I've now removed the 120's and installed 2 80 mm fans in the ducting vent.
I found that there was a filler panel that I could remove and cut to fit the fans on it .
Now the fans are horizontal blowing air up the vent stack.
I'll take pics tonight

#####Please learn from my mistake####

I had a hard time cooling my fridge in July at Myrtle Beach so I bought a computer fan and installed it in the bottom blowing up. It made it worse, my fridge warmed up even more and we had to throw everything away. Those bottom coils have to get hot for the fridge to work. All your trying to do with the fan is assist the chiminey effect to remove heat. The coils at the top are the ones that need heat removed. I since moved my fan to the top and it works great. I simply zip tied it to the top vent cover.

herk.
The solar panel fans should not run at night as there is no sunlight to create power for the fans.The relay would only switch the power from the solar panel to the fans when the fridge is turned on.I'm assuming you are talking about the the solar panels that are on the fridge vent.

Herk, if you go with solar fans you will want to put a toggle switch inline so you can shut them off when your trailer sits in the sun while NOT being used.

I knew I was "over thinking" this.
I was trying to make it automatic using a feed from the "run" DC line to power a relay to feed an inverted output photocell to power on the solar fans.

First off, the solar fans won't run at night anyway! (VERY embarrassed.)

Second, the relay will work (there are several cheap ones) but will increase battery drain by the amperage draw of the relay. (only a few milliamps buy I am trying to avoid battery drain at all.

A manual switch solves everything.

NASA invents the "Space Pen" at a cost of a million dollars.
Russia uses pencils.
