📋 Table of Contents
1How do I know if a roof box will fit my car?
Check your car's roof load capacity (in the manual or door jamb) and ensure it's at least 25kg more than the box weight when loaded. Measure your roof's width and length, and look for roof boxes with adjustable mounting systems that work with standard roof rails or crossbars.
2What's the difference between hard-shell and soft roof boxes?
Hard-shell boxes are more durable, weatherproof, and secure for valuable items, but heavier and more expensive. Soft boxes are lighter, more affordable, and easier to store when not in use, but offer less protection and security for long trips.
3What capacity do I actually need?
A 300-400L box works for weekend trips with 2-3 people, while 400-500L suits longer family holidays. Consider that you'll also have boot space, so a medium-sized box often balances convenience with your actual storage needs.
4Does a roof box affect fuel consumption?
Yes—expect 5-15% higher fuel consumption depending on box size, speed, and aerodynamics. Hard-shell boxes with streamlined designs have less impact than bulky soft boxes, so this matters if you're doing long-distance driving regularly.
5What should I check before installation?
Verify your car has compatible roof bars or rails, check the weight limits for both the bars and your roof, and ensure the box's mounting feet align with your roof system. Test the installation on a flat surface first and use the correct tools—improper fitting can damage your roof or cause the box to shift during driving.
