Personally, while I have great appreciation for a Prevost chassis, I’ve never seen what I personally considered a tasteful interior that isn’t just filled with bling and sparkle.
I prefer more toned down interiors. Matte or semi gloss finishes. I enjoy really good tile work but every time I have seen pictures of the interiors of these things I just choke on the gaudiness of it all. Reminds me of the interior of a party bus. I want people to feel welcome in my home on wheels and not gob smacked by all the pomp. If people are afraid to touch anything or even sit down, it’s too much. I know I would feel intimidated in some of these things the way they are decorated.
Alas, to each their own I say! If you love it and it’s yours, that is all that matters.
