2014+ RAM 2500 owners: have you stopped the sway?

We had a Ram 1500 Big Horn with the rear coils. They are known to ride almost like Cadillacs unloaded. With the heavy travel trailer I was getting a mushy feeling at the rear so I added a set of Timbrens. They fixed the problem but without the trailer, the truck was almost uncomfortable to drive so I removed them and sold them. Separation joints on bridges were ridiculous !
