I can't seem to get my fridge to stay cold enough unless I'm plugged. I added a additional fan after contacting GD and they said there was some issues with the Atwood product. I'm unable to stay under 45 degrees when I'm traveling from point to point. I use gas when driving but still not able to stay cool enough. Any thoughts would be appreciated. I also have to keep the unit set on its highest setting to keep it at 40 degrees.
