Sorry for the delay in responding, 2wired - I haven't checked back in awhile....
With regard to other "innovations" to our 25' 2003 Classic, check out this link from our adventure last summer (2007): Western States 12-week trip report
. You'll find a few details there.
However, the very best source of Classic modifications on this forum is John Irwin ("Pahaska") - we replicated the shelving additions to the overhead cabinets suggested in this link which is chock full of innovations to his former 25': 2003 Classic
. He has also described (though we haven't replicated) a wonderful modification to his current 28' 2005 Classic in this link: bathroom storage
