Badog62, I don't think the factory will answer directly on the forum. However, other owners may chime in with ideas and experiences. I have the same fridge in my Big Country, we will have it a month (fulltiming) in just a few days. I notice ice forming on the back wall already as well.
I have two thermometers hanging in the fridge and freezer. Our freezer runs around 10-20 degrees most of the time. The fridge section runs between 20-30.
The unit Is set at 5. If I make it lower, stuff freezes in the fridge. If I make it higher, the freezer gets warmer (out of the "freezer" range on my thermometer, over 20).
