I have a 2020 Allegro Open Road 34PA. I just replaced the shocks and installed Bilstien shocks on our RV along with Hellwig front and rear sway bars. What a difference in handling and really reduced the sway. The RV had Sumo springs originally installed. I also installed a Saft-T-Plus steering stabilizer a year ago.
Bilstien shocks: 24-234511 and 24-234528
Hellwig rear sway bar: HE36XR
Hellwig front sway bar: HE43RR
