Refrigerator exhaust side vent fans

[Idaho54]

I work as a camp host for bureau of Land Management in the desert I was wondering if anybody's ever added any of these Titans vent fans behind the refrigerator vent

Lots of discussion on adding fans to make the fridge cool better. Just be sure to get quiet ones. Especially fridges in slide outs.
Lots of YouTube videos. You don’t have to use titans.

Not a make you mentioned, but I installed a 220 mm themaltake fan wired to existing fan wires and mounted to exhaust on top vent. Moves 129 CFM. Quiet and works well. $15

Im not familiar with the Titan fans, but I did install two Valtera 4” tunnel fans with modifications under the condenser using some 1/8” craft plywood. Two fans & a two way rocket switch to power either one fan, or two. The difference of having these fans vs not having them is remarkable. Last year camping at Assateague island Md in 100 degree direct sun on the vent side of the camper, the refrigerator stayed on average -5 to 5 freezer,/ 34 to 38 food.. Any fan under the condenser to help dissipate & expel the heat will benefit the refrigerators performance.

I did because we live in the desert also and getting the fridge to cool enough to load is a problem. I did this in the previous RV also. It makes a few degrees difference but not much when temps are over 100.

Something to consider- Placement of the fan can make a lot difference. Just mounting a fan on the inside of the vent grill may not optimize efficiency. That will certainly pull the warm air up through the channel from the lower vent, but not necessarily pull the heat specifically away from the finned condenser. IMO you need air blowing through the hot fins to make a significant difference.
