Well, during the camping trip the thermometer was reading incorrectly. After using a different thermometer the fridge was reading 34-39 in the morning and 39-44 in late afternoon with outside temps in the high 90s with high humidity at the beach. Sometimes it would climb up to the high 40s.

Before the trip, I installed two 120mm fans to help vent the hot air out the roof vent. Don't know how much it helped since I never turned them off the entire trip.

When I installed the fans I was going to install a temp switch, but after wiring the switch, it did not work. I could here the relay close at set temp, but the fans would not come on! And yes, everything was wired correctly. $8 worth of crap!! So I just hard wired to the 12 volt supply to fridge. I'm going to use this remote switch instead of temp switch.MSD Inc 12V DC on Off Remote Control Wireless 12V Output Relay Switch RM100 | eBay

Also, the drain hose crack and broke above the vent door! Why would they use corrugated plastic hose that gets brittle when exposed to heat!? During the trip I used a rag in the drip tray and rang it out. I will probably get rubber hose and slip it over the factory plastic hose to drain out the vent door.

I like the remote control idea.. I ordered a small 7 inch radiator fan and am going to mount it to my top
Vent in my fridge to be used as a exhaust fan. Should supply enough circulation I could always mount a secon if needed.

Dometic advised Forrest River that a fan kit IS required on the refridge that is located on the slide, and had my dealer install a fan on the rear of refridge just below the upper vent. Well, freezer works and always did, however, frigdge hits 55+ This past weekend, put a small fan in the lower vent area, aimed it at a 45 degree angle so the airflow hits the cooling unit(black cylinder) and the radiator. Temp went from 55 to 34 in 3 hours with an outside temp 84. The cooling unit and radiator was warm, not hot to the touch. As soon as I took the fan away, temp shot up to 54 in less than an hour and the cooling unit and radiator were hot. This refridgertor/freezer set up requires the fans to aid in airflow. My previous trailer, 2652 fridge was not on a slide and worked perfectly.

I have a Dometic DM2652 not installed in a slide and with no fans installed and it has been acting exactly the same. I won't go into detail, I did that in this thread, My DM2652 Story, but I will be installing two 140 mm ball bearing fans as soon as they arrive.

I am convinced that this refrigerator model has to have external fans to enable the refrigerator to cool down below 40 degrees.
