If you are not wanting to buy new, find a used camper with the floorplan that you like and paint the cabinets a really nice off-white or white, change out the awful window valances (who in the world designed these nasty things) and you will have exactly what you want. Take the doors off, lightly sand the cabinet and spray them. Use light coats and spray them numerous times. Finish them off with a coat or two of polyurethane.
Yes, this will take you a while to do, but when you get a new camper, you will always want to do some things to it to make it yours.
Just my suggestion.
