Adding fan behind refrigerator...worthwhile??
I have 3 RVs and I seem to be addicted to adding stuff to them....lol. They each have a standard Dometic 2852 absorption refrigerator. They seem to be working as expected. I did replace the cooling...

One side benefit of having a mask with fans at the top is reduced air flow in the winter. This helps prevent the fridge from freeze up, but is not enough to assure it.
I do know that without the fans first cycle from ambient (65 f) was about 8 hours on electric. After the fans that dropped to about 4 hours.
I have an adjustable thermostat which I tweaked over several trips.

FWIW, I feel that having fans at the top, and setting it up so they work to pull air through the coils, will inhibit the air flow if the fans aren't running, so you'd have to run the fans all the time. It may work more efficiently, but IMO the fans would have to run constantly to keep temperatures down. I have my fans down at the bottom just for that reason.
you need less fans as it is a more lamaner air flow. when a fan isn't turning there is still plenty of flow alowed through it, especialy since you might be putting one or two 4X4" fans at a opening that is about 8X16" its kind of like pushing a rope vs pulling it, the smoothest way to direct air flow where you want it is to put the one side in a vaccum and using baffels to direct it, the other way is to put a bigger or multi fans below and force it at the baffel but not all the air will go throuhg the baffel which is why you need more.
But if you don't completely cover the opening you're trying to pull air through, you're just going to pull air from around the sides of the fans, not up through the opening. That's why fans are shrouded. And, I agree you'll get some air through the fans if they're not running, it's not going to be very much as the fan blades will block any straight through air flow.
