Does anyone have any experience on the best trailer hitch bike rack for the Model X. I am looking for a hitch that holds 4 bikes and swings out of the way of the hatch. Which is better, Yakima Full Swing, Thule Vertex or Apex, Saris, or something else? I have seen some on the forum that tilt away, but I think I would prefer one that swings to the side, unless there is some disadvantage to the swing away racks?? Also, I like to take remove my rack each time I am done using it, so I am looking for the easiest and lightest rack to install/uninstall. Thanks!
