Rough start, appreciate advice

One poster,I think, kinda touched on it, it doesn't seem the OP has a firm grasp on the way a truck and trailer react or relate to one another, whatever you'd call it. Does the OP have an opportunity, maybe, to go back to the school and get some fine tuning? I know he said the school was a joke but there had to be something worthwhile about it, I would think anyway. It's just a thought that something may just "click", aside from being more careful and all.
