So, I bought it, took it home, and plugged it into the wall using the power brick that came with it. It has 2 speed, one less than the Fan-tastic, and it worked real well. It was a lot quieter than those little bunk fans, and moved a lot more air. Now, came the dilemma of how to mount it. So I took it apart and found a lot of open areas that I could work with. So, here is what I did.
I bought some threaded eye hooks at Home Depot, some extra nuts, and some regular and fender washers (to spread the weight on the plastic, probably overkill), and some light duty decorative chain. I was going to attach permanent eye hooks to the camper, but Jen said to try and use the 3M stick on hooks, due to the fact that we want to upgrade and not depreciate the trailer with extra holes (she is my brain sometimes).
The next thing, how to power it. This fan operates on 12VDC via a power brick, or, by 6 D cell batteries. In my tests, the 6D cells, providing 9 volts, didn't perform as well as the 12VDC. So, I went to Radio Shack, Bought the correct adapter tip, female to female 6 foot cord (which I cut in half), and Solderless 1/4" Audio Plug.
This setup seems to work great. With the chain, I can adjust the angle of the fan. The 12 volts means that it can run at any time. The one thing that I want to get, next time I order from Amazon, is a 1/4 splitter. That way, I can still use the stock bunk light, and use this fan, at the same time.
