The best I have seen our freezer is 9 degrees F, which is -13 C. I have never seen a normally operating absorption refrigerator freezer in these rigs much colder than that. What may be happening is your fridge is operating without any control and does not shut down when it should. You should at least check to see what number your fridge is set at. If it is at 9, then you should set it to maybe 5 to see where your temperature goes to. 9 is coldest and 1 is warmest.
