That is one first class motorhome. An Exec, Dynasty, or Signature would be something I aspire to.
Monaco's outboard airbag roadmaster chassis is the best of the best in the "any man's RV class"
Unaffordable brands, such as Prevost and Foretravel, share that design, other affordable RV's do not.
The outboard airbag chassis sways very little in the corners, and most of that is overcome by the active air on the rear axle. They are not equipped with solid anti-sway bars, simply not needed.
