I got some time today (and some energy) to mount the fans. On one fan I took some spare sheet aluminum and cut out a circle with hand snips and mounted the fan. Be real careful using hand snips like this, lots of razor sharp barbs since you cant continuously cut. I wrapped the edge in electrical tape, that seems to work well enough. On the other fan I used some bar stock and mounted the fan midway. I also wired in a quick connect, another purchase from Amazon, so whatever is mounted below can easily be removed.







My thought is to reuse the old fixtures for right now till I have more time to fabricate new fixtures The problems that brings are managing the wires to the motor and the power to the fixture. The flat sheet makes that more difficult, but it provides a much better mount for the fan for air flow.

Here is the jury rig of the light fixture attached to the wiring for the fan and power. Setting the fan to exhaust on a medium to low speed, I went to the rear vent and opened it up and could feel a nice breeze being pulled through. Setting the fan on a higher speed and it sounds a bit like a turbine winding up which I attribute to the smaller size I ended up with. In hindsight I might have gone with a 10" fan or 12" which may have moved more air but I think these will do fine especially with one bringing air in and one exhausting out.

I also left the fan running on about the middle setting for a half hour and felt the heat sync on the controller. There was no appreciable heat so I think these controllers will work fine.




Here is a shot of the light lit up on full.



I'll spend some more time tomorrow trying to neaten this up and mount the light. It will help to keep the trailer cool while I get the rest of the work done.

Worked on the trailer for three days in a row and I've given the fan a good test, having it run most of that time. The controller never got warm though I did have some issues with the connector I bought to make it easy to disconnect the light fixture from the fan.

I cleaned up the installation, this is pretty much how it will be till I get around to making a new cover. In the mean time I'll work on some sort of face plate for the rocker switch and the speed control. I also need to fab up a second aluminum mount/baffle for the back vent.



Closeup of the controller:



I'm happy with the results. It pulls a nice breeze without being obnoxiously loud. If I had to do something over, I might have ordered a slightly larger fan but these two will do the trick nicely and I think last a long time. And the cost per vent is probably around 50-60 bucks with no plastic to crack in ten years.

Nyce!

For 'edge trim' you can find the 'door edge guards' that press over the edge of a car door to minimize chipping. It has glue already inside it. I have used it for many 'edge protection' applications... it works easy.. a little hit with a hair dryer or heat gun and.. you can follow curves easily..

Thanks for the lead. On the next one I'm going to use the jigsaw with a metal blade to cut it. Cant be much worse than the snips and probably wont have the sharp razor wire bits.

I have been thinking of doing this for a while and maybe sell kits. Bob, do you have an interest in doing this?

Here is an option that is actually made by Fantastic Fan. This already has the fan part figured out for you. You would just need to repackage it to fit your vent.

Amazon.com: Fan-Tastic 01100WH Endless Breeze Stand alone Fan: Automotive

I don't think so, but I'm willing to provide all the inspiration and tech assist I can.

I saw that fan. Not sure how much butchering you would need to do to make it fit. You could potentially make a box for it and mount it over the vent if you could remove the handle and feet and the power switch didnt get in the way.

We love the fan,, and your determination.,What I want to know is what kind of lights are in your light covers? looks like flourescent, or strip leds... I want some of these for sure.. my trailer is very dark (decor and design) and it is hard to have enough light. Please set me know. and thanks, Richard

This kit would end up costing as much as a fantastic fan but you would not be butchering the structure of your trailer. Unless there is some sort of structure between the skins you would risk falling through the roof if you step near a vent that is just attached to the sheet metal and there is no support structure under it.
