Having trouble making jump to roof of truck! Babylon level

Hello everyone!

I recently restarted playing "The Infernal Machine".

Right now I am in the Babylon level where Indy is supposed to make a running jump from a ledge to the roof of a passing truck in order to get inside the base.

I am having a lot of trouble making this jump. I have been trying to make this jump for four days now without success. Can anyone advise me on where I should have Indy start to do the run/jump? Where should the truck be when I start to jump? I seem to be making the jump at the wrong moment because Indy misses the truck and lands on the short ledge below on the other side.

Thank you for your help.

stand on the ledge that has the ladder that goes up to itstand right on the edge right in the middle, hop from a standing position as soon as you see the front of the truck. I had trouble with this part of the game when I went though it.
