I have the same bracket on my Flagstaff. Dealer said they could order me one from FR for about $30. Did not push it as my unit has a out side shelf bracket next to the tv outlet. 16 inch shelf came with unit. My issues are the coax outlet and 110 are barely under the extended awning. No watchey tv outside it there is a light rain!
