Your search criteria is a bit similar to mine except I'm not retiring any time soon. Two items on you list, separate washer and dryer and the TV's, caught my attention. You need to focus your search no older than 2008. Pre 2008 the TV's were analog and it appears the combo washer/dryer were common items. Also for model years of 2011 and beyond there was a big price jump due to the new EPA requirements on the power train and the inclusion of DEF. The TV opposite the coach is going to hard to find unless you jump into 2012 and beyond. The are a couple with the TV in a book case/cabinet with a electric fire place.
All the brands you listed are solid rigs. Shop floor plans first builder second and chassis third. Although they may look the same small differences such as kitchen on the curb or driver's side as an example, can really change how livable to you and the DW the coach feels. Seen a couple with a retrofit residential fridge also. You can tell by the exterior fridge vents but there's a stainless steel model in the coach.
My search is focused on Tiffin Phaeton line. Prefer a 36' but 40' is within my budget but I'm at least a year out before I buy something. A couple of really good buys popped up after Labor Day but not so much at the moment. Maybe come Spring there might be another sell off so be ready to jump if 'The Coach' pops up.
Good luck with your search.
