Need Refrigerator Advice

[hblosser]

We have a 2015 Montana 3610RL with the Norcold 2118 RV refrigerator. For some time, it has not been able to keep things cold when the outside temps reach 80 or over. I've done all the normal things like extra fans inside and outside. Nothing helps much. We're planning a long trip out west in July and we've decided to stop at JC Refrigeration and have our refrigerator cooling unit replaced.

The question is which option to choose. My wife likes the idea of keeping the AC/Propane unit so the controls all work the same. The folks at JC Refrigeration are recommending their new 12 dual compressor unit. They have said that although their AC/Propane units are much superior to the originals, they will still have difficulties when temps reach 90 for more.

We already have dual batteries and could easily run the 12 volt unit. However, keeping the wife happy is also important. Does anyone have actual experience with either of the two options?
