Hope to put a thermostat switch and neaten up the whole deal later on.

Only fridge I had problems with as far as cooling goes, was the one in our forester, in the slide. In that case, replacing the thermistor with the adjustable one (snipthetip.com) did the trick.
mine is the DM2852RBX looks like the same wiring diagram, mine did not come with fans, I spent 1hr trying to find out why it would not work (no sound) but would light in gas. after checking everything over and over came to the realization that it is working after I walked away for 20 minutes to get my laser thermometer and the freezer was at 40 and dropping. I know a little about fridges and everyone I worked on has a pump not sure how this thing works...

Well. The last few days were close to 85 and with all 3 fans on the frig temp rises to 42-45 mid day and drops to 30-32 overnight. That's a big spread. These slide mount frigs just do not perform like my two previous inside frigs.

Given your issues, I decided to check mine as we prepare for 4th of July camping. I'm testing the fridge right now. But even with temps right at 80, the freezer registered 13 after the fridge had been on overnight. Just finishing up a few things in the house and will go out and check the fridge portion and see what it is registering. The sensor has been in there for about 1 hour now, so it should have equalized with the door being closed.

We're heading to canton Texas tomorrow. It'll be hot and i dont want to bring an ice chest. Our spot will have shade til mid day. Sure wish this thing would cool better. From what I've read, freezer should get into minus numbers. Mine does but frig struggles.

Do you have internal fans?

I have found that our fridge works better on gas than on A/C. I think it has to do with the gas heating the ammonia more efficiently. Another thing that can affect the temperature is where the internal thermal couple is located on the fins. Higher up should make things colder and lower will make them warmer. Even though I have a temperature control I moved the thermal couple higher up the fin to give me a lower overall temperature.

Yes. I have 3 rear fans and one inside. I have an adjustable thermistor. The tan paint job and not having a roof vent have to be the issues.

From talks I had with Dometic the lack of vertical venting is an issue when it comes to overall efficiency. This was the reason for adding the fan/fans and requiring a shield of some type to force the hot air out the upper vent.
