I have a 2003 Pace Arrow 37ft. It had front and rear sway bars but still had to correct steering constantly. I made a track bar, there are several plans on a site called Omeys. It is mainly for workhorse but the DIY plans will work on others. I used a top link for a 3point hitch from Tractor Supply for the link between frame and rear end. Under $30. It was a little work making the plate for the rear end, but what a difference in handling now.
