We might be able to offer more assistance if you could tell us a little about your planned usage. For example, how many people will be travelling (adults/children), do you plan to do a lot of dry camping or mostly with hook-ups, long extended trips or short trips. Stuff like that.
I can tell you that for our family of 6, the dual sofa, dual slide Class A motorhome we purchased 10 years ago is a near-perfect match for the way we use it. Of course, it took us about 2 years of research to find the perfect floorplan for us, but we ultimately did. (This is our first RV of any type.) We went from looking at small pop-ups to tow behind our minivan, to travel trailers being towed by a full-size van, to class C's and ultimately Class A's.
Take your time and know what you want and need.
Good Luck,
