Why this product
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.

The Arcos Box represents a new approach to cargo: rear-mounted instead of roof-mounted. This keeps the roof free for bikes, kayaks, or solar panels. The weatherproof hard shell protects gear in any conditions. Combined with the Arcos Platform, it tilts for trunk access.
Multi-sport adventurers who need the roof for other gear, those who dislike roof loading
Budget shoppers — the Box + Platform total approaches $1,500
The Arcos concept is brilliant and well-executed. For those who need roof space for other purposes, this is the answer.
