With properly set up W.D. that includes sway control....either integrated or friction, you won't have any sway issues. It does take some time to get the right "recipe" for a good set up. Tongue weight and bars to match that. Proper tilt of the head. Ball height and weight/load distribution in the coach. Main thing is don't throw the towel in just because it wasn't right the first go-round. I pulled a pretty "lardy" meaning heavy, 25ft. Nomad all over the U.S. with a 1999 GMC 4X4 Suburban 1/2 ton. Never once had a sway or control issue. The current breed of 1/2 ton-ers are way better than my 1999 Burban for sure.
