"Suitable for fulltime living" is very much dependent on you. I know somebody who full times in a 26 footer with no slides. You really need to look at floor plans that are suitable for your needs and only then consider length and number of slides.
That said, Tiffin's Allegro Red comes with quad slides as short as 33 ft.

Are you looking new or used? There are no new Country Coaches, but I prefer used anyway.
The Monaco Dynasty is a great bang for the buck coach.
Wow! I think not many people would describe a $500,000 coach as having "great bang for the buck! Don't get me wrong - it's a gorgeous coach with a lot of features, but I never thought of it that way.
