Unhappy Buckboarding on Concrete Roads

I have a 28' Safari S/O that I am pulling with a 3/4 Dodge Ram and I have a lot of buckboarding (jouncing) when I drive on concrete roads at highway speeds. I have a Curt weight distribution hitch with sway control.

I have tried different tension on the weight distribution hitch with little only a little improvement when I lighten it up.

Any suggestions, or am I going to have to live with it and slow down below 50mph.

Elliot

Hard to avoid those roads sometimes. At least I know my regional bad ones and I do detour around those.

Yep search on "Porpoising."

We were dealing with this with our 2012 F150. With advice from the forums and my WD hitch manufacturer I a) lowered the nose of the trailer a bit b) got the inflation on all my tires exactly right and c) dialed up the WD on my hitch. It is much better. I have been considering, on the recommendation of others, firming up the suspension with either Bilstein shocks or the Roadmaster Active Suspension (leaf-spring helper). For now I think it is solved so I'm staying with the stock set up which now other than the worst roads drives very nicely.

I found Paula Ford's post #7 on this thread very helpful:

Good luck!

Sections of I-5 between Tacoma and Seattle are really bad. Lots of the pads have sunk on the leading edges and there is nothing you can do. They have(DOT) been grinding some of the worst sections (Southcenter Hill) down and this has helped tremendously.
