Hello everyone,
I wanted to share my current roof rack and box setup.
Rack:
OEM roof rack
Box:
Thule Motion XT L Cargo Box
I chose the Thule Motion XT firstly because the glossy black matches the shadow line package perfectly. It is very spacious and can be opened from both sides. Comes with 2 keys to keep it secure. It is very simple to attach to roof rack, simply have to turn 4 knobs on the inside to clamp it to the rack.
If people are considering larger box, XL will likely fit but will hang over the windshield.
