Expert Reply:
The largest Thule cargo box that will fit your 2018 Jeep Grand Cherokee is the Thule Motion XT Rooftop Cargo Box - 22 cu ft - Titan Glossy # TH629907.
If you want a Thule roof rack that is compatible with your 2018 Jeep Grand Cherokee that will be compatible with the Thule Motion XT, I recommend the following system:
- Thule WingBar Evo Crossbars - Aluminum - Silver - 53" Long - Qty 2 # TH711400
- Rapid Podium Feet for Thule Crossbars - Fixed Point - Qty 4 # TH460R
- Fit Kit for Thule Podium-Style Roof Rack Feet - 3142 # THKIT3142
