For the price, the Rola cargo basket is a great option over its more expensive counterparts from Thule and Yakima. Easy to put together. With the extension added and to be installed on a large SUV such as our Armada, a second set of hands is definitely needed to get this onto the factory roof rack/rails. I would've given the Rola 5-stars but unfortunately, they don't offer locking brackets.
We just used our Rightline Sport 3 top carrier for the first time last week. Our family went from PA to the Outer Banks of North Carolina. The bag was all we expected and more. The amount of space we were able to add to our Suburban by loading 7 peoples luggage on top was amazing! And, in our return trip yesterday, it literally rained for 6 straight hours as we got up north. We unloaded this morning...in the rain...to find all of our gear completely dry. I used ratchet straps instead!
almost great roof rack
There is a lot of good things going on like easy to install, rubber on top of rack makes things stick better. What needs improvements are better contours on the clamps and making the rack heights equal. Currently the front rack is higher than the rear, but since there is rubber on the rack, there is no slippage, just looks. Overall pretty nice.
