I have the Arvika 2" receiver with a Thule Crosstrack rack on our X19H. Arvika also makes a full line of racks as well, but we wanted to use our existing Thule rack. Mounting was easy, but the clearance for the spare tire (mounted under the A frame) was pretty tight.
The Arvika carrier is below the bunk end, so stays there permanently, but the Thule has to come off before dropping the bunk. A couple of pics of my setup:
