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.
