We tow a 35' Keystone Sprinter TT w/ a Chevy 2500HD. 6.0l, 6sp trans, WD Hitch & Stabilizer. The trailer is 8400lbs dry and we are about 10,500lbs loaded. The truck pulls the trailer very nicely with very little sway, except when a Semi comes blasting past, then there is some wiggle. Very happy with the set up.
