Yakima Skybox Pro 16s - Titanium
Love the Yakima Skybox Pro 16s. It's more rigid than the regular skybox, the Titanium color was a nice middle ground between the Silver or Black.
Experienced no vibration with the Skybox Pro 16s. Very minimal noise even at highway speeds. In fact, driving with the box was less noisy than drving with just the cross rails and no box.
The size is great for small to mid-size vehicles. The 16s is able to hold modern hyperbolic shape skiis (shorter than older straight skiis) with snowboards and plenty of other gear.
Just don't exceed vehicles roof weight limitations and you'll be fine. The height allows for greater storage versatility compared to some of the lower profile boxes.
The lock mechanism could be better, but overall I thought this cargo box was superior to other brands and shapes I had looked at. The clamping system to secure the box to the roof rails was quick & easy to use, extremely secure and better than found on other brands.

Yakima SkyBox Pro 16s
Works great on my Tahoe. Glad I did not get the 18 it would have been to big....It is awkward to store on the wall hanger I purchased from Yakima, but other than that it was a good purchase.

Used for suitcase on 2009 GMC Acadia
I bought a new 2009 GMC Acadia and found that I didn't have enough suitcase space for 6 vacationers. We were able to put 2 medium suitcases and one small suitcase in this luggage carrier along with our beachtowels. The box fits well and the 16S Yakimaa Skybox Pro doesn't interfer with the antenna. Just keep in mind that Yakima recommends that you sit this on the GMC cross rails that have to be purchased from the dealer. These rails are recommended for 200 lbs and the box weighs about 47 lbs. We heard no wind noise and were very pleased with the ride.
