I've noticed how all industrial lots like to have a connection to other cities so that their freight trucks can move, but what good do these freight trucks really do? I don't think I get any income from them.
Just Curious?

You don't, unless they go through a toll booth on the way out. More or less, Freight simply works as a way to make IND more prosperous; it becomes stressed easier without an outlet for goods, and in addition, less likely to build. Freight connections also raise your IND development caps.
Freight trucks leaving the city also provide cap relief
