Taken all the steps to prevent sway. Still swaying. Help!

Right away I picked up:
"I am loading the trailer with as much of the weight low and forward"
That could be your problem. Your trailer should be balanced with most of the weight over the wheels, (not forward).
Once you are hooked up to your truck, stand back and see if it is level on the same plane as your truck.
If it is down at the front, that is probably your problem.

Good luck
