I put a Saris Guardian 3 trunk mount on the trunk of my MSP, it too clears the wing.
Pants and I had this conversation on the toprotege.com website.
No problems so far, and I carry a 2003 Klein Palomino Race Disc on the back. It weighs about 27 pounds.
I just got a digi cam, so i'll take pics next time it's on the car.
I was thinking about a trailer receiver, but decided against it due to cost and the fact that i will never be towing anything with the MSP.
Got a demo from Rack Attack for about $120 CDN.
Happy trails!
