Well after some looking, some questions, my search is over. Went to a Keystone dealer yesterday, and found the mount that they would use if I had ordered it when purchased. $69.00.... I thought that while I was happy to find it, I saw that it was manufactured in the same city as my camper. Elkhart In. So I came home, looked it up and ordered it $25.15, problem solved....Here is the info for any that need one....thanks for the help.
