WDH or no WDH???

Three years ago while in northern NM, we purchased a 179. I bought a 2 inch ball from a local Tractor Supply store and towed the 179 home to southern NM with my 2004 ¾ ton pick-up. The ride seemed a bit bouncy and sway was noticeable when I got caught in a dust devil. So I replaced the shocks (they were the original shocks for the truck) and added a sway control bar. The trailer connection for the sway bar was welded onto the camper frame. But the combination of new shocks and the sway bar solved the bounce and sway issues.

Last week we traded our beloved 179 for a new 195 from the same dealer in Colorado. Because this was a trade and part of the sway control was welded to the camper frame, I towed home without sway control. The tow vehicle was the same ¾ ton pick-up. It is a diesel and only has 140,000 miles on it. The ride also seemed a bit bouncier than I was used to but I figured this was due to the extra tongue weight of the 195. I feel safer with sway control although many believe I don't absolutely need it with this tow vehicle. So I am planning on adding sway control.

I am wondering whether a weight distributing hitch would dampen the bouncing as well provide sway control. If so, what make and model would you suggest?
