94-96 Excella vs. 97-01 Excella vs. 01-05 Classic

Hi there! My wife and I have decided to go full-time into an AS (would need to be a 30' model or so) and we've pretty much narrowed it down to either a 94-96 Excella, 97-01 Excella, or a 01-05 Classic. We're planning on stripping the interior and doing our own cosmetics, but I would really like a widebody, newer windows, and newer systems.

So the question is then, what are the significant differences between these generations? I'm talking frames, how the windows open, system logistics, that sort of thing. We just want the most stable of platform. Thank you so much!!
