is it 110v fan with a voltage reducer or a 12v fan reduced to 3 volts? Or are you sure it said volts and not 3 amps? If it is 3 volts, it should come with a step down unit built in.

I can't tell by the description in the link. I suspect it is a 12 volt dc fan that steps down to 3vdc. Guess you will have to ask when you call the company. Let us know. Jim

I had Keystone install one under warranty as it should have been installed at the factory.

Most Montanas built in the past several years already have a supplemental cooling fan in the cavity behind the frige. Are you just wanting to experiment with more flow?

The description looks similar to other fans that it use batteries to get the 3volts they need, and with the short description it looks like it uses batteries if it matches other fans at 3 volts with batteries.
They have other models with wires that I'm guessing you connect to 12v on the rig (I wouldn't know where).

I'd rather not use batteries. I guess I'll keep looking,12 volt would be better so I don't have to worry about changing batteries. I saw a post somewhere in the forum of others that have installed some type of fan behind the refrig for extra cooling when the weather is hot but I haven't been able to locate the post so far ...

With Dometic units that are in a slide, the fan is required and Keystone should do it under warranty. My fan is 12 volts and has a thermatic control attached to the heat tube on the fridge.

Allied Electronics has quite a selection of fans. here is one that I am using. I picked this one because it is quiet and has low power consumption.

I have a switch to turn it on when I know it will be warm, but then I also installed a thermostat. The thermostat was an old household one with the mercury switch. I only have one fan, seems to do the job just fine, but like the two fan idea.

I am using a 110v fan in the rear cabinet area behind the outside door of ours. After more than a week with highs from 100 to 112, the fridge and freezer were struggling. The fan took care of it. However, I just bought a little 110v 4-inch $6 fan from Walmart. The 110v outlet in that cabinet is a single outlet and the fridge is plugged into it. Because of it's location I had to find a vertical adapter, for a couple bucks, and now have the fan and the fridge plugged into it. The fan has an on/off switch.
For now the fan is wedged in there and the lower left corner of the cover won't latch so as it cools I will see if I can rearrange things in there. If not, then I'll just remove it when not needed. It's just a matter of unplugging it and pulling it out.
My point is the 110v fan works just fine. But, of course, you have to have shore power or a generator running for it to work. But when it's hot enough to need it we're not likely boondocking anyhow.
