How to choose the right car box – for your vehicle

Planning your next adventure and need extra storage space? Whether you’re heading to the mountains with skis, biking through trails, camping under the stars, or just need more room for gear and tools, choosing the right cargo box can make all the difference. Here’s a practical guide to help you find the perfect cargo box for your needs.

Why choose a rear-mounted cargo box?

Instead of traditional roof boxes, many travelers now prefer rear-mounted cargo boxes (also called backboxes). Why? Because they offer:

Easy access: Positioned at waist height, you don’t have to climb or reach awkwardly to load or unload gear.
Universal mounting: Many rear boxes, like IXTAbox, mount directly to your car’s towbar and fit a wide range of vehicles without complicated roof racks.
Better aerodynamics: Mounted low and at the rear, they reduce air resistance, improving fuel efficiency and reducing wind noise.

Step 1: Consider the size and shape

Choosing the right size is key. Too small and you won’t fit all your gear; too large and it becomes difficult to handle or could affect your driving.

Capacity: Aim for a box with at least 350 litres if you want to pack travel bags, helmets, or medium-sized gear comfortably.
Length: If you carry long items like skis, choose a box with sufficient length but be mindful of the box width relative to your car (avoid boxes wider than your vehicle).
Shape: Look for a box with practical, consistent volume rather than awkward curves that limit usable space.

Step 2: Check mounting compatibility

Not all cargo boxes mount the same way. Some attach easily to your car’s towing hook, like IXTAbox, while others require additional mounting kits and tools.

Ensure the mounting system fits your car.
Check how easy it is to attach and detach the box if you plan to use it seasonally.
Consider if it allows trunk or hatch access when mounted.

Step 3: Accessibility matters

A rear cargo box should be convenient to use:

Trunk access: Can you still open your rear door or trunk fully with the box mounted? Some models have adjustable heights to make this possible.
Lid design: Check how the lid opens — a wide opening angle and the ability to keep it propped open ease loading and unloading.

Step 4: Safety and lighting features

Safety on the road is crucial:

Look for cargo boxes with integrated external lights (brake, position, and indicators) that connect to your vehicle’s tail lights.
Internal LED lights help you find your gear even in dark or winter conditions.

Step 5: Extra features and organization

Some cargo boxes come with rails on the lid to mount bike racks, skis, or extra luggage.
Internal dividers and storage bags keep your gear tidy and easy to access.
Consider if the box can be used off the vehicle as a storage container.

Step 6: Load capacity and durability

Make sure the box can handle your gear’s weight. IXTAbox, for example, supports up to 100 kg, significantly more than many competitors.
Choose boxes made from durable, weather-resistant materials like aluminum or stainless steel for long-lasting performance and easy cleaning.
