Thanks Boomer for giving me the idea with all your pictures and processes. The install was easy and all the comments on the thread should benefit others as they did me.

Just returned home from a 2600 mile 8 state trip from Texas to Wisconsin and back. The day before the trip, I started the fridge and it was nice and cool at 33 degrees. We packed it and pulled the trailer out from the cover with the slide in direct sun and 100 degree weather. Temps climbed to 40 degrees. During the first night, temps stabilized and we were good to go at 35 degrees.
In the cooler weather states and as the fridge emptied out, temps ran at 33 degrees and would climb a couple degrees as the doors were opened.
On the return trip home the last two days were 95 and 100 degrees days. Temps in the fridge were 33 degree upon arriving at the camp grounds. It wasnt until we started opening the door did the temps climb but nothing greater then 38 degrees.
Couple things I noticed. 1) I measured no difference in food temperature when the fridge was 33 vs 40 degrees. 2) The first day when the fridge hit 40 degrees, the evaporator fin inside the fridge measured 28-30 degrees.
This leads me to believe I need some air movement inside the fridge. All in all, very happy with my fan mods both on AC and Propane.

Boom 'r, thanks for all the advice and the time you spent with this post for so long. I am just now finishing reading all the posts and about to tackle the mod on my vent cover with added fans. It looks like on your new 5er you just cut into the top row of vent area and set the fans on top of the middle row. is that correct? I just have a 6 cu ft fridge and so the two Titan fans should make a huge difference. Now that you have done two mod, do you feel that the two fans together or spaced apart is the better set up? One item that I have not read and have not figured out is that with the temp sensor included is where does it need to go? Right next to the fins or someplace else? The older I get the steeper the learning curve is getting. lol.

Hello lorend and thank you for the kind words...
I'll answer your questions as best as I can :
1. Keeping the fans together or apart was driven by the type of outer vent cover I was attaching. In the first rendition keeping the fans together was easier and very functional. But when I wanted to make my second attempt look nicer by using the Famco covers, it worked better to separate the fans. That way the Famco covers each had something to attach all 4 corners.
2. I had to cut away part of each the top and middle rows to fit the fans.
3. I did not even use the temp actuator wire on the first install. On the second I fed the wire thru some holes that were all ready drilled in the fins. But frankly I have yet to even use that feature.
And I agree with a smaller fridge you will see a dramatic result with these fans. With our 12cf fridge we saw improvement but I still need to improve the chimney design behind our fridge.
Take pics as you do your project and post them here for the rest of us to see and learn from!
Good luck!2021 Winnebago 2932 5th wheel

I am still evaluating what if anything I should do to help my slide-installed refrigerator. I have seen vent cutouts with installations and other creative ideas.
While they all have logic, I really like what you have done. My unit already has the baffle that GD installed when they made the unit. We can hear the two fans behind the refrigerator running a great deal of the time when it is hot. I like to ease or help life with something like you have done without changing the vent cover. So with that said, you simply added this fan unit to the interior upper vent framing. I keep reading about triple connectors, yet see where one can simply attach the ground and positive two wires to the refrigerator's 12V input source. In some photos, I see the connection but there is no mention of what was done with the third wire in the wrapped line. One even said it was not needed but the wrapped lines made it easier to work with. I am not an electrician but do understand the basics. Is the third wire needed and if so, for what? Could I simply set the control to auto and place that between the vent cover and GD baffle? I know, too simple...Last edited by terryriddle; 06-29-2022 at 04:23 PM.

Thanks for the insight. I could also place the controller on the lower edge of the frame (vent frame) on auto...or a set manual speed with them running when the refrigerator has power. Correct? Or do I even need a controller that comes with this fan unit...
