Where to jack up the front of a SRW 2011 F350?

Big trucks usually don't have pinch points on the unibody.. Way to heavy and they have an actual frame. You would most likely put the jack right through the floor board.

That long thing you are looking at is the radias arm going front to rear. In the back, behind the front tire, you can jack from there and also from the front of it where most of your pictures are showing.
