I have to agree with "John & Angela".....having the residential refer really hasn't changed our way of camping. Typically, both before and after our refer install, I ran the generator in the morning to for about 1.5 - 2 hours due to TV and heater use. With the addition of the refer, the time didn't change. We almost always ran it for about an hour around dinner time.
"Executive"....about 12-15 seconds on the ice cream, depending on how big a bowl you eat. The ice in the door also is a little noisey when the wife goes to bed....so I add water from the door first!
