If you are not in a hurry you may be able to order one from keystone. Go to any Keystone dealer and see if they will order it and have it shipped to them in the next trailer they receive from the plant. I have not done this myself but have heard that the shipping costs more than the shelf. If the dealer won't do this for you ... you don't want to deal with them anyway.
