Viv,
I just want to add my Ditto to what Ray said earlier. A Prevost is just that, a Prevost. Little changes between them. Ray has some good thoughts on how to get you past your problem areas. Follow them.
As for mirrored ceilings, well Carole and I did not like them either. So did we run around the websites oh'ing and ah'ing over coaches with mirrored ceilings - no. Our first question about a potential coach, if we could not tell the answer from photos, was "Does the coach have a mirrored ceiling?" If the answer was yes, then we looked elsewhere.
We are also not into wine and cheese. We once were but had to give it up some time ago. So that meant we had no idea what we would do with the built in, glass front, cabinets for holding wine glasses. Scratch off that one too.
Bottom line, YOU MUST make a list of must have features as well as a list of absolutely don't want features. Anything not on or on the coach from either list is then what YOU must deal with from your budget. The other thing you might want to do is locate local resources for making modifications to your liking, and for performing maintenance on, your bought coach. Will the businesses you have used for mantenancing your previous RV's do work on a Prevost. It is worth asking the question, especially since I found out this year that Country Caoch's sole representative in NC does not feel they are "qualified" to work on a Prevost - even though what I needed work on was a Country Coach system not Prevost.
After reading this blog from its start I am beginning to understand where Steve Katz is coming from. Not that I agree with him but I do think he should give you your deposit back and move on down the road.
