Hey Sunny!
Well, you are going to get a lot of opinions which will give you info to digest. My experience is limited as we are only on our second coach.
Our first coach had the Roadmaster 10 airbag chassis. To me, although a lot of people like that chassis, it road too rough for me. I drove a Tiffin Allegro Bus before the Monaco on a test drive that had the Spartan chassis and recall it was smoother, that was 8 yrs. ago.
Are you buying new or used?
