Thoughts on towing with a Ford Explorer

[mustangboiler]

I found a good deal on a 2004 Ford Explorer w/ 4WD and has a 4.0L V6. I have a '91 Prostar which weight roughly 3200 pounds, the hitch on the back is rated for 3500. Anyone have any experiences on towing with something similar? I would prefer something with a V8, but this is a pretty good deal that would be more than worth while.

Thanks!
