All you need to do is act wisely to enjoy the advantages of safely roof-mounted storage.
Rear Overhang Must be Avoided
The front overhang is ok. But, the overhang situation on the rear side can cause problems. Even a bit of overhang in the backside is not a big deal. However, things could turn nasty if the overhang becomes too much. For this reason, car manufacturers always recommend that customers should fit cargo boxes on the front instead of the back.

How to Reduce the Roof Box Overhang Situation?
Most people don’t like the overhang situations in their vehicles. But, are there any steps or measurements that can be effective against it? Yes! Here, we’ll discuss some solutions you can apply to deal with this problem. Let’s check –
Car Type

The right-sized roof box will indeed matter to you. If you want to have a flexible trip by car, you should buy a perfect-sized roof box. Moreover, buy the box according to the size of your roof rack. If the rack is small and you purchase a larger box, it will increase the possibility of an accident.

Do you want to reduce the drag to a minimal range? If yes, then you can reposition the cargo box. Consider not to place it too far back. Otherwise, the rear hatch can fall into a deep trouble. This is how you’ll get a fair chance to decrease the overhang on the front or backside of the vehicle.
Stability
This is another crucial thing for a roof cargo box. If your box isn’t stable enough, it can fall off during driving. So, there’s no point in ignoring it to avoid a colossal fiasco. Consequently, the right-sized box generally provides stability. But, if you buy a wider box, it could raise a problematic situation.
Nevertheless, you can purchase a widespread bar to bring stability. This is how everything will place in order. Before beginning the journey, you can run a test on whether the box is stable or not.
