Fridge not cooling
We encountered the same issue with our dometic refrigerator earlier this summer on a VERY HOT weekend. The trailer was level side to side, and front to back. It had worked well at home pre-trip, but once we arrived it got HOT. We found the small, factory installed cooling fan in the back was running periodically, but not sufficient to remove the heat from the back of the fridge. I installed two small 12 volt fans on the top exhaust grid blowing out, and put them on a switch vs the usual heat sensing device. Seems to work well, and it definitely pulls air up from the bottom grid over the cooling fins.
