As others have said the same thing already, payload is the limiting factor on 1/2 pickups far before actual towing capacity. A 9500lb loaded trailer should have around 1200lbs riding on the tongue. Consider you have to account for people in the pickup and your stuff in the back of the pickup then you will be over weight. I'm sure the Toyota will "pull" the trailer no problem after all it just recently pulled the Space Shuttle right?
In short, you don't want to overload the rear axle on the pickup - you leave your self open to tire blowouts on the truck and real braking issues to get that massive beast stopped.
