If you search the forum I'm sure there's a write up somewhere. Pretty easy if you can get access.

Many years ago, I had a Scamper pop-up truck camper. I added a small solar power fan in the "flue" area near the coils and it really helped. We were in Moab and the inside of the refrigerator was only 50 degrees, after adding the fan it got down to 40 degrees. It was a kit made specifically for RV refrigerators. Came with fan, small solar panel and all wiring & mounting hardware.

We have added 4" computer fans to both inside and outside. Outside has inline fuse and button style thermostat that comes on about 90˚F. Inline fuse is important...some times we like to turn it off. Inside I rigged, 12V supply for Fridge to a switch cut into controls face panel. Salvaged PC fan is zip tied underneath bottom rack. Will try to strategically stock small Fridge and turn on during hot days for interior circulation. Looking to do more with less. Results after next trip.

Another thing that kept temp a little more even was a twin D-cell fan that sat in door where drinks might go. Fan and motor were tiny and would surprisingly run a month.

I added a pair of 80mm box fans on t-stats to our first camper when it had a 3 way fridge in it. I placed them inside directly behind the top vent blowing air out. They helped, but my ice cream still melted.
I powered them off the fridge itself, so any time the fridge was on they were on. I also had a manual switch to both turn them off and force them on no matter what the t-stats were doing.
After the ice cream episode I replaced it with a compressor fridge and haven't looked back. Working at it's best (calcification cleaned out, fans on, etc., etc., etc.) the best that the 3 way could manage was about 40° below ambient. If we lived in the North instead of on this Coastal Desert, and only visited cold places that would likely be fine. Because we do not, that wasn't good enough.
Where does that road go?

I live in southwest Washington and we are having a record setting heat wave this weekend. Triple digits all weekend long which is unheard of around here.
I’m overall satisfied with this 3 way refrigerator, but realize in real high temperatures it is going to struggle.
