Amen on JC, what a difference...solid ice cream! Wish I still drank beer, it would be cold!

If I change I will go 12VDV for sure. They seem to have a pretty good track record from what research and reading I have done. They also are pretty reasonable on their install rate if one does not mind making the trip out to see them.

Amen on their install process. Well worth the trip. We were pulled into the garage at 6 AM and we were out by 7:20. The fridge was already down to 37° when we left

I have been fighting my Norcold 2118 to cool like I needed/wanted it to since 2018 when we purchased our Solitude 377. I thought I had pretty much tried everything to include tear it out and reinstall per the manual specs with clearance, insulation, baffles ect. Two years ago I added the Beech Lane dual thermostatic fans into the upper vent and it worked pretty well until last fall. While boondocking in Moab I could not get it to cool below 40 degrees on gas or electric no matter what I did. Fast forward to last week as I was getting it ready to head to Arizona for Spring break with my girls.

I added some fans to the fins inside the fridge. This is the Beech Lane kit that I hard wired into the fridge 12v. I have also had issues with the thermostatic switch with the three fans on the back of the fridge. I decided to bypass that and add a programmable thermostat for the fans. I used a simple 12v off Amazon

I added pigtails so I could hook it directly into the factory fan wiring harness. I set it to come on at 95 degrees and off at 80 degrees. Temp probe is same place as factory temp probe on fridge.

I have never had the fridge work so well. Granted it was only 85 degrees where we were at but I only ran the fridge on setting 4. These are my temps inside the fridge and freezer as well as history for the week with highs and lows.

I had the same frustrating experience with a dbl door Dometic fridge. After doing a bunch of the same mods you did, I finally added a three fan cage to the evaporator fins inside the fridge. That totally fixed the issue. It has been like a while new machine. It sits anywhere between 35 to 37 most of the time now. Even when in 90s outside.
