Why this product
Why the Thule Arcos Box L?
Here's the thing — the Arcos Box L mounts behind your vehicle instead of on top, which means zero impact on fuel economy and your roof stays free for bikes or kayaks. At 61 lbs with 110 lb capacity, it includes Thule's SlideLock security. The downside? You need the Arcos Platform sold separately, and the hitch-mount design means you lose rear visibility and backup camera functionality.
