When it comes to luxury SUVs, not many companies can compete with Mercedes. The Mercedes GLB, in particular, is in a class of its own. It has an impressive 27 cu ft. trunk. However, you might need to install a roof box to haul extra cargo.
Roof boxes don’t come cheap, but if you have a growing family or have a knack for hitting the road every weekend, they are definitely worth the premium bucks.
Not only do they offer additional storage room, but they make long drives safer by improving rear visibility.

Conclusion
All the above roof boxes are a perfect fit for the Mercedes Benz GLB. However, one noticeable difference is that the openings are different. While passenger-side boxes are still good, rooftop carriers with dual opening systems are easier to access no matter where you have packed your vehicle.
Additionally, during installation or removal, it’s much easier to fasten the bolts, unlike when you have only a single side opening. Nonetheless, passenger-side openings are meant to protect the user, as you can only access your gear away from oncoming traffic.
