Gas Class A 37' Pros & Cons of Sway Bar and Trac Bar

If you can, do the CHF first. Then, if you think you need more control, a track bar on the rear, will keep the house from shifting over the axle when driving.

If you are bothered by side to side rocking, Timbrens or Sumo Springs will help, and may improve sudden jolts.
