I guess I am very luck. Had no problems with the fridge in our 2013 PC2100. Don't use a fan but did buy a pair of hinges ($15 or so I think) to carry just in case. Depending on outside temp, mine is set at 4 or 5 and works great maintaining a fridge temp between 35-40 (I have 2 thermometers in different location and one in freezer) and things stay frozen in freezer but not quite as solid as in my home freezer. I do keep both compartments quite full. If there isn't a lot of food, I put in water bottles to take up the space. That helps with opening the door. When there is not much inside, refrigerated air quickly escapes. Refrigerated water bottles stay put. I also keep some frozen water bottles in the freezer for a lot of reason. The one time we were challenged in Big Bend National Park and temps hit 112, I would put the frozen ones in the fridge and cold one is the freezer to refreeze (always as we went to bed so it would stay closed for 8+hours). Worked pretty well.
If you are operating on 9, I almost think it might be a defective refrigerator.
I aslo participated in the class action law suit and just received my second check.
