Rated 5 out of 5 by from Welcome to the Big League You can stow anything in this bad boy. I love mine. I used it to go to the Grand Canyon and had all kinds of stuff packed up in the SkyBox. It's easy to install and is quiet on the road. Note to self: Do not get inside the box to show your son that it can easily fit a grown man with room to spare. Hypothetically speaking, you could be trapped inside until you figure out how to unlatch it from the inside. But I would never have done such a ridiculous thing. BUY IT!

Rated 4 out of 5 by from Holds everything - Nordic, blankets, broom, etc. I have brought this to spokane, tri-cities, and now hope to go to white pass this week. It makes my suburban height at ten feet, but if I pack it right, no sliding around. It is quiet on freeways and easy to put on and off. I needed a three step ladder. I let REI install it and it took them with rails about one hour. Sweet!

will the skybox 21 carbonite cargo box fit a 2017 audi Q7 with factory cross bars

Asked by: ski nuts
Yes.... My friend has one for his Q7. It sits high on the vehicle due to the bars but he loves his.

I have a 2016 Jeep Grand Cherokee, have the factory MOPAR crosbars installed. Also have sunroof and rear hatch door. What is the longest SkyBox (21, 18 or 16) that will fit and not interfere with rear hatch door opening or the sunroof opening.

Asked by: Willie
To determine hatch clearance, position your front crossbar in the foremost position and measure from center bar to open hatch. The clearance needs to be at least 52" for a Skybox 16 or 57" for a Skybox 18 or 21. Detailed fit information for your vehicle is not available in the Yakima Fit Guide. We recommend contacting the vendor directly for additional details.

Any experience in attaching this to the factory roof rack & cross bars on a 2012 Toyota 4Runner? Does it have any contact with the aerodynamic antenna at the back end of the vehicle's roof?

Asked by: Grandpa Steve
Yakima's fit guide does not list any of the their boxes as compatible with your vehicle's factory cross bars.

I have a 2005 Ford Expedition Eddie Bauer Edition. Will this box fit on my factory bars on top of my vehicle? Will I need to purchase accessories for this box to attach it to the crossbars?

Asked by: REI Member Sheridan
According to Yakima's fit guide, this cargo box is not compatible with the factory cross bars on your 2005 Ford Expedition. You would have to remove the factory crossbars and purchase the following items to make the box fit. https://www.rei.com/product/102596/yakima-timberline-towers-set-of-4 https://www.rei.com/product/102597/yakima-50-corebars-pair

Will this box mount on the hobie double double kayak trailers center mounting rack (additional purchase for center mounting)

Asked by: Allenbigdog
Hobie says that their trailer tower can accommodate most Thule and Yakima cargo boxes. These boxes have universal mountings that are designed to fit a wide variety of bars up to a 42" spread. However, Yakima does not provide a fit recommendation for that trailer, so we encourage you to contact Yakima directly to verify compatibility.

This item says nothing about needing ANY other components to install, so I assume it comes with all the equipment needed to install on my vehicle, is that right? If not, why wouldn't you say something, anything, somewhere on this page about that?

Asked by: TheTraveler
This cargo box attaches directly to crossbars with the included mounting hardware. We recommend entering your vehicle information in Yakima's online fit guide to make sure it is compatible. http://www.yakima.com/fit/partner/?partnerId=9&location=http://www.rei.com/b/yakima

Will the Yakima Skybox 21 fit on a 2005 Chevrolet Suburban (using the factory cross bars) and also a 2013 Lexus RX 350 (using its factory crossbars)?. I would like to switch from each of these vehicles without having to install custom roof racks.

Asked by: craigspin
The SkyBox 21 Carbonite Cargo Roof Box will fit the factory crossbars on both a 2005 Chevy Suburban and a 2013 Lexus RX 350.
