The first thing I did to my 2012 fleetwood terra was the cheap handling fix. It made a world of difference in handling but the coach felt like it was going to explode over expansion joints. So I changed the bill steins to konis, and things got better. Then I added a safety steer, and things got a little better. Then I added sumosprings to the front and back. Almost all of the sway is gone now. I actually changed the chf back on the front axle to let the sumosprings handle the sway. After about 500 dollars of insulation in the dog box and under the dash I actually have a nice riding relatively quite coach. Nothing like the day I drove it home, which was the scariest ride of my life!
