Question:
I have a 2021 ford explore limited and i am needing a roof rack cargo box for duffle bag and suitcases and other miscellaneous things. Mostly luggage. I am wondering if the factory side running rails are sufficient or do i need other rails to mount a box. And what box would be a best fit for what i need to store.

Hello Jared,
Great question!
The cargo box won't be able to mount directly to your factory-installed raised rails that run front to back (please refer to the image I’ve attached).
To make it work, you'll need the Thule WingBar Evo Roof Rack for Raised Rails - Aluminum - Black - Qty 2 # TH45ZA, which will attach securely to your factory rails. Once that's in place, you'll be able to mount the Thule Force 3 Rooftop Cargo Box - Large - 16 cu ft # TH67SA to your roof without any issues.
Getting geared up for a big trip? If so, where are you headed?
