Safest position for carseat in a SUV??

[banjo]

We just bought a Britax Marathon and are about to start having our daughter sit facing forward. Where is the safest position for us to put the seat in an Expedition? In the middle or behind the passenger seat? I haven't read anything that states either is better, but thought I'd ask everyone here. Any advice is appreciated.
Thanks,
Banjo

How old is your daughter? The Marathon is great for rear facing past a year and 20lbs. Rear facing is the safest position for anyone to ride in a car. Here is a website with more information. As well as pictures of children rear facing past a year.

To answer your question, the safest place for your daughter to ride is the centre seat if you can get a tight install.
