The front panels are totally replaceable on most all RV refrigerators. Just look carefully for screws which most likely hold the top trim on. Once you get the trim removed you can slide out the old and put anything in you want. I have used plastic laminate with good results. If it is not thick enough for the slot, add a backing to it.
Now, if the Interstate has some different refrigerator that I am not familiar with, my advice may not be worth much. But if it is a Dometic or Norcold the panels should be easily changed.
I can't imagine why AS could not help on this issue.
