Rodesia,
I have a 2018 Fleetwood Bounder 35K...…………..Here's what I did to solve the poor handling (being blow all over the road by passing semis & winds, cornering leaning, etc.) I installed (1) Roadmaster Steering Stabilizer (2) Cheap Handling Fic (CHF) that is adjusting the front & rear stabilizer factory bars from the front end bar link outside hole to the inside hole. (had to replace the front factory end links with adjustable Hellwig end links. (3) installed a rear UltraTrac Tack Bar (4) installed an additional Roadmaster rear anti sway bar....
My shocks were fine since the coach is new...……… The above vastly improved the handling!!!!!!
