There is no comparison to the way my Magnitude (Omni) SV34 rides and handles compared to my previous I coach... an Outlaw 29H on an E-450 chassis.
The difference is night and day all the way around.
The F-550 is meant to be a true heavy duty truck chassis and can handle the length, height and weight of a motorhome much better than a van chassis
Any motorhome over 25 feet on a van chassis is going to be too much for the stock suspension and it will need upgraded sway bars, steering stabilizer and Sumo Springs to get it to ride and handle properly.
An F-550 suspension handles a large motorhome body much better base on my experience.
