I also have a 2006 Fleetwood Bounder 35E and for the whole month of January I had no hot water to the bathrooms or shower. I spent $350 for replacement of thermostats, electronic control box, etc. and still had no hot water except for kitchen sink and then only after running hot water for an extended period of time. My exterior shower valves were completely turned off. I was told that there is no mix valve on the Atwood 10 gal heater for this model. 3 weeks ago I managed to get the motorhome to RCD in Pataskala, Ohio, spent another $145 for them to tell me there is nothing wrong with the unit. Now what do I do?
