I had the same problems with the Dometic 1350. Put high output fan outside to pull more air through, put a usb fan in top of fridge, made sure center flap was closed. Still would get in low to mid 40's on hot days. Finally went to JC Refrigeration in Shipshewana and had a 12 volt dual compressor cooling unit installed. 101 degrees today and fridge is at 34 degrees. Couldn't be happier with JC.
