I have seen both in a super duty, I recall it was in a King Ranch. I am not sure how you would mount it though.
My DVD player was from the factory and is pretty cool, the wireless head phones have two channels so one channel you can listen to the DVD movie, while the other one channel is on a radio station. All the while I can listen to Sirius over the front speakers. Pretty neat set up Ford came up with. I can also control the DVD from the front as well. Now if I can figure out how to watch the DVD up front that would be pretty cool.
