My Top Picks

The [Thule Motion XT Rooftop Cargo Carrier](https://www.amazon.com/s?k=Thule+Motion+XT+Rooftop+Cargo+Carrier&tag=thetestedhub-20) is my overall winner with dual-side opening, a tapered nose for great aero, and bombproof clamps. The [Yakima SkyBox Carbonite Cargo Box](https://www.amazon.com/s?k=Yakima+SkyBox+Carbonite+Cargo+Box&tag=thetestedhub-20) is the closest competitor and a great pick if you find a better deal on Yakima crossbars. For budget shoppers the [INNO Wedge Plus 660 Cargo Box](https://www.amazon.com/s?k=INNO+Wedge+Plus+660+Cargo+Box&tag=thetestedhub-20) delivers shockingly good build quality at a fraction of the premium-brand price. The [Rhino Rack MasterFit Roof Box](https://www.amazon.com/s?k=Rhino+Rack+MasterFit+Roof+Box&tag=thetestedhub-20) is the easiest to mount solo thanks to its quick-tower clamp system. Finally, the [SportRack Vista XL Cargo Box](https://www.amazon.com/s?k=SportRack+Vista+XL+Cargo+Box&tag=thetestedhub-20) is the highest-volume pick at eighteen cubic feet and the right buy for families packing for a full week away.
