We have exactly what you need for a roof rack and cargo box for your 2018 Mercedes-Benz GLS 550 so you can carry all the gear you need on your road trip. Let's start with a roof rack, and the best option is from Thule and consists of the following parts:

- Thule WingBar Evo Crossbars # TH711420 (Black) OR # TH711400 (Silver)
- Evo Raised Rail Feet for Thule Crossbars - Factory Raised Rails # TH710401

I really like this Thule rack because it is easy to use, the bars are super quiet, it is highly durable, and on top of that it has a fantastic look. What this rack does is allow you to get to your destination with every item you need, quietly, and with style.

For a large cargo box, I highly recommend the Thule Force XT Rooftop Cargo Box # TH6359B.

This cargo box gives you 22 cubic feet of cargo capacity and is designed with a long trip in mind with its aerodynamic shape that will slice through the wind. It has a lid that opens from either side of your car to make it easy to access, and stays open until you choose to close it, so you aren't trying to put in or remove gear with one hand while holding the lid open with your other hand. Installing it on your roof rack is super easy as well; the Force XT simply uses a clamp that grips the sides of your crossbars.

The cargo box comes with locks, but the roof rack does not; I recommend getting the six pack of Thule One-Key System Lock Cylinders # TH450600 to make the rack and cargo box all use one key. I have added links to video reviews for you to check out as well.
