I would suggest calling a Dutchmen dealer. Or, contact Parts@dutchmen.com
. You may be able to give them your Vin number and they can match the doors with the same wood work. They may also, have an idea of what hardware that could be used depending upon how it has to open (vertically or horizontally).
We had a K-Z unit 10 years ago and K-Z was able to give me a raised panel door for a cabinet where there was none. The door was a perfect match. They were able to do this off my Vin.
