XCargo rooftop cargo carrier, dimensions 50"X35"X21". Thule manufactured this cargo carrier for Sears, it has been extremely durable for me and will continue to be for the lucky person to purchase it! You will not be able to find this kind of space for this cheap. See pics on craigslist or PM me:

Price is negotiable, I will take a reasonable offer. Also willing to deliver in the Denver/Arvada/Golden area on Friday (would consider going up to Boulder or other surrounding area, but for a fee).

Have been using this occasionally, as it fits an Organic Big Pad perfectly on the bottom and all my camping gear on top of that. This is extra roomy! I'm upgrading to a Yakima Skybox for the extra length, so I no longer need this.

I have kept this in excellent condition, stored indoors, only put on my vehicle when I needed to use it. No leaks, dents, or dings.

Two sets of mounting hardware, one for regular bars and one for new-fangled wider aero bars.
