ok- need a lil help from you guys- i just sold my 97 chevy 3500 dully- and purchased a 2001 dodge 2500 4x4 cummins deisel-- hooked up my 20ft hauler to the new truck and headed out to marysvale a few weeks ago- and anytime any bigger car or truck went by me on the highway the trailer would start rocking,back and forth--- and when a semi went by -(pucker up) it was scary! :poop_hittin_the_fan: -- i have been towing this same trailer since 01 and it has never swayed at all-- no mater what was going by me or at any speed!! im using all the same stuff on the new truck- ball,weight dist., sway bar-- nothing has changed but the truck!! i had lowered the ball to the lowest seting on the hitch, but im thinking it might still be a little to high- it still angles back a little bit on flat ground!- so what do you guys think?? can any of you do a measurement from the ground to the ball on your trucks for me-- i guess i should have measured where it sat on my old truck before i traded it in!! thx for any help or info in advance!! -
