I have often wondered if the rear axle movement (wrap or just back/forth movement in response to trailer forces) contributes significantly to the chucking. The one thing that I can't easily explain is the frequency of the back/forth "chucking" feeling on driver and passenger appears to be much faster than I would think a trailer hitting road imperfections could generate. Considering it happens as much or sometimes more on smooth roadways is puzzling to me.
Gary, this is the action that I am thinking of. For those who think you are just cruising along with no axle wrap remember your fuel mileage most likely went from 18 or 20 MPG empty to 8 or 10 MPG pulling that 16K trailer. Your engine is working and pulling big time. If you get that 16K lbs pushing and then pulling on your truck something is going to move. It might just be axle twisting against the leaf springs.
Understand that I am not saying this is the cause of all chucking but it might be something that is being overlooked in the search for a cure.
I never thought about the axle twisting. Maybe give some traction bars a try.
