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 are plenty of options on the market.

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.

Size Selection

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’s 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.

Storage Space

The storage space or volume inside of the roof box is measured in cubic feet. Most boxes 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.

Weight Capacity

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 constructions normally hold more than 100 LBS but all manufacturers will state the weight capacity upon 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 feature multiple curves that allows 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, purchasing from 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 the best type of cargo box for you. Hard cargo boxes are the more desirable and offer a weatherproof, durable and sleek option. However, they do come at a premium cost but they are worth paying the extra.

The alternative choice of a soft cargo carrier is a much cheaper option 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 when you arrive at your destination.

Carrier Warranty and Quality Control

The more expensive cargo boxes use high quality plastics such as ABS. This provides a rigid and durable structure for the cargo box that lasts for years to come. Poor quality materials won’t be able to withstand bad weather conditions and UV rays from the sun. This causes discoloration of the box, clips and other components breaking down. The plastic used is often thinner on the cheaper roof boxes and often rattles or cracks 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 them.

Cargo Box Ease of Use

Some cargo boxes contain more than one lock, which makes it harder to force them open by thieves. Some modern roof boxes also feature multiple opening areas, which means it can be opened from both sides and significantly improves its practicality.

Installing a cargo box will require roof racks to be installed to your car. 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 and they go underneath the roof racks and connect to the two holes in the roof box. You are then able 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.

Conclusion

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 a 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 brands such as Thule, Yakima and Sport Racks.
