I just posted a new ad on Airstream Classifieds.
This is the Thule Big Mouth (model 599XTR) and it holds a single bike. No wheel removal is necessary, and it fits frames up to 3 and 1/8" in diameter. The dual-locking design locks the bike to carrier and carrier to rack; it clamps to all cross bars. We purchased it new from the Jeep dealer when we purchased our 2014 Jeep Grand Cherokee last year.
Why wasn't it used? Well… we mounted the carrier on our Jeep GC roof rack, only to discover that it was going to be too high for either of us to easily lift and remove the bicycle from an upright carrier on top of the 4x4 Jeep. So, back into the box it went… unused.
(Our solution to our "vertical challenge"? Leave the bicycle at the Tucson winter house, and buy a used bicycle at the Washington state summer house - no bicycle carrier needed!)
We are not able to ship, and it would need to be picked up from our Tucson home by the end of April.
Asking $99 or best offer -- prices on Amazon range between $126 and $149 (with shipping); we paid $130 at the dealer.
You can contact us by filling in the form on the right hand column of the ad listing:
