Thanks! I'll look at them more closely and probably give Thule a call. The documentation I've found doesn't show compatibility of any of their carriers to this vehicle, but then maybe it just needs to be updated.
Yes, honziss was right. I happened to run into a Thule factory rep today at REI. The newer Thule areo style bike carriers such as the Thule Paceline 527 fit just fine and are infinitely easier to setup and use than the older (cheaper) stuff. Thanks!
And the rep is supposed to get on the Thule folks tomorrow to update their website, which shows none of them work!
