remodel of a 2000 Winnebago ultimate advantage

I'm not quite sure what you're asking for here. The cabinet hardware is generally not RV-specific in any way. If you don't like what you have, get something more to your liking and within your budget and put it in.

One decent place to order cabinet (and other) hardware is Lee Valley; they have a lot of options available. For 12V lighting fixtures, if you wish to replace them, I've looked on Amazon and eTrailer. There are, of course, many other companies selling these sorts of items.
