I have a 2001 3500 4x4 with a six speed trans and I tow a heavy 5th wheel toy hauler. When I take off, I notice alot of suspension movement on the rear end as the truck takes off from a stop with the trailer. Sometimes hopping too. I'm looking at some traction/ladder bars from Tuff Country and I'm wondering if anyone has any experience with traction bars. Do they help??? Thanks.
