Get your truck and trailer level when hooked up. The tongue should not be 'high', but a little 'low' (and ball) when unhooked. When everything is hooked up and pulled up tight, the lifting of the tongue and ball, to make the the truck and trailer level, will throw weight to the front of the truck and to the back of the trailer. You tongue weight is fine, don't lose any sleep over it. If you have a sway problem put another sway bar on it. I run two on my unit.
