Question 2 - Should wind affect a good set up truck

Surprisingly, sudden acceleration can pull a trailer out of a sway event. I've done so with plenty of trailers. The acceleration must be quick and sharp and the steering must remain straight. It's easier to accomplish this with smaller trailers. Trucks pulling heavier trailers normally lack the ability to create the sudden acceleration when heavily loaded. So truck ends up accelerating more gradually which only makes things worse. Not the best method for getting under control, but in some situations it works.
