feet of storage is enough to accommodate camping gear for three to four people. However, this will entirely depend on what you will be carrying.

c). Access

Different carrier boxes have different access methods, including one side, rear side, and dual access. The most user-friendly carriers have dual-sided access and lock on both sides so you can open the box from either side of the vehicle. One-sided and rear access is commonly used on budget designs. However, before going for the cheaper designs, remember that they are less convenient in reaching your gear.

d). Open/Close and Lock Mechanism

Some designs of the carrier boxes combine lock designs and open and closing mechanisms, and they work together to secure the lid to the base. This design is simple and may save money, but it is not very secure. More expensive boxes that open and closes their latch and a separate lock that secures the closed lid. They also indicate when the lid is locked, which assures you that your items are safe.

e). Wind Noise and Aerodynamics

Bulkier cargo carriers create more drag than smaller ones. More drag results in lower gas mileage and more wind noise. More streamlined cargo carriers often maximize aerodynamics than those that are box-like. Wind noise is not entirely a result of the bulkiness of the box. Much of the noise is generated when air moves between the vehicle's roof and the roof rack. When you use an empty box, the wind noise is likely to be more. Therefore, avoid traveling with an empty carrier if you are trying to lower the noise.

f). Materials and Durability

The materials used in making a rooftop box affect its durability. Most carriers are made with ABS plastic which can withstand frequent opening and closing. However, their quality depends on other factors like the mounting hardware, handles, hinges, and locks. You need to ensure that the cargo carrier you buy is firmly constructed to prevent the small parts from breaking easily.

Frequently Asked Questions About the Best Roof Cargo Carriers

1. Can I drive with an empty cargo box?

Driving with an empty box is not recommended as wind is likely to push it around and make even more noise which not be pleasant. Rooftop carriers are also known to affect gas mileage negatively. Therefore, it is better to leave your carrier at home if it is empty. In addition, sometimes the weather may be harsh, and exposing your box to such conditions when it is not in use will only lower its lifespan.

2. Where does a cargo box go in a car?

You can mount your cargo box to the trunk of a vehicle, fasten it to the truck's bed, hitch to the back or mount it on the rooftop of an automobile.
