Well obviously I was lacking in the attention to detail department and when I thought I'd turned on the battery discount I'd actually deactivated it and vice versa...bottom line dealership said changing the battery wouldn't cause the pairing to be lost. So once the camper actually had power all was fine!! But lots of lessons learned...the pairing switch for the new controller is under the set to the cabover bed, and I figured out how to manually override the two slides. So not a total loss...anyway thanks for all the help everyone!
