What Factors Determine If A Roof Box Can Be Left Mounted On A Car?

So, you’re thinking about turning your car into a mobile storage unit with a permanently mounted roof box. But before you go ahead and make the commitment, there are a few things to consider.

First and foremost, you’ll want to make sure your car can handle the extra weight and bulk. No one wants to be that person driving around with a roof box so heavy it causes their car to tip over. And let’s not forget about that whole “maximum weight capacity” thing – Thus damaging your car’s roof or suspension because you were too lazy to take the roof box off.

Size is another important factor to consider. A roof box so big can obstruct your view or causes your car to look like it’s constantly trying to do a headstand. And let’s not forget about aerodynamics – if your car is struggling to drive in a straight line because of a giant roof box, you might want to reconsider your decision.

But perhaps the most important factor to consider is your car itself. Some cars just aren’t meant to carry a roof box, so it’s important to check with the manufacturer or a mechanic before making any permanent modifications.

Also if you live in an area with extreme weather conditions, you’ll want to take that into consideration as well. A roof box may not be the best choice if you’re constantly dealing with extreme heat, cold, or heavy winds.

Plus, it’s a lot more secure than a box that’s constantly being mounted and dismounted.

But let’s not forget about the ultimate perk of a permanently mounted roof box: extra storage space. Whether you’re a family with a ton of gear or a traveling adventurer with an excess of luggage, a roof box can give you all the space you need to store all your stuff. And let’s be real, who doesn’t love having a little extra room for all those unnecessary trinkets we just can’t leave behind?

One major factor is the wind noise. If you leave a roof box on your car permanently, it can create extra wind resistance and drag when you’re driving, which can lead to some serious wind noise inside your car.

Yet another pretty hefty downside. Not only are they a shiny, beaconing invitation for thieves to come to pillaging, but they also have the potential to give your car’s roof and suspension a good ol’ beatdown. And let’s not even get started on the whole sunroof situation. Can you imagine? A permanently mounted roof box blocking out all that sweet, sweet sunshine? Tragedy.

But fear not, dear reader, for all is not lost. There are ways to mitigate these risks. If you’re worried about theft, you can either remove the roof box when it’s not in use or store it in a secure location. And as far as wear and tear go, just make sure to choose the right size and shape for your car, follow the manufacturer’s instructions, and regularly inspect and maintain both the roof box and the roof rack.
