Have an IOTA 4 stage automatic charger (in the large bay). There are no panels or other equipment in the coach to tell me it's working or not, and what the state of charging is. I know it IS working by the batteries getting a charge from the Gen. Only way of seeing the state of charge is through the Javelina at the back-up camera. <br/><br/>I intend to install a Renogy 400W kit...
