Cargo Box Buying Guide
Roof cargo boxes have become far more advanced over the years and are available in multiple designs. Whether you place the box upon a pair of roof rack cross bars or use a soft carrier bag that loops through the car, there is plenty of choice.
When choosing a roof mounted cargo box, you must consider the aerodynamics, weight, cubic capacity, quality and ease of use.
To help you make an informed buying decision, we have produced the below guide regarding roof cargo boxes.
The size of the roof mounted cargo box is highly dependent upon the type of vehicle you drive. For example, you wouldn’t want to choose a roof box that is longer than the roof of your car because it will overhang.
Another factor that you may consider is the height because many parking or building entrances have height restrictions. For large vehicles such as SUV’s, this can be an issue but many manufacturers offer low profile designs for this exact reason.
The storage space or volume inside of the roof box is measured in cubic feet. Most boxes will range from 10 to 20 cubic feet, which is more than ideal for most road trips. The additional space is a major requirement for many families and the cubic feet measurement is the main figure you want to look out for.
The weight capacity that the roof box can handle is often forgotten about and can cause issues. Piling as much luggage as possible into the box to the point that it exceeds the capacity can result in cracking of the box.
The quality of the roof cargo box is often seen by the amount of weight that it can handle. Rugged ABS construction will normally be able to hold more than 100 LBS but all manufacturers will have the weight capacity listed on the box.
Design and Aerodynamics
Cargo boxes are available in multiple designs and they have become more advanced over the last few years. Rather than being large boxes on top of the car, they now include multiple curves to allow them to be as aerodynamic as possible.
Adding a cargo box to the roof of your car significantly reduces the miles per gallon and introduces extra wind noise. Therefore, a brand that has spent years of research and development improving the aerodynamics is worth paying the extra for.
Hard vs Soft
Depending upon your budget will determine which is the best option. Hard cargo boxes are the more desirable and offer a weatherproof, durable and sleek option. They do come at a premium cost but they are worth paying the extra.
The alternative choice of a soft cargo carrier is much cheaper and can be installed without the use of roof racks. However, they do lack aerodynamics and many aren’t entirely waterproof, which can result in wet luggage.
Carrier Warranty and Quality Control
The more expensive cargo boxes will use high quality plastics such as ABS. This provides a rigid and durable structure for the cargo box that will last for years to come. Poor quality materials will not be able to withstand bad weather conditions and UV rays from the sun. This will cause discoloration of the box as well as clips and other components breaking down. The plastic used is often thinner in the cheaper roof boxes that can rattle and crack within cold temperatures.
Many of the premium brands such as Thule, Yakima and SportRack offer excellent warranties on their roof boxes. This means that they have great confidence with their products and so should you when buying.
Cargo Box Ease of Use
Some cargo boxes contain more than one lock, which makes it harder to force open by thieves. Newer roof boxes may also have multiple opening areas that means it can be opened from both sides, which is highly practical.
Installing a cargo box will require roof racks to be fitted. The locks that are often used to attach roof boxes come in the form of U Bolts, Quick Locks and Power Clicks.
U Bolts are fairly common where they go underneath the roof racks and connect to the two holes in the roof box. You then screw them tight from within the roof box. Quick Locks are similar to U Bolts, however they have a clamp that holds the lock in place. Finally Power Clicks are usually part of the roof box, which grip onto the roof box, which is then tightened by twisting a disc.
Installation of a roof mounted cargo box is fairly simple and they are far better than they once were. Rather than squeezing everything into the car, you can enjoy a more comfortable drive by making use of the roof box.
All of our recommendations offer various sizes or shapes and are suitable for multiple budgets. To avoid disappointment, we advise that you stick to the best cargo box brand such as Thule, Yakima and Sport Racks.
