I went yesterday and looked over both and played with them a little bit. The PA is just huge and has ample room for anything you would want to bring. The Outback is more compact and with less storage space. The size and transporting capabilities are what I am concerned about with the PA. The Outback wieghs about half the PA and would be easier to load and unload by myself. Drawback is loosing that extra room,stability, being able to stand, and comfort.
