There is a muffin fan inside the fridge, but adding another may be my next step depending on my results.

Im running 4 fans. 3 inside the fridge and 1 outside. Going on my 3rd year of mega hot full timing with an absorption fridge. I want to help you if interested. Ive tried lots of weird stuff. The old folks on here 24/7 wont comprehend these new techniques. Their intentions are good but their info is just mediocre outdated nonsense they typed over and over back in the day. Up to you to decide. All im trying to say if that if youre in AZ and its 110F outside i can help you to make your absorption fridge get below 40F.

Is the fan battery powered?
If yes, it might work better inside the fridge blowing onto the cooling fins.
You need both. Fans inside the fridge. Fans behind the fridge in the vent area.

The evaporative cooler might be supplying enough air flow in the vent area. If thats the case, putting the other small fan inside the fridge blowing onto the cooling fins will help a bunch.

Just placed arctic air evaporative cooler in the outside fridge compartment tonight. Also had a very small fan on hand. Also in there pointed up.
Will report back.

I have two 12V computer fans blowing air upward in the back of the fridge. They are mounted about half way up the back of the flue. Getting the heat to rise out of the flue is the key.

Me too, a considerable help…

It can be done rather clean. The 4" size makes it easy.
4" hole saw
4" flexible duct
4" grill to make it look nice on the outside.

Depending on your layout its possible you could drill a 4" hole inside your lower kitchen cabinet that is next to the fridge. Then just crack open the cabinet door to let cold air into that space.

When running on propane i would cover the 4" hole with something. 4" pipe plug might fit perfect. Even duct tape would work as you would not see the hole inside the cabinet.

Use a fan to blow the air from the cold cabinet into the warm fridge ventilation area. Im currently feeding 79F cold air into my fridge vent space. Outside air must be in the high 90s. Fridge air temp hasnt gone over 39. The technique works good if youre using the trailer AC anyway. Danger is propane leaking back into the trailer. (although it would most likely fall down and out of the side vent of your fridge, since the 4" hole you drill will probably be higher than the lower vent) Adding a secondary propane detector wouldnt be the worse idea for added safety. Or dont try the technique at all. Only sharing because it has worked good for me and i understand the danger. I have my propane turned completely off on days like this. Not gonna be cooking inside on the stove.

Great idea Wopachop.

Any comments or education welcome.
thanks..

Not the safest approach but if youre living inside the unit with your AC running figure out a way to let the cold interior air enter the back section of the fridge. Ive been doing that for awhile. Most people dont really understand the concept. It works pretty good if you are already spending the money to cool the inside of your trailer and stuck with an absorption fridge. You can vent 80F degree air up the back of the fridge instead of 110F.
