I have a Yakima Kingpin 2 for a 2" receiver. I could have went with something cheaper, but I have their roof rack and I've been satisfied with the quality so I decided to go with them for the bike rack as well.
Next time I buy one, its going to be something that swings away from the back. Yakima has a couple... the Fullswing 4 and the Backswing 4. The Kingpin swings down away from the door, but you can't really do that with the bikes still on the rack.
You can find a lot more information on other racks at
