as you can see from my sig. i own a 01 2500 srw. i have recently purchased a 30 foot encolsed race car trailer that weighs aprox. 10k when loaded. my question is, with the lift and 37in tires i am getting a good bit of sway at highway speeds. how can i help to keep the sway down? also, i have the opportunity to purchace some 19. 5" bridgestones on rims. would this be a good comprimise for not having a dually? i currently run about 10% tounge weight with a weight dist. set up on a 8 3/4 drop shank. i am going to purchase a friction sway control for the trailer in hope that this will help. thanks!!!
