My 2 cents, coming from our last RV (a F53 chassis Bounder 32) .
My coach was starting to get sloppy and VERY bouncing as time progressed ( around 7 years old at the time) So we replaced the rubber sway bar bushings and end links with with urethane bushings and also replaced the stock shocks with Bilstiens , but the ride didnt improve. After many conversations with F53 owners, we took it to the local spring shop and discovered the coach was sitting 2.5" lower in the front and 3.0" lower in the rear from stock ride height. Thus the front springs were almost flat and were traveling in both directions from the center line = Very bouncy ride.
Bottom line, had all 4 springs re arc'd and then the coach rode like new again, maybe better.
Good luck,
