Vince, my 74's waterheater is under the bed on the passenger side. On the outside of the coach look for a removable door about one square foot with ventilation holes It's normally secured with a single straight slot fastener. John Wayne

Hey John, I found it under the bed on the driver's side. It's electric! No wonder I couldn't a vented door. Hopefully it works. I'm headed for Morro Bay for a few days and it would be nice to have hot water.
