Based on your question, I am thinking the pic is not from your coach and you are inquiring about getting a cabinet with a corian top that looks like the one in the pic.
If I am correct, I would say any competent cabinet shop can make that for you. CC used a lot of cherry and that looks exactly like the cherry in my coach. I have purchased cherry from a local mill shop and made a few things myself. It matches perfectly.
The folks at Country Coach in Junction City, OR can make that for you. Also, there is a place in Junction City called Carr Industries who does a lot of custom work. IIRC, the folks who ran that business now own/operate Oregon Motor Coach in Eugene, OR so you may want to give them a call.
