Problem solved, removed the main switch/control panel inside the RV and found a 3amp inline fuse to the rear awning light that was blown/not working. The layout of the switches leaves something to be desired. Just a heads up to others, the fuses in the main electrical panel 12v/120v are not the only fuses in the RV. My 3160RL has two inline 3amp fuses (one for front and rear awning lights) behind the main control panel in the hallway.
