You will most likely need to get a new draw bar that is dropped by 3-4 inches or more depending on how high the trailer sits etc.. The trailer should sit level when hooked up to the truck(the antisway/load levelers help with this) and if the draw bar is too high .........well I think you can figure it out.
I disagree with Rick, the anti sway systems come in very handy when you have severe crosswinds etc. They also make it slightly less necessary to nail the front to back weight/loading ratio of the trailer. Are they necessary, no, but they sure make towing alot easier.
